Product Description
7FN4032 is a FlexPak 3000 non-regenerative drive controller that is manufactured by Reliance Electric. The input voltage is 460 VAC and the enclosure is a chassis. Optional features for the FlexPak 3000 drive include an incoming AC line disconnect kit, a fused blower motor starter kit with an adjustable overload, a NEMA 1 conversion kit, floor mounts for NEMA 1 and NEMA 12 enclosures, a remote mountable OIM kit (for mounting in cabinet doors), dynamic braking kits, an enhanced field supply kit, field current regulators, a pulse encoder feedback kit, an AC tachometer feedback kit, I/O expansion cards, a 115 VAC control circuit interface, an AutoMax network interface option card, a DeviceNet communication option card, a ControlNet communication option card, and CS3000 Windows-based software.
The drive’s displacement power factor at its maximum speed is 88%. The efficiency of the power module at 100% speed and with 100% load is 99.3%. The efficiency of the power module at 100% speed and with 25% load is 98.5%. The efficiency of the power module at 25% speed and with 100% load is 96.8%. The efficiency of the power module at 25% speed and with 25% load is 94%. The efficiency of the drive, including the motor, is typically 87%. The service factor is 1.0. The maximum load is 150% for one minute or 200% for 5 seconds. The operator’s speed adjustment is 0 to the rated speed. The specification speed range is 100:1, based on the top speed and the tachometer.
