Changhong Pure Sine Wave inverter

 

Changhong inverter has good load carrying capacity and load compatibility. Besides, built-in bypass switch greatly improves its continuity and reliability. Changhong inverter has good selected mating, which can cut off DC power supply in switch-on state and automatically switch to commercial power bypass power supply. It is more convenient to maintain and replace the rechargeable batteries, but has no effect on supplying power to load.

Changhong Embedded Charger

 

Changhong Embedded charger designed for charging up the Ni-Cd/Ni-MH batteries, is newly developed communication power supply system based on traditional switching power supply technology. It adopts CPU control circuit and monitor interface to realize the remote signaling, remote control, remote measuring and remote regulating of the rectifier module. Besides, adopting high frequency PFC and phasing resonance technologies greatly improve electrical properties, input voltage range and overall efficiency in particular.
