Product Description:

The FC-202P2K2T2131X9644 is an AC variable frequency drive from Danfoss that belongs to the VLT FC 202 AQUA Drives series. Designed for pump and fan applications in water and wastewater plants, the unit converts a fixed three-phase mains supply into a variable-frequency output so that centrifugal loads run only as fast as the process demands. By integrating speed control, it can reduce energy consumption, limit hydraulic shocks, and extend the mechanical service life of connected equipment.

At 208 V, the power stage can deliver 3.82 kVA of continuous apparent power, providing an output capability of 2.2 kW for typical induction motors. The inverter supplies a continuous current of 10.6 A, allowing it to power a 3.0 HP pump without thermal derating. Electrical efficiency reaches 0.96, indicating that approximately 4% of the incoming energy is lost under the applicable operating conditions; the estimated power loss is 116 W. The control platform modulates the output frequency up to 590 Hz, permitting high-speed operation of specialized motors when required. For short-circuit protection, the line side is coordinated with a 20 A fuse, and the input section draws a maximum of 9.5 A from a 200–240 VAC three-phase source.

The drive can operate at temperatures up to 50 °C and at installation heights up to 1000 m without output derating. It tolerates a phase imbalance of 3.0% and supports shielded motor leads as long as 150 m, providing flexibility when the drive and pump are installed in separate locations. Acceleration and deceleration ramps can be extended to 3600 s, which allows gradual speed changes that can help prevent water hammer in large pipelines. The IE2 efficiency class supports energy-efficient operation, while protective algorithms help maintain stable performance across varying loads on a 200–240 VAC network.
