PULS DPD155.331 INTRODUCTION
The DPD155 is designed to supply up to 5A at 24V. The output voltage is stable with ripple and noise below 25 mVpp over the total range of 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 automatically 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.
