Product Description:
The FC-202P75KT4131F1079 is an AC variable-frequency drive produced by Danfoss and assigned to the VLT FC 202 AQUA Drives series. Designed for pump and fan duties, the unit modulates motor speed to match real-time flow or pressure requirements in water and wastewater automation. By converting three-phase mains power into a controlled output waveform, it supports energy savings and smooth starts while maintaining compatibility with the broader VLT AQUA Drive product group.
The drive accepts a supply window of 380 - 480 VAC, drawing 118 A at its rated operating point. Through its insulated-gate converters, it provides 130 A of phase-balanced output current, producing up to 103.6 kVA of apparent power for the connected motor. The power section is sized for a continuous mechanical delivery of 75 kW, equivalent to 100 horsepower, allowing centrifugal pumps to maintain high flow without external step-up gearboxes. Voltage, current, and power ratings inform feeder breaker sizing, cable cross-section, and enclosure ventilation, ensuring that upstream protection devices and heat sinks remain within their allowable temperature rise during constant-torque or quadratic-torque duty cycles.
Additional limits define safe field installation. The control permits an overload of 143 A for short acceleration bursts, and total drive losses remain at 1500 W when running at the catalog efficiency of 0.98. Ambient operation is allowed up to 50 °C and to altitudes of 1000 m without derating; sites up to 3000 m require current reduction. Humidity can reach 95% non-condensing, supporting placement in pump rooms or filter galleries. Motor leads may extend to 150 m when shielded, doubling to 300 m for unshielded cable, so the electronics can stay outside splash zones while still controlling submerged or remote pump assemblies.
