DIN- and Chassis Mounting Brackets
PCB mounting as well as cassette style converters can be
chassis- and/or DIN-Rail mounted by means of Mounting
Bracket adapters. For selection and item numbers refer to
table below.
Note: Customized adapters for other case sizes are available
upon request.
Each item 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 pinnings and 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 (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 V
i max
= 80 V) and
72 VAC for PSA (withV
i 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.

×2-BCFG Electrical Description
This bracket allows the mounting of isolated DC-DC
converters IMR6, IMR15, IMP6 and IMP12 in 2"×2" cases with
either one or two output voltages of 5, 12 or 15 V. The
technical details are given in the data sheets of IMR6, IMR15,
IMP6, IMP12.
Depending on the application input transient protection may
be incorporated (e.g. an appropriate Transzorb diode D1).
