Power Supply AP377

See the web for current data sheet version:www.puls-power.deThis triple-output power supply is highly efficient overthe 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 8014) level 4 and VDE 0160 VDE 0160 class 2, even at fullload. 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 atfull load.
