Tips: Why you need a 1-phase 220V to 3-phase 380V VFD?
Due to national policies and regional restrictions, many areas will now withdraw 3-phase 380V industrial power. No 3-phase power in the region to apply for 3-phase power cumbersome procedures and a variety of labor costs and various hidden costs, resulting in some areas can not use industrial 380V power. and general industrial equipment, such as AC motors are mostly 3-phase 380V, in the absence of 3-phase electricity can not run. We can only find ways to convert 1-phase 220V to 3-phase 380V. However, many single phase 220V to three phase 380V equipment on the market are ridiculously expensive, so many users in need are discouraged. And the original machine can only be temporarily placed, or put into other places with industrial electricity to use.
ATO offers a series of 1-phase 220V input to 3-phase 380V output variable frequency drive from 1hp to 20 hp, which can drive 3-phase asynchronous motor soft start operation, for infinitely adjustable speed. The input power only needs single phase 220V, output three phase 380V, and the price is acceptable to most users. Our VFDs are about 1/10 of the price of the booster on the market, compact size, powerful, 0-400Hz can be adjusted at will, completely solve the embarrassing situation of industrial equipment without 3-phase power.
