Technical Documentation
2. General description
ABT-PSM48/E Power Supply Manager is designed for distribution uninterruptible power supply of guaranteed 40…57,6 VDC and
24VDC of total maximum power up to 3,2 kW.
c The only dierence between ABT-PSM48 and ABT-PSM48E is the lack of 6 × 24VDC outputs in ABT-PSM48.
As a source of energy distribution, the Manager uses external modules of 800 W ABT-PS48800 Switch Mode Power Supply Units;
asasource of back-up power supply, it uses the VRLA battery bank of capacity up to 4x200 Ah. Use of 12V batteries with a capacity
of less than 40Ah can be used only for public address. ABT-PSM48 co-operates with maximum 4 modules of ABT-PS48800 Units,
ensuring safe connection for the purpose of parallel operations and monitors the output parameters of each Power Supply Unit.
ABT-PSM48 co-operates with the 4x12V VRLA battery bank; it maintains the bank in charged condition, ensures temperature
compensation of charging parameters and monitors series resistance of the battery and its wiring in compliance with Exhibit No.A2
tothe EN 54-4 Standard. Power Supply Manager and Power Supply Units are designed for assembling in a 19”IP30 Rack with other
Fire detection and re alarm systems elements.
ABT-PSM48 ensures uninterruptible switching to back-up power supply in case of mains power decay or failure of ABT-PS48800
Power Supply external modules. The Power Supply Manager is intended for systems requiring back-up power supply, including
those compliant to EN 54-16. Voice alarm control and indicating equipment.
The maximum conguration of the 54-4 compliant Power Supply Equipment includes:
• 1× ABT-PSM48 – Power Supply Manager
• 4× ABT-PS48800 – Power Supply Unit
• 1× ABT-PF4 – Power Supply Unit Frame
3. Unpacking the equipment
We ask to read this documentation in order to be familiar with important information concerning installation, operation and char-
acteristic features and functions of the product. When needed, the product should be shipped to the service station in the original
packaging (or identical with the original), like in the case of most of the electronic devices.
