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 style 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.
A Bracket Kit, consisting of a PCB with screw-terminal
connectors and a brackets 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 up to 15 Watt.
For isolation of the PCB-mountable converters from a double-
sided PCB, the use of Isolation Pads is recommended, as
described below.
RoHS-compliant products are available on request.
Note: All dimensions are in mm, unless otherwise specified.

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 fastened onto a DIN-rail. The kit consists of two
aluminum 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.

DIN-Rail and Chassis-Mounting Brackets
PCB mounting as well as cassette style converters can be
chassis- or DIN-Rail mounted by means of mounting bracket
adapters. For selection and part numbers refer to table 5 !
Note: Customized adapters for other case sizes are available
upon request.
Each part number gives a direct indication of the kind of
mounting, the type of converter, i.e. the case size, or the
output power as well as the possible pin-out and the options
according to the relevant converter data. The adaptors are
divided into two mechanical types: CMB and DMB.

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. The black plastic body of the bracket
holds the PCB by means of a snap-in device. Four different
versions according to table 5 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/PSA data
sheet. 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 for 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 V
i max = 80 V) and
72 VAC for PSA (with Vi max = 144 V)
Exception:Input voltage for PSA55 is 20 VAC.
Note: PSA55 and PSR362 require an additional capacitor (C2) of
at least 470 µF.

Mounting Instructions for Basic Kit
Single-output models IMX7, IMS7, IML10:
– Solder the wire jumpers into positions as below:
1. D1 (10.16 mm)
2. B1 (5.08 mm), inhibit.
Note: This jumper should be fitted, if the inhibit is not actively
used. An open inhibit disables the converter.
3. L2-A and L2-B, L6-A and L6-B (6.8 mm)
4. L4-A and L4-B (6.8 mm), only necessary, if the
R-input is used.
– Solder terminal blocks
5. X1: Position Vi+/ Vi–, 2-pole terminal block
6. X1: Position i/n.c., 2-pole terminal block
(only necessary in the case of remote inhibit)
7. X3: Position Vo+/ Vo–, 2-pole terminal block
8. X2: Position n.c., R, Vo–, 3-pole terminal block only
necessary in the case of Vo adjustment by e.g. an
external voltage source)
– Solder the selected DC-DC converter
– Mount PCB onto rails by using the 4 screws and nuts or
snap PCB onto the DIN mounting support.
– Perform function test
Double-output models IMX7, IMS7, IML10:
– Solder the wire jumpers into positions as below:
1. D1 (10.16 mm)
2. B1 (5.08 mm), inhibit
Note: This jumper should be fitted, if the inhibit is not actively
used. An open inhibit disables the converter.
3. L2-A and L2-B, L6-A and L6-B, L4-A and L4-B (all 6.8
mm)
– For applications with both outputs in parallel:
4. Place/solder jumpers B4 and B5, (5.08 mm)
– Solder terminal blocks
5. X1: Position Vi+/ Vi–, 2-pole terminal block
6. X1: Position i/R (Trim), 2-pole terminal block
(only necessary in the case of remote inhibit or
output voltage trimming by an external voltage
source)
7. X3: Position Vo1+/ Vo1–, 2-pole terminal block
8. X2: Position n.c/Vo2+/Vo2–, 3-pole terminal block
– Solder the selected DC-DC converter
– Mount PCB onto rails by using the 4 screws and nuts or
snap PCB onto the DIN mounting support.
– Perform function test
Application-Specific Circuitry
The assembly C/DMBIMX/S7 offers a variety of additional
external circuitries which may be implemented onto the PCB.
See circuit diagram and 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 models:
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 models:
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 IMS7 and 20/40IMX7 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 fig. 16, whereby the coupling capacitor C10
connected to Vi– via jumper B2 is foreseen for 24/48IMS/L
types and 20/40/70IMX7 models.
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 being SELV.
– Application specific assemblies are available on request:
MK001-xxx and MK002-xxx.

Isolation Pads for PCB Mounting
In applications, where PCB mounting converters are placed
on top of double sided boards, the use of Isolation Pads is
recommended. These fibre pads avoid short circuits and
provide excellent protection against possible damage to
tracks. For selection and item numbers refer to table below.
PCB-Tags for PCB Mounting
Switching Regulators in B02 or C03 cases may also be
mounted directly onto PCBs. The connection between the
converters' faston pins and the PCB can be easily made by
means of PCB-Tags.
