Description

Special mounting supports have been designed for the

integration of power supplies into switch boards, control

panels, printed circuit boards, etc., using adapters for

chassis-, DIN-rail, or PCB mounting.

The 19-inch cassette type DC-DC and AC-DC converters can

also be chassis mounted with frontal access by means of a

special Chassis Mounting Plate, attached to the converters.

The Universal Mounting Bracket also fits to most of these

cassette type converters, allowing for either vertical chassis

or DIN-rail mounting.

Table of Content s Page Page

A Bracket Kit, consisting of a PCB with screw terminal

connectors and a bracket suitable for either chassis- or DIN-

rail mounting, is available either for PCB mountable PSR and

PSA Switching Regulators with option "Y" pins or for small

DC-DC converters 1 – 15 Watt.

For isolation of the PCB-mountable converters from a double

sided PCB, the use of Isolation Pads is recommended, as

described below.

CMB: Chassis Mounting Bracket

The kit consists of a PCB for the converter, a set of screw

terminals allowing for easy electrical connection and two

aluminium profiles, attached to the PCB by means of four

screws, which serve as the chassis mounting bracket. Four

different versions according to table 2 are available.

Details on the layout of the PCBs and diagrams are given in

the description below.

DMB: DIN-Rail Mounting Bracket

The DMB kit differs from the CMB version by a bracket suited

for DIN-rail mounting (according to EN 50022). The black

plastic body of the bracket holds the PCB by means of a

snap-in device. Four different versions according to table 2

are available.

Details on the layout of the PCB's and diagrams are given in

the description below.

C/DMBA01-.. Electrical Description

This bracket is designed for non-isolated Switching

Regulators of the PSR and PSA series in the A01 case size,

equipped with option Y. Technical details and further

information, e.g., max. input voltage etc., are described in the

PSR and PSA data sheets. The use of the optional inhibit-

and R-function (external output voltage adjustment with R1)

is possible, and the device can be driven either from a DC-

source or from a transformer secondary voltage.

– DC-input: Consider the forward voltage drop across the

rectifier diodes (also providing reverse polarity protection).

Capacitor C1 compensates the negative input impedance

of the converter in case of long connection wires.

– AC-input: The recommended transformer secondary vol-

tage is 48 VAC for PSR/PSA (with Vi max = 80 V) and

72 VAC for PSA (with Vi max = 144 V)

Exception:Input voltage for PSR54 (PSA55) is 20 VAC.

Note: PSR54 (PSA55) and PSR362 require an additional

capacitor (C2) of at least 470 μF.

Application-Specific Circuitry

The assembly C/DMB IMX/S7 offers a variety of additional

external circuitries which may be implemented onto the PCB

ZGN09601 A. See circuit diagram YSK 25300 S3 01. Please

also consult the IMS/X7 data sheet.

Depending upon the application the following pheripheral

additions can be made:

– Reverse polarity protection by a series diode D1.

– Improved input transient protection according to IEC/EN

61000-4-5, level 2, by chokes L1 or L2-A, L2-B (EMC

version) and capacitor C1.

– Remote inhibit.

Note: If the inhibit is not actively used the inhibit has to be

connected to Vi– by jumper B1.

– External output voltage trimming/adjustment

Single output units:

a)Vo – adjustment in the range of 70/75 – 100% of Vo nom by

resistors RX3 or RX4 or combinations of RX3/RX4.

b)Vo – adjustment in the range of 100 – 105% of Vo nom by

resistors RX1 or RX2 or combinations of RX1/RX2.

Double output units:

a)Vo – trimming by resistor R2 in the range of 100 - 105%

of Vo nom

b)Vo – trimming in the range of 70/75 - 100% of Vo nom by a

current diode together with a Zener diode D2 applicable

for 24/48 IMS 7 and 20/40 IMX 7 types.

– Reduced output ripple (by approx. factor 5) by using

chokes L3 / L5 together with electrolytic capacitors C8/C9.

– Improved electromagnetic emission EN 55022, class B,

lead length to load 1 m (class A for 110IMX7 types).

This requires all capacitors and output chokes as per circuit

diagram YSK 25300 S3 /01 whereby the coupling

capacitor C10 connected to Vi– via jumper B2 is foreseen

for 24/48IMS/L types and 20/40/70IMX7 types.

For 110IMX7 types the coupling capacitor C11 or C12

should be used connected to Vo+ via jumper B3.

Notes:

– For single-output models or double-output models with both

outputs in parallel, one filter set (L5 or L6-A/L6-B) together with

C7 and C9 is sufficient.

– Wire jumpers B2 and B3 should not be mounted together onto

the PCB as this would cause a short circuit.

– The coupling capacitors C10 or C11/12 should be Y2 ceramic

types to maintain the outputs SELV.

– Application specific assemblies are available on request.

DMB-K/S, DMB-MHQ

By means of these DMB mounting kits, the S, K, PSS, PSK

(DMB-K/S) and the M, H, Q, LPC, P (DMB-MHQ) converters

can be adapted to the DIN-rail. The kit consists of two

aluminium brakets to be mounted on each side of the

converter, including a clamp. The DMB-K/S kit contains two

different sets of screws for the adaption of the brakets either

to S/PSS or K/PSK converter types. The design of the kit is

made such that the fixture is very tight, and as a result the

assembly can also be used for mobile applications.

CMB-S

This mounting kit allows for chassis mounting of the S and

PSS Series converters, if access is only possible from the

front of the chassis.

Note: If space conditions are very tight, option B1 or B can be

used instead of the heat sink. Refer to the data sheets of the

respective converters.

This kit uses parts of the DMB-K/S kit since it consists of the

same two brakets but without the clamps and fitted the other

way round on the heat sink.
