Description

Product Overview: Telecom power
The communication power supply is a new generation of products launched by our company after the electric operation power supply.

The product is combined with the actual operation of my country's telecommunications industry,and its various performance indicators have reached the international level,meeting the requirements of 20A-200A power supply capacity.Communication power supply in 220KV substation and small-capacity program-controlled switchboard,mobile base station, satellite earth station and other places.

Power system The DC system voltage(220v/110vdc) is transformed into a communication DC voltage (48vdc) by the DC/DC power supply module.It consists of a DC/DC module,a communication loop,a monitoring device,a switch and an acquisition module,and provides power for communication equipment.
