48V 300A Telecommunication power system

48V 300A Telecommunication power system 1)48V 300A output 2) AC input 304V~476V 3) SCU monitor 4)5years warranty

1.Production introduction:

DAZ10-48/500,DAZ10-48/300 Combined power supply is composed of DA10-48/50,DA10-48/30 High Frequency Switching Mode Rectifiers,AC Distribution Unit,DM10 Control & Supervision Unit(CSU),DC Distribution Unit.The combined system is a complete one in which all of the compositions are installed in a 2000×600×600mm(H×W×D) rack.The number of DA10-48/50,DA10-48/30 rectifier can be selected according to the practical demands to form a power system of which the output capacity is 500A,300A.

Micro-computer is applied to control the system.Remote-Cen-tralized supervision & Control(RCSC) can be realized via RS458.RCSC can manage 1~100 supervision & control units in the power supply equipment.The operation and alarm condition of the system can be transferred into files for memory on time,you can consult and print them whenever you like.

DAZ10 Combined Power Supply is suitable for powering the Switching System,Mobile System,Optical Fibre Telecom,Microwave and Rural Telecom etc., especially can be applied for the unattended telecom system with integrated supervision,control,maintenance and management.
