Servo Electronic Transformer

Servo Electronic Transformer

3-phase 380v to 220v Servo Motor Drive Electronic Transformer Power Supply for  Servo Driver System


  1. Instructions for use:

This product is an ultra-small-volume three-phase servo electronic transformer specially designed for the mismatch between the grid and the AC servo motor voltage. It has changed the problems of bulky, heat-generating, power-consuming and difficult installation of traditional coil-type transformers. It does not cause pollution to the power grid. It is an ideal product for solving power adapter problems in industrial control systems, and is fundamentally different from power-frequency transformers in terms of performance. There is a qualitative leap forward.

This product uses the most cutting-edge microwave devices, three-phase full-bridge switch resonant technology, SPWM modulation technology, completely eliminate EMI interference, widely used in Mitsubishi, Yaskawa, Panasonic, Sanyo, Delta, Dongyuan, Fujitsu, Hitachi, Omron, AB ,Frank,Schneider,Lost,Kobe,Lentz,Wide number…etc. All imported, domestic servo systems; The transformer capacity can be from 05KVA-80KVA, which satisfies the matching of all servo motor voltages.
