PULS AP377.121 INTRODUCTION
This triple-output power supply is highly efficient over the total input and output range. With low heat creation, it is small (8HP wide), light (770g), and convection-cooled.
The two forward converters automatically select between 115 and 230V AC ranges, avoiding faulty configuration. The converters have a fixed phase relationship, so Vout1 is independent of Vout2/3. The DP377 can thus provide a 5V DC output completely independent of, and isolated from, a 24V (2x12V) or 30V (2x15V) DC output.
EMC compatibility is a major feature. It has low spurious noise, and noise suppression meets VDE 0871 class B. Noise immunity meets IEC 1000-4-4 (IEC 801- 4) level 4 and VDE 0160 VDE 0160 class 2, even at full load. Over-voltage and over-temperature protection avoid problems even in extreme working environments. It is highly immune to overvoltage and transients, withstanding 300V AC input for 0.5s. IEC 1000-4 (IEC 801) and VDE 0160 class 2 are satisfied even at full load.
