Product Description:

The FC-202PK37T2135N4878 is a variable frequency drive produced by Danfoss within the VLT FC 202 AQUA Drives series. It modulates three-phase power to regulate centrifugal pumps, blowers, and similar water-handling equipment, delivering accurate speed control while limiting hydraulic transients and energy use in industrial automation. Galvanic isolation in the control card helps protect the logic section from interference during high-frequency carrier operation.

This model accepts a mains supply of 200–240 VAC and converts it into a continuously adjustable output. The output switching frequency can be raised to 32 kHz for quiet motor operation. The inverter has a continuous power rating of 0.37 kW, which corresponds to 0.50 HP when driving standard induction motors. The drive provides one analog output with 0/4–20 mA signaling and supports loads down to 500 Ω, allowing direct connection to most SCADA or PLC analog input cards. Two digital transistor outputs transmit running, fault, or process status signals. These interfaces allow the drive to report operating conditions to external control equipment without requiring separate signal converters.

Continuous operation is permitted at ambient temperatures up to 50 °C, provided the installation altitude remains at or below 1000 m. Derating extends operation to altitudes of up to 3000 m when necessary. Motor leads may reach 150 m when shielded or 300 m when unshielded, with the shielded limit of 150 m helping maintain electromagnetic compatibility. Start-up at full load is possible from 0 °C, and the electronics support reduced-load operation down to -10 °C. The drive handles three-phase power natively and belongs to the VLT AQUA Drive product group under series identifier 202.
