Engineering Data

■Derating Curve

Installation

Note: 1. Use standard mounting only. Using any other mounting

method will prevent proper heat dissipation and may result

in deterioration or damage of internal elements. Or, the re-

maining service life notice function cannot work properly.

2. If there is a derating problem, use forced air-cooling. The

ambient temperature is specified for a point 50 mm below

the power supply.

■Overload Protection

The Power Supply is provided with an overload protection function

that protects the load and the power supply from possible damage by

overcurrent. When the output current rises above 105% min. of the

rated current, the protection function is triggered, decreasing the out-

put voltage. When the output current falls within the rated range, the

overload protection function is automatically cleared.

Note: Do not allow the short-circuited or overcurrent state to continue

for more than 20 s, otherwise internal elements may deteriorate

or be destroyed.

■Overvoltage Protection

The Power Supply is provided with an overvoltage protection function

that protects the load and the Power Supply from possible damage

by overvoltage. When an excessive voltage is output, the output volt-

age is shut OFF. Reset the Power Supply by turning it OFF for at

least three minutes and then turning it back ON again.

Note: Do not turn ON the power again until the cause of the overvolt-

age has been removed.

■Undervoltage Alarm Function (Indication and Output)

When output voltage drop is detected, an alarm (a01) and lowest

output voltage value are indicated alternately. The preset value of

detection voltage can be changed in the setting mode.

(S8VS-06024@: The value of detection voltage is fixed at 20V)

Further, the alarm is output from the transistor ((11) DC LOW) to an

external device with the S8VS-09024A/B.

(Upon output voltage alarm: OFF; with no continuity across (11) and

(13))

Note: 1. Operation begins after about two seconds since the AC

power is supplied.

2. The alarm is not indicated in the setting mode.

3. Press the ((8) Mode Key) after the output voltage is re-

stored, to reset alarm indication.

4. The undervoltage alarm function monitors the output termi-

nal voltage of the power supply unit. To check the voltage

accurately, measure the voltage at the load end.

Note: Operation begins after about three seconds since the AC pow-

er is supplied.

2. The S8VS-06024@ is not provided with the setting mode

and its parameters are fixed at the shipment setting.

■Peak Hold Current Reset

Note: The peak hold current value is not reset in the setting mode.

■Total Run Time Monitor

Indication and Alarm Output

(S8VS-@@@24B)

The cumulative running hours of the power supply unit are monitored

as total run time. When the total run time reaches the predetermined

alarm set value, an alarm (a02) and the total run time monitor are

indicated alternately with an output issued from the transistor ((12)

Kh) to an external device. (The output is turned off when the total run

time reaches the alarm set value; with no continuity across (12) and

(13).)

The alarm set value can be changed in the setting mode.

Note: 1. The total run time cannot be reset. To reset the alarm, in-

crease the alarm set value beyond the value indicated as to-

tal run time.

Ex.) If a customer decided to change the load at 5,000

hours, when they turn the unit again the timing will start at

5,000 hours and on.

2. The alarm function (setting, indication, and output) is not

provided for S8VS-06024B.

■Self-Diagnostics Function

Note: 1. External noise is probable as a cause of “---”, “e01 ”, “e02” and “e03 ” errors.

2. Operation out of the derating curve area, ventilation error, and incorrect mounting direction are probable as a cause of “h%t” error.

3. If the “h%t” error state continues for about three hours, the maintenance forecast monitor function (S8VS-@@@24A only) becomes invalid.

The indication for maintenance forecast monitor remains as “h%t” even after the overheat condition is removed, and the Yrs output (12)

remains OFF (with no continuity across (12) and (13)).

Replace the power supply if this condition occurs even if the output is correct, as internal parts may be deteriorated.

4. The “h%t” error detection function is only for the S8VS-@@@24A.

■Undervoltage Alarm Indication

This indicator lights when the output voltage is insufficient.

Note: The display changes to the output voltage display when the

voltage is restored to the set value or higher.

■Multiple Alarms

When two or more different alarms occur at the same time

■Maintenance Forecast

Displays when the maintenance forecast has reached the set value.

■Indication and Output

When the product is purchased, “ful” will be indicated. As electro-

lytic capacitors deteriorate, indication changes to “hlf”. After the

remaining time to maintenance is reduced to two years, indication

automatically changes to a value, which decreases from “1.5” to “1.0”

to “0.5” to “0” (year) as the running hours increase.

If the maintenance forecast monitor setting is set to a value larger

than two years, value indication automatically begins after the

remaining time to maintenance is reduced to the set years.

If the remaining time becomes smaller than setting L (which can be

set arbitrarily between 0 and 5.0 years), an alarm (a02) and the

remaining time are indicated alternately.

With the S8VS-09024A, an output is given to an external device from

a transistor ((12) Yrs) to notify of the replacement timing, together

with indication. (The output is turned off after the replacement timing

is reached; with no continuity across (12) and (13).)

Note: 1. The remaining time to maintenance is based on continuous

operation, not including the time when the power supply is

turned off, and so may take longer to reach than the actual

time indicated.

2. Until the power supply has been turned for about one month

in total, indication is fixed at “ful” to estimate the extent of

deterioration, while the output remains turned on (with con-

tinuity across (12) and (13)).

■Maintenance Forecast Monitor Function

The power supply unit is equipped with electrolytic capacitors.

The electrolyte inside the electrolytic capacitor penetrates the seal-

ing rubber and evaporates as time passes since it is manufactured,

which causes deterioration of characteristics such as decreasing the

capacitance, etc.

Due to this deterioration of the characteristics of the electrolytic

capacitor, the power supply unit decreases its performance as time

passes.

The maintenance forecast monitor function shows an approximate

period left for maintenance of the power supply unit due to deteriora-

tion of electrolytic capacitors. When the period left for maintenance

that the power supply forecasts reaches the set value, an alarm is

indicated and an output signal is triggered.

Use this function to know the approximate replacement timing of the

power supply unit.

Note: The maintenance forecast monitor function indicates an ap-

proximate period left for maintenance, based on deterioration

of the electrolytic capacitor. It does not predict failures caused

by other reasons.

Relationship Between Indicated Values and Output of Set Values

■Principle of Operation

The deterioration speed of the electrolytic capacitor varies consider-

ably according to the ambient temperature. (Generally the speed fol-

lows “Rule of Two for every 10°C”; for every 10°C increase in

temperature the rate of degradation doubles according to Arrhenius’s

equation.) The S8VS-0@024A monitors the temperature inside the

power supply, and calculates the amount of deterioration according

to the running hours and inside temperature. Judging by this amount

of deterioration, the power supply will give the alarm indication and

output when the period left for maintenance reaches the set value.

Note: 1. Due to degradation of internal electronic parts, replace the

power supply at least once every 15 years even if indication

and output of maintenance forecast monitor are not issued.

2. The maintenance forecast is accelerated or decelerated ac-

cording to operating conditions. Periodically check indica-

tion.

■Reference Value

Note: The “maintenance forecast” is the service life (the power sup-

ply’s internal temperature is monitored at all times) of the inter-

nal electrolytic capacitor in actual operating conditions, and

varies according to the customer’s operating conditions. 15

years is taken as the maximum period of the maintenance fore-

cast.

Satisfy the following conditions when storing the Power Supply for

long periods of time to maintain its remaining service life function.

•When storing for more than three months, store within an ambient

temperature range of −25 to +30°C and the humidity range of 25 to

70%.

Periodic Inspection (S8VS-09024A

Model Only)

Under general operating conditions, the remaining service life func-

tion starts to work from several to ten and several years after start of

use. When the Power Supply is used for long periods of time, peri-

odically follow the procedure below to check that the remaining ser-

vice life function ((12)Yrs) is working properly.

1. Set to the Power Supply to the Run Mode.

2. Make sure that output ((12)Yrs) is ON (electrical continuity across

terminals (12) and (13)).

3. In the Run Mode, hold down the Down Key (10) and the Mode

Key (8) for at least three seconds at the same time.

The main display ((6)) changes to a02.

This function is working properly if output ((12)Yrs) is OFF (no

electrical continuity across terminals (12) and (13)).

4. Release the key to return to the regular mode.

Note: DC output is also maintained during periodic inspection.

Charging the Battery

If a battery is to be connected as the load, mount an overcurrent lim-

iting circuit and an overvoltage protection circuit.

Output Voltage Adjuster

Do not add unnecessary power. The output voltage adjuster (V.ADJ)

may be damaged.

DIN Track Mounting

To mount the Block on a DI track, hook portion (A) of the Block

onto

the track and press the Block in direction (B).

To dismount the Block, pull down portion (C) with a flat-blade screw-

driver and pull out the Block.

Series Operation

Two power supplies can be connected in series.

The (±) voltage output can be accomplished with two power supplies.

Note: 1. Connect the diode as shown in the figure. If the load is

short-circuited, a reverse voltage may be applied inside the

power supply unit, causing deterioration or breakage of the

power supply unit.

Select a diode having the following ratings.

2. Though products having different specifications can be con-

nected in series, the current flowing through the load must

not exceed the smaller rated output current.

Parallel Operation

The product is not designed for parallel operation.

In Case There is No Output Voltage

The possible cause for no output voltage may be the presence of an

overload or overvoltage condition, or may be due to the functioning of

an latching protective device. The latching protection may operate if

a large amount of surge voltage such as a lightening surge occurs

while turning on the power supply.

In case there is no output voltage, please check the following points

before contacting us:

Check the Overload Protected Status:

•Check whether the load is in overload status or is short-circuited.

Remove wires to load when checking.

•Attempt to clear the overvoltage or latching protection function:

Turn the power supply off once, and leave it off for at least 3 min-

utes. Then turn it on again to see if this clears the condition.

L-72 Switch mode Power Supply S8PS

■Overload Protection

50- to 300-W Models

The Power Supply is provided with an overload protection function

that protects the load and the power supply from possible damage by

overcurrent. The protection function operates when the load current

rises above an overcurrent set value (105% of the rated load cur-

rent). For a short-circuit or overcurrent lasting less than 20 seconds,

output voltage is decreased to protect equipment. When the output

current falls within the rated range, the overload protection function is

automatically cleared.

Note: Do not continue using the S8PS under short-circuited or over-

current conditions for longer than 20 seconds, otherwise the in-

ternal elements of the S8PS may be damaged or broken.

600-W Models

If an excessive current flows for 5 s or more, the output will be turned

OFF and simultaneously protection-ON alarm indicator will be lit. To

reset the S8PS, turn OFF the input voltage, leave the S8PS for at

least three minutes, and then apply the input voltage again.

Note: Do not continue using the S8PS with the output terminals

short-circuited or the overcurrent condition continued, other-

wise the internal elements of the S8PS may be damaged or

broken.

■Overvoltage Protection

The Power Supply is provided with an overvoltage protection function

that protects the load and the Power Supply from possible damage

by overvoltage. When the output voltage rises above a set value

(115% of the rated output voltage), the protection function is trig-

gered, shutting OFF the output voltage. If this occurs, reset the

Power Supply by turning it OFF for 1 minute min. and then turning it

ON again.

300- and 600-W Models Only

The overvoltage protection-ON alarm indicator lights when the func-

tion is operating.

■Overheat Protection Function

600-W Model Only

If the internal temperature of the S8PS rises excessively as a result

of fan failure or any other reason, the overheat protection circuit will

be triggered to protect the internal elements of the S8PS and simul-

taneously a protection-ON alarm indicator will be lit. To reset the

S8PS turn OFF the input voltage, leave the S8PS for at least one

minute and then apply the input voltage again.

Precautions

!Caution

Be sure to connect the grounding line. Not doing so may result in

electric shock.

!WARNING

Do not attempt to disassemble the Power Supply or touch its inter-

nal parts while power is being supplied. Doing so may result in

electric shock.

Do not touch the terminals of the Power Supply within one minute

after power has been turned OFF. Doing so may result in electric

shock due to a residual voltage.

Do not touch the S8PS or heat radiation fin while the power is be-

ing supplied or immediately after the power is turned OFF. Other-

wise, a skin burn may result from the hot Switching Power Supply

or radiator.

Mounting

To improve and maintain the reliability of the Power Supply over a

long period of time, adequate consideration must be given to heat

radiation.

The Power Supply is designed to radiate heat by means of natural

air-flow. Therefore, mount the Power Supply so that air flow takes

place around the Power Supply.

When mounting the Power Supply, mounting it to a metal plate is rec-

ommended.

Forced air-cooling is highly recommended.

It is recommended that the clearance around the Power Supply be

larger than those shown on page page 71 under Standard Installa-

tion.

Generating Output Voltage (±)

An output of ± can be generated by using two Power Supplies as

shown below, because the Power Supply produces a floating output.

Series Operation

Only models with power ratings of 100/150 W allow series operation.

As shown in the following diagram, the output voltage from each

Switching Power Supply can be added.

Parallel Operation

Only 300- and 600-W models can be in parallel operation provided

that they are operated under 90% of the ratings. Do not operate any

other models in parallel.

Make sure that the thickness and the length of all wires connected to

the load are the same to ensure that the wires will have no voltage

drop differences.

Fan Replacement

The service life of the fan is approximately 50,000 hours (at 25°C).

The service life varies, however, depending on the ambient tempera-

ture or other surrounding environmental conditions such as dust. As

a preventive maintenance measure, replace the fan within two years

if it is used at an ambient temperature of 40°C.

Fans are available as replacements.
