1. Technical description.
1.1 General description
MPSB12 automation module is intended for indicating the operating status of buffer power supplies PSB 13,8V type.
The PCB board features LEDs that indicate PSU operating status (presence of AC voltage, presence of DC voltage,
battery voltage). The module is also equipped with technical outputs of: AC power loss, PSU failure, low battery
voltage.
