48V50A Switching Mode Power Supply for communication use 

  

Model: AD4850

 

Introduction:

The 48V series high frequency switching power supply / telecom switching power supply, which is a high efficient, high performance and high reliable communication power supply. switching power supply specially designed for all kinds of communication and electronic equipments such as electronic program-controlled exchanger, microwave equipment, optical fiber communication equipment, etc. switching power supply adopts the most advanced international PWM technique and stable & reliable circuit topological structure. The switching power supply has many good points, including small volume, light weight, high efficiency, wide working temperature range, strong capacity of resisting disturbance, strong electric fence adaptive faculty, fast dynamic response, high stability, low noise and ripple, strong protection function, etc.

 

The 48V series high frequency switching power supply / telecom switching power supply still should be applied to NC machine tool, data processing and other equipments; they also can be used as the charge/discharge equipment of storage battery and automatically implement the protection to the storage battery.

 

The AD4850 is with N+1 combination of modules structure, which can be used in parallel.

 

Features:

• N+1 combination of modules structure
