Power Supply AP377

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

www.puls-power.de

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

See the web for current data sheet version:

(IEC 801) and VDE 0160 class 2 are satisfied even at
full load.

Fuse

The PSU has electronic protection against external
short-circuits. In case of an internal defect, a fuse
disconnects the unit. It can only be replaced by
opening the unit which should be done by the
supplier.

Installation for Operating

The unit is constructed for 19" systems:
Ensure that pin 4 of H15 connector is on top. For
other installation considerations consult your
representative. Ensure free air flow.

Dimensions and Connections

19" board, with totally enclosed Al/Mg alloy cassette.
8HP plug in width. See figure below for dimensions.

1) Do not remove any screws on box, as internal safety
connections could be disconnected!

2) Vout1 adjustable at trimmer1 (min. ± 5%),
