Product Description:

The FC-202P22KT2131F0998 is an AC variable frequency drive built by Danfoss and supplied as part of the VLT FC 202 AQUA Drives series. The unit is used to regulate centrifugal pumps, blowers, and other water-handling motors in automated fluid systems. By adjusting motor speed in response to process feedback, the drive reduces energy consumption and mechanical stress while keeping flow and pressure within required tolerances.

With a 208 V supply, the inverter delivers a continuous apparent power of 31.7 kVA, which corresponds to a steady output current of 88.0 A at the motor terminals. Conversion efficiency reaches 0.97, so only 3% of input energy is dissipated as heat during nominal loading. The integrated motor table supports applications up to 30 HP, and the input section accepts a mains range of 200–240 VAC on a three-phase network. These ratings enable constant-torque control over the full speed range while limiting supply demand. Two analog inputs accept either 0/4–20 mA or 0–10 V signals, allowing direct connection of pressure transducers or potentiometers. One analog output provides a 0/4–20 mA feedback signal for remote indicators.

The supply side can draw up to 80.0 A during transient loading, so branch protection must be coordinated with a 125 A semiconductor fuse or circuit breaker. Internally, the inverter’s output stage modulates carrier pulses at up to 32 kHz, providing fine resolution for low-noise pump operation. Its power module is rated for 22 kW, matching the stated horsepower limit when the system operates on a 60 Hz grid. Control wiring includes four discrete inputs that can be expanded to six for start, stop, and PID override functions, along with two relay outputs for status signaling. The Series 202 code supports identification within plant inventories, while the combination of current-loop and voltage inputs provides compatibility with common field instruments and transmitters.
