The GP-2000 series Reliance Electric variable frequency drive, model 2GU21005 (often listed as 2GC21005), is a 5 HP, 200–230 VAC three‑phase VFD built to vary speed and torque of industrial motors. It accepts a 50/60 Hz three‑phase supply, with an input current of about 19.6 A and a 6.6 kVA class rating, delivering up to roughly 16.7 A of output current and a sine‑wave motor rating near 15.2 A. The unit is available in a NEMA 1 enclosure or as a chassis, and includes a built‑in keypad for local parameter adjustment, simplifying installation in control panels. Common applications include conveyors, pumps, fans, and other machinery that require precise speed control of a 3‑phase motor.
