Product Description:

The FC-202PK37T4134F6398 is a compact drive module produced by Danfoss for the VLT FC 202 AQUA Drives series. It modulates electrical input to match the torque and speed requirements of small pumps and blowers in water-treatment and distribution lines, supporting tighter flow control and lower energy consumption in automated facilities. By integrating the drive at the motor location, machine builders can reduce mechanical throttling components and simplify control panel layouts.

During steady operation at 460 V, the drive delivers a continuous apparent power of 0.9 kVA, corresponding to a phase output current of 1.2 A. The displacement power factor is greater than 0.98, so most of the drawn current performs useful work rather than circulating reactive power. Conversion efficiency is measured at 0.93; the remaining losses appear as heat, quantified at only 35 W. A supply frequency of 50/60 Hz with a +4/-6% tolerance lets the unit track common utility variations without parameter adjustments. These electrical values enable precise motor control while keeping feeder size modest for small pumping skids.

The motor shaft output is rated at 0.50 HP, which corresponds to a mechanical power of 0.37 kW for fractional-kilowatt installations. The drive accepts three-phase mains between 380–480 VAC without derating when installed up to 1000 m above sea level and exposed to ambient air temperatures as high as 50 °C. Field wiring can use motor or line conductors up to 4 mm², and shielded motor cable runs may extend to 150 m to reach submerged or distant pump sets. Upstream protection can use time-delay fuses or circuit breakers rated no higher than 10 A, matching the 1.0 A input draw and preventing nuisance trips during startup. The drive operates exclusively on three-phase power and synchronizes its internal pulse-width-modulated output with the control system for consistent regulation in water-processing machinery.
