WD200 series is a new generation of high-performance general-purpose inverter of Wolong, adopting advanced motor control algorithms, 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.

Product Features

Rich expansion interfaces: 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 motor (IM), permanent magnet synchronous motor (PMSM), synchronous reluctance motor (SynRM)

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

High accuracy: High speed control accuracy, IM:±0.5% / PMSM:±0.1%(SVC) ±0.02%(FVC)

High efficiency: Up to 98% efficiency

Outstanding current suppression: Suppresses inrush currents caused by sudden load changes, reducing equipment downtime

High performance: high-performance vector universal platform, new motor control algorithms
