Product Description

The 2V4451 was a Reliance Electric designed 2HP 380-460 VAC 3-Phase AC Drive in the GV3000 series. As part of a legacy series, the 2V4451 model of GV3000 drive was discontinued by the original manufacturer in 2009. With this taken into consideration, ABB and Baldor Reliance may have also sold this device depending on what years it was being produced. This particular offering is available for both repair and replacement right here at, with a standard lead repair time of one to two weeks. In case of emergencies, we offer 48-72 hour rush repairs for an additional fee, with the two-year guaranteed warranty standard to all of our GV3000 legacy series refurbished products. 

Hardware Tips and Specifications

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 has dual regulation capabilities, meaning it can flip-flop from using vector regulation to V/Hz regulation and back again depending on the needs of the drive user. 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.

Software Tips and Specifications

This 2V4451 model, like many refurbished and vintage Reliance Electric products, may experience the occasional fault in function. One fault that is known to inconvenience owners of the GV3000 series 2V4451 drive is the network communication loss fault, symbolized by the code nCL on the drive's built-in keypad display. This particular fault is caused by a loss of communication with the drive's established AutoMax network, and corrective action when faced with this fault includes ensuring correct function of the 2V4451 model's network master. If the problem doesn't seem to lie with the network master, additional checks on the network cabling from 2V4451's network master to its network option board are necessary. For more information on drive fault troubleshooting and specifications, please reference Reliance Electric's software start-up and reference manual D2-3359-6, available online here at


This 2V445 model is part of Reliance Electrics' GV3000 series, but has since been discontinued and is not currently manufactured by Reliance Electric. With this in mind, the drive's relatively outdated regulator version of 5.1 lends to its compatibility with older regulator printed circuit board types. Here at AX Control, we make a concerted effort every day to supply drive users worldwide with outdated and refurbished drive options, including several 5.1 version regulator boards. The product offerings we currently stock that remain compatible with the 5.1 version drives include:

Before making a purchase or installation of these drives, please ensure that your drive's voltage rating corresponds correctly with the regulator board version.
