DPD155
1 Output
DIN Rail DC/DC Converter, 120 Watt
High efficiency: 85%
DCin wide range: 19.2...32V DC or 48/60V DC (@ DPD155.331)
WxHxD = 74x130x120mm
Parallel mode automatic load sharing (@ DPD155.133 and DPD155.134)
Voltage isolation primary/secondary: 2.5kV
Self-diagnostic LED and ready contact (RDY)
Meets EMV standards
EN 61000-6-2, EN 61000-6-3
NAMUR, VDE 0160/2
US (not for DPD155.331)
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 in parallel 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 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.
