MV VFD

Overview

STEP MV VFD is a Chinese-brand medium voltage variable frequency drive with over 25 years of experience. It features flexible terminal expansion without PLC, vector control, multi-level PWM sinusoidal output, low harmonic content (<5%), speed tracking start, and mechanical unit bypass. Suitable for cement, power, chemical, water treatment, textile, steel, mining, sugar, rubber, and tyre industries.
