1. Technical description.

1.1. General description.

AC/AC PSAC 04244SEP power supply is using for supplying CCTV devices requiring AC voltage of 24 V with overall
efficiency of 4A@24V AC. The power supply is housed in a metal case (colour RAL 9003). The casing is equipped
with a micro switch that signals the opening of the doors (front panel).

Information about additional elements of PSAC 04244SEP power supply

- module of the AC/AC power supply in ABS casing, MSC 1512 (module of MSC 12V/1.5A or 24V/1A power supply,
exchanged voltage) allowing to create a 24 V AC and 12 V DC/24 V DC supply system.

AW output signalling failure of one of the outputs, relay type.
Attention! Fig.2 shows non-potential state of relay i.e. the state of failure

Jumper of the change in PTC/fuse-element safety device type

Fx jumper used, fuse-element protection device selected

Fx.x jumper used, polymer protection device selected

Jumper of the output voltage change (independently for each output):

U2 jumper used, voltage on OUTx= U2 output

Description of LB4-SEP elements

U1 jumper used, voltage on OUTx= U1 output
