  • Weg CFW100 VFD Frame Size A

    WEG Weg CFW100A01P6S220G2 VFD 1.6A 0.33HP 220 VAC Single-Phase Input

    The Weg CFW100 VFD is one of the smallest in the marketplace, measuring only 2.17 inches wide, and a frame size A height of only 3.94 inches. The CFW100 series take in single-phase 110VAC or 220VAC and produces 230V 3-phase power to run electic motors from 1/4 HP up to 2 HP. The drive is fully programmable and even has a built-in PLC that can programmed for special functionality. A variety of I/O and communication option are also available. Features DIN-Rail Form Factor Easily replace contactor/overload setup with VFD. Robust Overload current to 150% for 60 seconds, Ambient Temp. to 50°C SoftPLC Flexible customizable applications programmable with ladder logic PID Controller Performance control based on parameter changes (pressure, flow, or other input) Communication Protocols Modbus-RTU,CANopen, RS-485, Ethernet and other options Conformal Coated Circuits Extends the life of electronic boards in corrosive environments, Class 3C2 oer IEC 60721-3-3. Caldwell Electric can setup VFD parameters and develop custom PLC programs to fit your needs for a nominal fee. A Note on HP: It is best to match a VFD drive to the motor based on nameplate current, rather than HP. This is because the drive power electronics are rated by current. To ensure the drive can handle the motor nameplate current, the drive's current should be at least as high as the full load amps of the motor.
