Product Description:

The FC-202P5K5T2131F8207 is a variable-frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. It modulates the speed of centrifugal pumps and blowers in water and wastewater applications, adapting motor torque to fluctuating system demand. Its control functions include PID regulation, sleep mode, and pipe-fill routines, while series code 202 identifies the associated hardware platform. These functions allow the drive to respond to changing flow and pressure requirements without relying on continuous full-speed motor operation.

The inverter delivers a motor output of 5.5 kW, which is equivalent to 7.5 HP, while drawing a nominal input current of 22.0 A and supplying up to 24.2 A on the output side. It connects to 200–240 VAC mains, and the incoming supply must be protected by a 63 A pre-fuse. A conversion efficiency of 0.96 limits heat generation during normal operation. The control stage can raise the fundamental frequency until the motor terminals receive a maximum frequency of 590 Hz. Power is processed through a six-pulse topology that requires balanced three-phase power and supports automatic derating if the voltage moves outside the permitted tolerance.

The drive supports a continuous apparent power of 8.7 kVA and produces a thermal power loss of 310 W that must be removed through panel ventilation. It can operate in ambient temperatures up to 50 °C without current reduction when the installation altitude does not exceed 1,000 m. Operation is permitted at altitudes up to 3,000 m when airflow and loading are adjusted according to the applicable derating requirements. Shielded motor cables may extend up to 150 m, while unshielded motor cables may extend up to 300 m, providing routing flexibility in large pump rooms. The drive allows no more than two power-ups per minute to prevent excessive capacitor stress from frequent cycling.
