Description

ABT-PSM48/24 Power Supply Manager is designed for distribution of DC Power Supply from Power Supply Units (PSU) and a back-up battery. The unit controls battery charging and distributes power supply to all Voice Alarm System (PA/VA) equipment at max 60 A.

The unit complies with the EN 54-4 VA standards and also EN 12101-10 Smoke and Heat Control System standards.

As a main source of energy distribution, the manager uses external modules 800 W (ABT-PS48800) for 48 V and 500 W (ABT-PS24500) for 24 V. PSM48 power supply manager uses internal power converter for 24 V equipment. As a source of stand-by power supply it uses the battery bank of the capacity of up to 200 Ah.

ABT-PSM48/24 cooperates with the 4×12 V / 2×12 V VRLA battery bank. It maintains the bank in charged condition, ensures temperature compensation of charging parameters and monitors serial resistance of the battery and its wiring as specified in Exhibit No. A2 to the EN 54-4 Standard.

ABT-PSM48/24 co-operates with up to 4 modules of ABT-PS4880/PS2450 Power Supply Units. The manager ensures safe connection for the purpose of parallel operations and monitors the output parameters of each power supply unit.
