WJ-C1 Series
Power range: 0.2 ～ 22kW
For applications with high overloads like hoists, flywheels, and heavy-duty start-ups
Highlights
The WJ-C1 represents a refined advancement of our proven WJ200 series of sensorless vector control (SLV) compact inverters. Combining high performance with intelligent control, the C1 is ideally suited for applications including textile machinery, materials handling systems, roller shutters, pumps, fans, and more. The C1 embodies the principle of “The Right Drive to Succeed.”
