Product Description:
The FC-202P37KT2131B9314 is a three-phase AC variable-frequency drive produced by Danfoss within the VLT FC 202 AQUA Drives series. Designed for pump and fan applications in water and wastewater plants, the unit regulates motor speed instead of relying on mechanical throttling. This approach provides more precise process control and can reduce energy consumption in fluid-handling systems. Its control functions are designed for the quadratic-torque characteristics associated with centrifugal pumps and fans. Onboard analog and digital outputs send operating status and process data to supervisory PLCs and other external control equipment.
The drive supplies a continuous output current of 143 A, corresponding to 51.5 kVA and a rated motor output of 37 kW. It accepts a line supply of 200–240 VAC and produces an output frequency of up to 590 Hz, supporting specialized centrifugal pumps that operate at high speeds. Its conversion efficiency is 0.97 under nominal operating conditions, limiting the amount of input energy lost as heat. The control card supports an analog feedback load of 500 Ω. Its digital transistor output supplies up to 40 mA, allowing the drive to report operating status to compatible relays, indicators, or controller inputs without additional signal conditioning.
At full load, the drive draws 130 A from the line supply and requires protection from a 200 A time-delay fuse. The power terminals accept copper conductors with cross-sectional areas of up to 150 mm², providing capacity for the required line and motor wiring. Shielded motor cables may extend up to 150 m, while unshielded motor cables may extend up to 300 m without exceeding the stated output filtering limits. The thermal design supports continuous operation at ambient temperatures up to 50 °C. Cabinet ventilation must maintain the permitted air temperature while removing heat generated by the drive during normal operation. Proper conductor sizing, fuse selection, cable shielding, and airflow are necessary to maintain reliable operation at the rated load.
