User Manual
2. Characteristics and purpose of the document
This User Manual introduces the equipment user into correct operation and use of the ABT-PSM48/E Power Supply Manager,
ABT-PS48800 Power Supply Unit and ABT-PF4 Power Supply Unit Frame. Information on installation, electrical connection,
rstoperation and servicing is included in attached Technical Documentation.
Keep carefully this User Manual and any other attached documents for further reference.
Ambient System bears no responsibility for damages caused by failure to observe this document.
3. 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 × 24VDC 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 4×200 Ah. Use of 12V batteries with a capac-
ity 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. If the unit is used as a back-up power supply system only, no ABT-PS48800 units will be required. ABT-PSM48 co-operates
with the 4×12V 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 supply 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
