DC/DC Converter DPD155
The DPD155 is designed to su pply up to 5A at 24V.
Output voltage is stable with ripple and n oise below
25mVpp over the total range up to 120W.
The high-efficiency flyback converter gives greater reliability and economy. Multiple units can be used in
parallel to increase system power without extra contro l
wiring, as the current is autom aticallc shared between
units (DPD155.133 and DPD155.134 only).
The design is immune to input disturbanc es according
to EN 61000-4-X, and VDE 0160 pulse (class 2 over the
entire load range!).
The unit is also protected against overvoltage and
short-circuits. Construction and design meet all relevant safety standards, such as EN 60 950, VDE 805,
VBG 804 and EN 55 022/B.

Fuse
The converter has electronic protection against
external short-circuits. In case of an internal defect, a
fuse disconnects the unit. It can only be replac ed by
opening the unit which should be done by the
supplier.
Installation for Operating
Install DIN rail TS35/7.5 horizontally, ensuring correct
orientation.
For other installation considerations consult your
representative. Ensure free air flow.
Dimensions and Connections
Fully enclosed Al/Mg alloy housing. All mechanical
dimensions are in mm.
1) Do not remove PE screw.
