1SU44002 | Reliance Electric AC Drive 460 VAC 3HP

Description 

The 1SU44002 is an SP500 drive manufactured by Reliance Electric, featuring a rated horsepower of 2.0 HP and enclosed within a NEMA 4/12 enclosure. Operating with a rated voltage of 380-460 VAC, it falls under enclosure size B, with dimensions measuring 301.7 mm (11.88 in) (H) x 160.1 mm (6.3 in) (D) x 222.3 mm (8.75 in) (W) and weighing 5.4 kg (12 lb). Enclosed drives are designed for operation within temperatures ranging from 0° to 40° C (32° to 104° F). 

The F-06 parameter on the SP500 drive is Manual Torque Boost, featuring a step size of 1.0% within the range of 0-10%. Torque boost compensates for voltage drop in A-C motors at low speeds and provides high starting torque levels for friction or high inertia loads. Effective only at speeds below half the base frequency, users adjust the function incrementally from its 2% default setting until motor operation is satisfactory.

Information About 1SU44002

The 1SU44002 is an SP500 drive manufactured by Reliance Electric, featuring a rated horsepower of 2.0 HP and enclosed within a NEMA 4/12 enclosure. Operating with a rated voltage of 380-460 VAC, it falls under enclosure size B, with dimensions measuring 301.7 mm (11.88 in) (H) x 160.1 mm (6.3 in) (D) x 222.3 mm (8.75 in) (W) and weighing 5.4 kg (12 lb). Enclosed drives are designed for operation within temperatures ranging from 0° to 40° C (32° to 104° F). 

Manual Torque Boost, denoted as the F-06 parameter on the SP500 drive, features a step size of 1.0% within the range of 0-10%. Torque boost compensates for voltage drop in A-C motors at low speeds and provides high starting torque levels for friction or high inertia loads. Effective only at speeds below half the base frequency, users adjust the function incrementally from its 2% default setting until motor operation is satisfactory. 

F-07 parameter, V/Hz (Base Speed), operates within a range of 30-240 Hz with a step size of 1.0. This feature maintains a constant volts/Hz ratio, ensuring constant torque at any frequency. The frequency value entered establishes the volts/hertz curve, defining the base speed at maximum output voltage (230V).
