PSB-754813 v1.0/III
PSB 54V/1,3A enclosed switch mode buffer power supply
CODE:
TYPE:
EN**
DESCRIPTION
Buffer-type power supply units are intended for continuous power supply to devices that require stabilised voltage
of 48V DC (+/-15%). The power supply provides a voltage of U=54V DC with an output current of I=1A + 0,3A battery
charging *. In case of power voltage decay, prompt switching to battery supply occurs. The power supply unit is protected
against a short circuit, an overload, a surge or over voltage protection.
Under normal operation, the total current drawn by the equipment may not exceed I=1A. Maximum battery
charging current 0,3A. Total device current + battery 1,3A* max.
