1.Introduction

DC Power Distribution Unit is suitable to indoor low voltage DC power contribution system. Mounted in a rack cabinet and connected between the -48V DC power supply and the protected equipment, it can protect the equipment from surge and instantaneous over voltage caused by the outside environment (lightning, electromagnetic radiation interference, etc.) or by the internal subsystems (switching effect, start and stop operation of inductive and capacitive loads), it is a Class C drawer type surge protector for DC power distribution with the following features.

19 inch 6U rack installation;
output 4 outputs 12V 50A;
Circuit breaker for each of the 4 outputs ,can disconnect the circuit when fault or overload happens
Easy connection for inputs and outputs wiring;
Insulation of output connectors;
Large current discharge capability and low residual voltage;
Remote signal alarm connectors (dry contacts of remote signal alarm is closed at normal operation while open at fault condition).
