The 2GU41015-J is a 15 HP (11 kW) three-phase AC variable frequency drive from Reliance Electric GP-2000 series. It operates at 460 VAC. The suffix -J indicates a specific manufacturing origin or firmware version, while its electrical performance is identical to the standard model 2GU41015. This drive is designed for general industrial motor speed control and widely used on fans, pumps, conveyors and other standard machinery. The product has been discontinued, and refurbished units are commonly used for maintenance and replacement of legacy equipment.

2 represents the standard industrial drive series. GU stands for GP-2000 series with 460 VAC voltage class. 41015 refers to 460 VAC input, 15 HP rated power and hardware revision 15. The suffix -J denotes special production batch, manufacturing origin or dedicated firmware version.

Motor power is 15 HP (11 kW) with apparent power of 16.7 kVA. Input voltage is 460 VAC ±10%, three-phase, 50/60 Hz. Output voltage ranges from 0 to 460 VAC, three-phase. Output frequency ranges from 0 to 400 Hz. The maximum rated input current is 25.4 A. The continuous rated output current is 21 A. It adopts open-loop V/F control mode. Built-in protection functions include overcurrent, overvoltage, undervoltage, overtemperature, short-circuit and ground fault protection. It is designed with NEMA 1 enclosure. The operating temperature ranges from 0 °C to +45 °C. The overall dimensions are approximately 500 × 279 × 277 mm in height, width and depth. The total weight is about 25 kg. It complies with UL and IEC standards.

It is equipped with power terminals for three-phase main input, motor output and DC bus braking connection. The control terminals support ±10 V analog input for speed reference and 24 VDC digital I/O for start stop, fault reset and jog functions. It applies Reliance proprietary protocol and has no standard fieldbus ports. The onboard keypad and 7-segment display are used for parameter configuration and fault code inquiry. There is no encoder interface, and the drive only supports open-loop V/F control.

It delivers stable V/F speed regulation for 15 HP three-phase AC motors. It improves energy efficiency for variable-torque loads such as fans and pumps. It is compatible with external braking resistors to achieve rapid deceleration. Real-time status monitoring and fault code recording enable quick troubleshooting. Users can adjust acceleration time, deceleration time, current limit and I/O logic via the local keypad.

It is suitable for conveyors, packaging machines and assembly lines in light manufacturing industries. It matches medium-sized fans, pumps and agitators used in HVAC and process industries. It applies to conveying and lifting equipment driven by 15 HP AC motors. It serves as a direct replacement for outdated GP-2000 series drives in legacy automation systems.

Mount the drive inside a well-ventilated cabinet and reserve no less than 50 mm clearance around it for heat dissipation. Use shielded cables for power and control wiring, and fasten all terminals properly. Verify the input voltage before powering on. Energize the control circuit first and then the main power, and set relevant parameters according to the motor nameplate. Inspect wiring connections and clean internal dust every quarter. Disconnect all power supply and wait 5 minutes for DC bus capacitors to fully discharge before conducting any inspection or maintenance work.
