1.1. General description
The MSC1512 PSU module is intended for supplying devices that require voltage of 12V or 24V DC. The
module is designed as a supplying component in CCTV systems, KD access control, SSWiN alarm systems, etc. It
is intended to be wall-mounted or fixed inside a device (e.g. camera’s enclosure).
- The module delivers current of: 12V with current efficiency of 1,5A or 24V with current
efficiency of 1A.
When supplied with the maximum AC power, the module enables supplying 12V DC cameras for a
longer distance (approx. 2x) than in case of 13,8V DC supply (with the same cross-section and resistance
of the wires). The module does not hale galvanic insolation between input/output (AC-AUX). For correct operation
of the module, the appropriate input voltage and current efficiency of the power source shall be provided.
Voltage drop for typical wires used in CCTV systems (2x 0,5mm2/AWG20):
