Product Description

System overview

The charging module adopts th series intelligent high frequency switching power supply independently developed by our company. This series of power supply is designed for power system and has the function of "four remote". The power supply adopts the world leading "resonant voltage type double loop controlled resonant switching power supply technology", which has the advantages of small volume, light weight, high efficiency (over 95%), high reliability. The products include three series of 220V, 110V and 48V, dozens of varieties, equipped with standard RS-485 interface, easy to connect with automation system, suitable for substations and switching stations with different voltage levels from 500kV to 10kV, power plants with 15mw-60mw power generating units, and national key projects such as subway, oil field, chemical industry, metallurgy, etc. The charging process is in line with the charge curve requirements of lead-acid battery and nickel cadmium battery. The system realizes intelligent charging management for the battery and has the function of temperature compensation. The monitoring system is equipped with standard rs-232/485 interface, which provides a variety of communication protocols, convenient access to automation system, open protocol, convenient networking, easy realization of "four remote" and unattended
