Low voltage drives

WD200 series high performance vector type low voltage inverter

WD200 series is a new generation of high-performance general-purpose inverter of Wolong, adopting advanced motor control algorithm, supporting AC asynchronous motor, permanent magnet synchronous motor and synchronous reluctance motor control, featuring high reliability, high performance, strong expansion capability, support for multi-transmission, and easy to set up cabinets.

Key Features

Wide range of interfaces as option

Two expansion interfaces can be expanded: I/O expansion module, speed feedback encoder module, communication module, etc.
Multiple control modes

V/F, open loop vector (SVC), closed loop vector (FVC), voltage-frequency separation
Supports multiple motor types

Three-phase asynchronous motors (IM), permanent magnet synchronous motors (PMSM), synchronous reluctance motors (SynRM)
High start torque

0.5Hz output 150% of rated torque (SVC); 0Hz output 200% of rated torque (FVC)
