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. This device has the ability to provide settings within a series of responses that can maintain a standard motor torque to zero speed. This drive is maintained in a NEMA 12 type enclosure. It is structured for indoor use and does not have air vents. This enclosure is dust and drip-tight. This drive is 20.2 KVA, 50/60 Hz, and 380-460 VAC. It has a power loss of 600W.
The 20V4250 is equipped with several physical modules that include, two fan modules, a membrane switch, a printed regulator circuit board, a current feedback board, capacitors and a capacitor board, a diode bridge, and a gate driver PCB. The regulator board on this drive comes equipped with an RS-232 connection, a terminal strip for user I/O, and analog input and output jumpers. This board connects to the drive by sliding into the bracket system on the keypad. The user can then run a connector from the keypad to the J9 connection port on the regulator.
