220V Power Frequency Pure Sine Inverter for Electric Power

 

Introduction:

 

KINGWOOD Pure Sine Wave Inverter / Power Inverter / Inverter Power Supply adopts the advanced SPWM and CUP control technology. With the strongpoints such as high reliability, perfect protection function, low waveform distortion and lower price etc.The inverter has high invert efficiency (in the condition of full load, the invert efficiency can be up to 85%). At the same time, this inverter have strong non liner load driving capability. Also, Inverter can control the monitor the input voltage/current, output voltage/current. Inverter can realize the function of unattended operation.

 

D Series 220V Pure Sine Wave Inverter / Power Inverter / Inverter Power Supply  is mainly used in power plant, electric power system, railway and other places.

 

Features:
