Product Description:
The FC-202P37KT6131U7790 is an AC variable-frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. In water and wastewater automation, the unit modulates the speed of three-phase induction motors so pumps and blowers can match changing process demand instead of running at a fixed line frequency. This speed control reduces energy consumption and limits hydraulic stress on pipes, valves, and other system components.
The drive can supply a continuous apparent power of 51.8 kVA, so the upstream switchgear must be sized for that volt-ampere load. At the motor terminals, it delivers a continuous output current of 52 A while drawing a maximum line current of 47 A, so the feeder and circuit breaker must be rated accordingly. The efficiency rating is 0.98, indicating that approximately 2 percent of the input power is lost as heat during nominal operation. A peak output frequency of 590 Hz permits operation with compatible high-speed motors without requiring gearbox stages. The product has an IE2 energy-efficiency classification, aligning it with international efficiency benchmarks for low-voltage drives. Protection coordination is simplified because a 100 A pre-fuse can safeguard the drive input. The unit connects to a three-phase utility power supply.
The drive can be installed at elevations up to 1000 m without derating and at elevations up to 3000 m with an output-current reduction. Ambient air may range from the minimum startup temperature of 0 °C to a maximum of 50 °C, and continuous operation is permitted at 95 percent relative humidity without condensation. Shielded motor cables can extend up to 150 m, while unshielded cables can extend up to 300 m, allowing the drive to regulate remote pump sets. The power section is rated at 37 kW for operating pumps and blowers in large lift-station or treatment-plant systems.
