Product Description:

The FC-202P7K5T4131X5736 is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. Designed for pump and blower duties in irrigation, wastewater, and filtration skids, the unit converts fixed mains power into a modulated output that matches real-time flow demand. By adjusting motor speed instead of throttling valves, it supports energy-efficient process control across municipal and industrial water applications.

The drive delivers a continuous mechanical output of 7.5 kW, which corresponds to 10 HP. It accepts a three-phase supply voltage of 380 to 480 VAC and draws an input current of 14.4 A in the 380 to 440 V range. On the output side, it can supply up to 16 A to the motor terminals, while a limit of 14.5 A applies when the mains voltage exceeds 441 V. The drive has an efficiency of 0.97, meaning three percent of the incoming power is lost as heat under nominal load. A 30 A semiconductor fuse or equivalent upstream protection safeguards the inverter against short-circuit events. The internal terminals accommodate motor cable cross sections up to 4 mm². The platform connects directly to standard three-phase plant distribution without step-up transformers or single-phase adapters.

Total power dissipation is 225 W, a value that helps determine enclosure ventilation requirements. The electronics remain functional at ambient temperatures up to 50 °C. Full output current is available at elevations not exceeding 1000 m without derating. Conformal coating and gasketed airflow paths permit operation at up to 95% noncondensing relative humidity. For long motor runs, shielded cable can extend to 150 m, while unshielded cable may reach 300 m. These cable limits help keep reflected-wave voltage within the motor insulation rating. Control wiring with a cross section of up to 6 mm² can be connected to the disconnect terminals, preserving the required clearances inside compact pump panels.
