MD2020 PSU Power Supply Unit
The PSU module is the Power Supply Unit of the MD2020-CU control panel.
It is designed to meet the requirements of EN54-4.
It performs the dual function of managing the charge of an external battery and ensuring continuity of external power supply at 28 Vdc nominal, floating (isolated from the ground).
The output power is distributed to the LCU/BCU modules, LCU/BCU modules and fire detection system components through the T-BUS interconnection system and feeds the MD2020 control unit.
