208 - 240 V | 380 - 480 V | 575 V | 690 V

Unidrive M’s modular AC drive offering provides a flexible method of building compact, reliable high-power solutions. Paralleled together, Unidrive M can control induction and permanent magnet motors in systems up to 2.8 MW (4,200 hp).

Unidrive M differentiates itself on performance with extremely fast current control algorithms and high switching frequencies. Active Front End (AFE) solutions deliver unparalleled high performance regenerative control and ultra-low harmonic power quality.

The Unidrive M power modules can be paralleled into a wide range of flexible solutions to solve all system needs including Active Front End and multi-pulse rectifier configurations. They can be controlled by M600, M700, M701 and M702 controllers.
