1. Technical description.

1.1. General description

MPSB48 automation module is intended for indicating the operating status of buffer power supplies PSB 54V
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 OC and relay type: AC power loss,
PSU failure, low battery voltage.
