Adopting pulse width modulation integrated circuit and imported big power pushing module, this inverted power source has the features of quick reaction、interference-proof, auto frequency and voltage stabilized, low consumption of empty load、high efficiency and reliable performance. The inverted charging can be changeover by manual or automatically.It is an ideal equipment to provide AC power to these areas where is without electricity or the electric supply is often interrupted, also it can be used as supporting to the wind/solar generating plant. It is suitable in electronic instruments, electrical maintenance, laboratory, electrolysis and electroplating, measurement and test device, factory electrical equipment.etc.
