90 - 264Vac Input; 12Vdc, 500W Output

Safety Considerations

The CCR0512 power supply is intended for inclusion in other

equipment and the user must ensure that it is in compliance

with all the requirements of the end application.

This product is only for inclusion within other equipment and

must not be operated as a stand-alone product.

Thermal Considerations

The power supply can be operated in a variety of thermal

environments; however sufficient cooling should be provided

to ensure reliable operation.

Considerations include ambient temperature, airflow, power

supply dissipation and the need for increased reliability. A

reduction in the operating temperature of the power supply

will result in increased reliability. The thermal derating

presented in Figures 2-6 is based on measurements taken in

a wind tunnel.

Feature Descriptions

Standby Power Supply

A standby output, VSB, in the CCR0512 power supply comes

on when AC input in the operating range is applied.

Remote Sense

The power supply has both positive and negative remote

sense connections that can be connected to the positive and

negative rails of the main output near the load. Care should

be taken in routing the sense lines to ensure that noise is not

picked up or that additional filtering elements that affect the

stability of the power supply are not used. The power supply

will operate without the remote sense connections being

made, however if remote sense near the load is not used it is

recommended that the remote sense lines be connected

directly to the main output terminals.

Overcurrent Protection

To provide protection in a fault condition (output overload),

the power supply is equipped with internal current-limiting

circuitry and can endure current limiting continuously. At the

point of current-limit inception, the unit enters hiccup mode.

The power supply operates normally once the output current

is brought back into its specified range.

Overvoltage Protection

Overvoltage protection is a feature of the CCR0512 power

supply that protects both the load and the power supply from

an output overvoltage condition. When an overvoltage

occurs, the power supply shuts down and latches off. It is

necessary to recycle the input to restart the power supply

when this protection is activated.

Overtemperature Protection

The CCR0512 also features overtemperature protection in

order to provide additional protection in a fault condition. The

power supply is equipped with a thermal shutdown circuit

which detects excessive internal temperatures and shuts the

unit down. In the event of an over temperature condition, the

unit protects itself by providing a low warning signal for 10

seconds (typical) and then shutting off. Once the power

supply goes into overtemperature shutdown, it will cool

before attempting to restart.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout limit,

power supply operation is disabled. The power supply will

begin to operate at an input voltage above the undervoltage

lockout turn-on threshold.

DC OK

The CCR0512 provides a DC OK signal that indicates when

the output has come up and is in regulation. This is an open-

collector type signal that goes high when the output is

available and within regulation.

Paralleling/Load Share

This power supply can be paralleled to provide larger load

currents than can be delivered from a single power supply.

Up to four power supplies may be paralleled. Paralleling is

accomplished by connecting the Current Share signals of

multiple power supplies together. At load current levels

above 20%, the output currents of multiple power supplies

will be within ±5% of the full load value.

If remote sense is used when paralleling is employed, the

remote sense connection points should be common to both

power supplies.

The supply is equipped with internal Or-ring mosfets in the +

VOUT leg and designed for hot swap operation.

Signal Considerations

Signal Return

The signal return is the referenced for all the signals and is

internally connected to the output return (+VOUT return).

Fault Signal

TTL compatible. Open collector (High) for normal operation.

Sink current: 4mA. Max collector voltage: 12Vdc

This alarm is an opto-isolated open collector signal

referenced to +VOUT Return or chassis ground.

The signal indicates that a failure has been detected in the

unit (OTP, OVP, AC Fail or No Input).

Output Current Monitoring

Analog output signal. Voltage proportional to the power

supply output current (0.1V/AMP) +/- 250mv.

Module Enable

The power supply will turn on when the pin engages to the

mating connector and senses it connected to Signal Return. It

is required to tie the mating connector pin to the Signal

Return pin for the power supply to function.

PSU Present

Binary signal delivered when the rectifier is present (active

low, strap to return signal).

Load Share/Paralleling

Analog signal. Single wire connection. Unit will load share

within ±5% of full load.

GE Data Sheet

CCR0512FP Power Su

90 - 264Vac Input; 12Vdc, 500W Output

Over Temperature Warning

TTL compatible. Open collector (High) for normal operation.

Sink current: 4mA. Max collector voltage: 12Vdc. In the event

of an over temperature condition, the unit protects itself by

providing a low warning signal for 10 seconds (typical) and

then shutting off. Auto restart after the condition is cleared.

Output Voltage Programming

Analog input signal - voltage determining the rectifier output

voltage.

VOUT = 10.8V+ (Vprog X 0.96)V, for Vprog from 0V to 2.5V

VOUT = 13.2V, for Vprog from 2.5V to 3.0V

VOUT = 12.0V, for Vprog higher than 3.0V or left open

Remote ON-OFF

TTL compatible. Open collector (High) for normal operation.

Sink current: 4mA. Max collector voltage: 12Vdc

Logic 1 (TTL High) or open enables unit (ON); Logic 0 (TTL Low)

or short shuts unit down (OFF). Cycling this signal resets the

over-voltage protection memory.

DC OK

TTL compatible. Open collector (High) for normal operation.

Sink current: 4mA. Max collector voltage: 12Vdc

AC OK

TTL compatible. Open collector (High) for normal operation.

Sink current: 4mA. Max collector voltage: 12Vdc

AC OK indicates that AC is applied within the specified input

range for the rectifier.

Serial Bus Communications

All signals are referenced to ‘Signal Return’.

Device addressing: The microcontroller (MCU) and the

EEPROM have the following addresses:

Device Address Address Bit Assignments

(Most to Least Significant)

MCU 0xBx 1 0 1 1 A2 A1 A0

R/W

Broadcast 0x00 0 0 0 0 0 0 0 0

EEPROM 0xAx 1 0 1 0 A2 A1 A0

R/W

Address lines (A2, A1, A0): These signal pins allow up to eight

(8) modules to be addressed on a single I²C bus. The pins are

pulled HI internally. For logic LO connect to ‘Output Return’.

Global broadcast: This is a powerful command because it

instruct all power supplies to respond simultaneously. A read

instruction should never be accessed globally. The power

supply should issue an ‘invalid command’ state if a ‘read’ is

attempted globally.

For example, changing the ‘system’ output voltage requires

the global broadcast so that all paralleled power supplies

change their output simultaneously. This command can also

turn OFF the ‘main’ output or turn ON the ‘main’ output of all

power supplies simultaneously. Unfortunately, this

command does have a side effect. Only a single power

supply needs to pull down the ninth acknowledge bit. To be

certain that each power supply responded to the global

instruction, a READ instruction should be executed to each

power supply to verify that the command properly executed.

The GLOBAL BROADCAST command should only be executed

for write instructions to slave devices.

The I²C interface facilitates the monitoring and control of

various operating parameters within the unit and transmits

these on demand over an industry standard I²C Serial bus.

Serial Clock (SCL): Clock pulses are host generated initiating

communications across the I²C Serial bus, and are pulled up

internally to 3.3V by a 10kΩ resistor. The end user should add

additional pull up resistance as necessary to ensure that rise

and fall time timing and the maximum sink current is in

compliance to the I²C specifications.

Serial Data (SDA): This is a bi-directional data line, pulled up

internally to 3.3V by a 10kΩ resistor. The end user should add

additional pull up resistance as necessary to ensure that rise

and fall time timing and the maximum sink current is in

compliance to the I²C specifications.

Basic Operation

PMBus™ compliance: The power supply is fully compliant to

the Power Management Bus (PMBus™) rev1.2 requirements.

Manufacturer specific commands located between

addresses 0xD0 to 0xEF provide instructions that either do

not exist in the general PMBus specification or make the

communication interface simpler and more efficient.

Master/Slave: The ‘host controller’ is always the MASTER.

Power supplies are always SLAVES. SLAVES cannot initiate

communications or toggle the Clock. SLAVES also must

respond expeditiously at the command of the MASTER as

required by the clock pulses generated by the MASTER.

Clock stretching: The ‘slave’ µController inside the power

supply may initiate clock stretching if it is busy and it desires

to delay the initiation of any further communications. During

the clock stretch the ‘slave’ may keep the clock LO until it is

ready to receive further instructions from the host controller.

The maximum clock stretch interval is 25ms.

The host controller needs to recognize this clock stretching,

and refrain from issuing the next clock signal, until the clock

line is released, or it needs to delay the next clock pulse

beyond the clock stretch interval of the power supply.

Note that clock stretching can only be performed after

completion of transmission of the 9th ACK bit, the exception

being the START command.

Figure 13. Example waveforms showing clock

stretching.

I²C Bus Lock-Up detection: The device will abort any

transaction and drop off the bus if it detects the bus being

held low for more than 35ms.

GE Data Sheet

CCR0512FP Power Su

90 - 264Vac Input; 12Vdc, 500W Output

Communications speed: Both 100kHz and 400kHz clock

rates are supported. The power supplies default to the

100kHz clock rate. The minimum clock speed specified by

SMBus is 10 kHz.

Packet Error Checking (PEC): Although the power supply will

respond to commands with or without the trailing PEC, it is

highly recommended that PEC be used in all

communications. The integrity of communications is

compromised if packet error correction is not employed.

There are many functional features, including turning OFF the

main output, which should require validation to ensure that

the correct command is executed.

PEC is a CRC-8 error-checking byte, based on the polynomial

C(x) = x8 + x2 + x + 1, in compliance with PMBus™

requirements. The calculation is based in all message bytes,

including the originating write address and command bytes

preceding read instructions. The PEC is appended to the

message by the device that supplied the last byte.

SMBAlert (E4): The µC driven SMBAlert signal informs the

‘master/host’ controller that either a STATE or ALARM change

has occurred. Normally this signal is HI. The signal will

change to its LO level if the power supply has changed

states and the signal will be latched LO until the power

supply receives a ‘clear’ instruction as outlined below. If the

alarm state is still present after the ‘clear_faults’ command

has been received, then the signal will revert back into its LO

state again and will latch until a subsequent ‘clear_faults’

signal is received from the host controller.

The signal will be triggered for any state change, including

the following conditions;

 VIN under or over voltage

 Vout under or over voltage

 IOUT over current

 Over Temperature warning or fault

 Communication error

 PEC error

 Invalid command

 Detected internal faults

The power supply will clear the SMBusAlert# signal (release

the signal to its HI state) upon the following events:

 the STATUS_BYTE (0x78) or STATUS_WORD (0x79) are

read

 Receiving a CLEAR_FAULTS command

 The main output recycled (turned OFF and then ON) via

the REMOTE ON/OFF signal pin

 The main output recycled (turned OFF and then ON) by

the OPERATION command

Read back delay: The power supply issues the SMBAlert #

notification as soon as the first state change occurred.

During an event a number of different states can be

transitioned to before the final event occurs. If a read back is

implemented rapidly by the host a successive SMBAlert#

could be triggered by the transitioning state of the power

supply. In order to avoid successive SMBAlert# s and read

back and also to avoid reading a transitioning state, it is

prudent to wait more than 2 seconds after the receipt of an

SMBAlert# before executing a read back. This delay will

ensure that only the final state of the power supply is

captured.

Successive read backs: Successive read backs to the power

supply should not be attempted at intervals faster than every

one second. This time interval is sufficient for the internal

processors to update their data base so that successive

reads provide fresh data.

Invalid commands or data: The power supply notifies the

MASTER if a non-supported command has been sent or

invalid data has been received. Notification is implemented

by setting the appropriate STATUS and ALARM registers and

setting the SMBAlert# flag.

If a non-supported read is requested the power supply will

return all 0x00h.

Notes: Settings and read backs above support the 12Vdc

main output. There are no adjustments or read backs of the

standby output. Failure of the standby output is reported by

the STATUS_MFR_SPECIFIC register. The code does not check

the validity of, or whether the data being changed is within the

expected boundary. The user is responsible to make sure that

data placed in the registers is within the monitored range.

Command Descriptions

Operation (01) : By default the Power supply is turned ON at

power up as long as Power ON/OFF signal pin is active HI. The

Operation command is used to turn the Power Supply ON or

OFF via the PMBus. The data byte below follows the

OPERATION command.

FUNCTION DATA BYTE

Unit ON 80

Unit OFF 00

To RESET the power supply cycle the power supply OFF, wait

at least 2 seconds, and then turn back ON. All alarms and

shutdowns are cleared during a restart.

Clear_faults (03): This command clears all STATUS and

FAULT registers and resets the SMBAlert# line.

If a fault still persists after the issuance of the clear_faults

command the specific registers indicating the fault are reset

and the SMBAlert# line is activated again.

WRITE_PROTECT register (10): Used to control writing to the

PMBus device. The intent of this command is to provide

OPERATION

Vout_Command (21) : This command is used to change the

output voltage of the power supply. Changing the output

voltage should be performed simultaneously to all power

supplies operating in parallel using the Global Address

(Broadcast) feature. If only a single power supply is instructed

to change its output, it may attempt to source all the required

power which can cause either a power limit or shutdown

condition.

Software programming of output voltage permanently

overrides the set point voltage configured by the Vprog

signal pin. The program no longer looks at the ‘Vprog pin’ and

will not respond to any hardware voltage settings. If power is

removed from the µController it will reset itself into its default

configuration looking at the Vprog signal for output voltage

control. In many applications, the Vprog pin is used for

setting initial conditions, if different that the factory setting.

Software programming then takes over once I2C

communications are established.

To properly hot-plug a power supply into a live backplane,

the system generated voltage should get re-configured into

either the factory adjusted firmware level or the voltage level

reconfigured by the margin pin. Otherwise, the voltage state

of the plugged in power supply could be significantly different

than the powered system.

Vout_OV_warn_limit (42): OV_warning is extremely useful

because it gives the system controller a heads up that the

output voltage is drifting out of regulation and the power

supply is close to shutting down. Preemptive action may be

taken before the power supply would shut down and

potentially disable the system.

OC and OT_fault_ response (47, 50): The default response

for both OC and OT is auto_restart (hiccup). Each register,

individually, can be reconfigured into a latched state.

Latched and hiccup are the only supported states.

Restart after a latch off: Either of four restart possibilities are

available. The hardware pin Remote ON/OFF may be turned

OFF and then ON. The unit may be commanded to restart via

i2c through the Operation command by first turning OFF then

turning ON . The third way to restart is to remove and reinsert

the unit. The fourth way is to turn OFF and then turn ON ac

power to the unit. Each of these commands must keep the

power supply in the OFF state for at least 2 seconds, with the

exception of changing to restart.

A power system that is comprised of a number of power

supplies could have difficulty restarting after a shutdown

event because of the non-synchronized behavior of the

individual power supplies. Implementing the latch-off

mechanism permits a synchronized restart that guarantees

the simultaneous restart of the entire system.

A synchronous restart can be implemented by;

1. Issuing a GLOBAL OFF and then ON command to all power

supplies,

2. Toggling Off and then ON the Remote ON/OFF signal

3. Removing and reapplying input commercial power to the

entire system.

The power supplies should be turned OFF for at least 20 – 30

seconds in order to discharge all internal bias supplies and

Vin_UV_warn_limit (58): This is another warning flag

indicating that the input voltage is decreasing dangerously

close to the low input voltage shutdown level.
