Inovance MD500T2.2GB-INT 2.2kW 3HP 480V VFD

Used Inovance MD500T2.2GB-INT 2.2 kW 3 HP 480V Variable Frequency Drive

Used Inovance MD500 series variable frequency drive, model MD500T2.2GB-INT. 2.2 kW (3 HP), 380–480 V three-phase, G-type heavy duty, built-in braking unit. Not installed in production. Used by engineers for testing only. (Some units are labeled under Benshaw distribution; the catalog model is Inovance MD500.) At time of listing, I have one with the Inovance label and the other under the Benshaw label.

**Includes Manual**

Intended applications

• Speed and torque control of three-phase induction motors
• Permanent-magnet synchronous motors (sensorless)
• Fans, pumps, conveyors, and constant-torque machine drives
• Applications that need vector control, PID, or Modbus
• Test bench or spare drive for an existing 380–480 V system
