IGBT or VMOS ducts,superior intelligent microcomputer CPU,SPWM and so on. Pure sine wave output,and it can be connected with
any kind of loads,such as Resistance capacitive load and inductive load. With quick reaction,anti-disturbing,strong adaptable and great
practicable ability.It is the best choice to be used on the occasion of bad electrical environment.

Main technical features
