Product Description:
The FC-202P37KT6131G4331 variable frequency drive is produced by Danfoss within the VLT FC 202 AQUA Drives series. The unit controls the speed of centrifugal pumps and blowers in water-handling systems by converting fixed-frequency line power into an adjustable three-phase output. Its closed-loop motor control allows flow to be matched to system demand while reducing energy consumption and mechanical stress on piping and connected equipment. This control method is suited to applications that require stable pressure during changing flow conditions. Programmable operation also helps the drive respond smoothly when pumps start, stop, or encounter changing process loads.
The drive operates on 525–600 V AC three-phase utility power. At 575 V, it draws 47 A of line current while supplying a continuous motor output of 37 kW, which corresponds to 50 HP. Apparent power demand at this voltage is 51.8 kVA, and the output terminals can deliver 52 A continuously. The conversion efficiency is 0.98, which limits heat generation inside the enclosure during normal operation. Its synthesized output frequency ranges from 0–590 Hz, supporting low-speed priming and overspeed flushing cycles. Output voltage can be adjusted from 0 to 100% of the incoming supply voltage. Programmable acceleration and deceleration ramps range from 1 to 3600 seconds, allowing pressure transients to be controlled in sensitive distribution networks.
For short surge events, the inverter supports 57 A of intermittent current, allowing it to accommodate brief start-up loads or sudden valve movement without immediately activating current protection. The upstream circuit can use a maximum fuse rating of 100 A. Shielded motor cables up to 150 m long can be installed without exceeding the drive’s carrier-frequency limits. The installation area may have up to 95% noncondensing humidity and an ambient temperature of 50 °C. Derating is required when applicable operating limits are exceeded, including installations approaching the maximum altitude of 3000 m. The three-phase design distributes electrical loading across all supply phases and supports balanced operation in water-handling systems.
