Benshaw GM2 Series General Purpose Micro Drives

Benshaw GM2 Series General Purpose Micro Drives may be small, but don’t let looks fool you!

Benshaw’s new GM2 Series sensorless vector variable frequency drive family provides enhanced performance and reliable operation in a robust, yet compact, user-friendly design. These versatile drives are available with ratings from .5 to 15HP @ 240 or 480 volts, making them an ideal choice for distributor stocking programs. The small footprint of our new micro drives also makes the GM2 an attractive option for OEM panel builders with compact space requirements.

Benshaw GM2 Series General Purpose Micro Drives are easy to install, simple to program and offer dual ratings to support both normal and heavy duty applications.
