About the 20V4250
The 20V4250 by Reliance Electric is a 20HP Drive that was made to be used within the GV3000 product line, which is a sequence of drives and replacement parts. It may have been mass-produced by ABB or Baldor Reliance. This is version 5.0 of this particular drive and is now part of the Reliance legacy systems. AX Control might still have the 20V4250 in stock, however, so please consult our website for the availability of this product. The 20V4250 is an AC PWM (pulse-width-modulation) drive. It was built to:
- modify and adjust vector frequencies and general-purpose regulation
- provide settings within a series of responses that can maintain a standard motor torque to zero speed
- in a NEMA 12 type enclosure
- for indoor use and does not have air vents
- to be dust and drip-tight.
