2V4451

Product Description

The 2V4451 was a Reliance Electric designed 2HP 380-460 VAC 3-Phase AC Drive in the GV3000 series. ABB and Baldor Reliance may have also sold this device depending on what years it was being produced. 

The 2V4451 is a 1.5-kilowatt drive. It has a standard input amps of 4.2 and an output of 3.4 amps. This drive can flip-flop from using vector regulation to V/Hz regulation and back again. When using vector regulation, the device is capable of maintaining a 150% output current for 1 minute. When it uses the standard V/Hz regulation it can maintain a steady output current of 110%. This drive is covered by a NEMA 4X/12 rated enclosure. Its rating indicates that it is acceptable in NEMA 4X and 12 environments. This drive is not vented and has a drip and dust-tight chassis. It is not meant for outside usage.

The 2V4451 has many important internal components.  On the left side of the drive is a large capacitor board that contains six capacitors. There are two fan assemblies with one of them being internal. On the right side of the board is a current feedback board that has the ability to be attached to the regulator card. The regulator card is attached to a mounting bracket that is directly behind the built-in keypad. The regulator is positioned so that the display on the regulator can be seen on the keypad’s display. The keypad is connected to the regulator using the J9 connection. The regulator has a ribbon cable connection to the current feedback board and to a power module. It also has an RS-232 serial communications cable.
