Wolong’s WD200 and WD400 are both low voltage variable frequency drives (VFDs), but they are designed for different industrial needs.
The WD200 series is a high-performance vector control drive focused on precision, fast response, and advanced automation integration. It supports induction motors, permanent magnet synchronous motors (PMSM), and synchronous reluctance motors (SynRM). With powerful communication capabilities and flexible system integration, WD200 is ideal for demanding applications such as textile machinery, packaging equipment, CNC machines, and complex automated production lines.
The WD400 series is designed for reliable and cost-effective operation in standard industrial applications. It focuses on stability, easy commissioning, and efficient motor control for equipment where extreme dynamic performance is not required. Typical applications include fans, pumps, conveyors, and other general-purpose machinery.
