Product Details

Product description

Widely apply to the middle and large power three-phase USP, ESP three-phase frequency inverter.

Adopting software simulation design, to meet the special needs of the inverter circuit to the waveform compensation, effectively reduce the machine equipment electromagnetic interference, as well as using high quality silicon steel to process ,and H-level high-temperature copper(aluminum) wire to wind, can effectively reduce the mechanical shock noise.
