DC/DC Converter DPD155

See the web for current data sheet version:www.puls-power.de

The DPD155 is designed to supply up to 5A at 24V.
Output voltage is stable with ripple and noise below
25mVpp over the total range up to 120W.
The high-efficiency flyback converter gives greater reliability and economy. Multiple units can be used inparallel to increase system power without extra control
wiring, as the current is automaticallc shared between
units (DPD155.133 and DPD155.134 only).
The design is immune to input disturbances according
to EN 61000-4-X, and VDE 0160 pulse (class 2 over theentire load range!).
The unit is also protected against overvoltage andshort-circuits. Construction and design meet all relevant safety standards, such as EN 60 950, VDE 805,
VBG 804 and EN 55 022/B.
