Product Description:
The FC-202P55KT4131F1099 is an AC variable frequency drive produced by Danfoss within the VLT FC 202 AQUA Drives series. The unit modulates three-phase mains power to regulate the speed of centrifugal pumps and blowers in water and wastewater plants, allowing process controllers to adjust flow without mechanical throttling. Its control algorithms support energy-efficient motor operation and stable pressure in municipal lift stations, filtration lines, and irrigation booster systems. Variable-speed control also reduces the mechanical stress associated with abrupt motor starts and unnecessary operation at full speed.
The drive accepts 380 - 480 VAC from a three-phase power supply and can deliver 55 kW of mechanical output. On 380–440 V lines, the continuous input demand is 96 A, and the inverter supplies 106 A to the motor. At 441–480 V, the corresponding input and output currents decrease slightly to 95 A and 105 A. These currents correspond to apparent power values of 73.4 kVA at 400 V and 83.7 kVA at 460 V, which are useful when sizing upstream transformers and conductors. Conversion efficiency reaches 0.98, so only a small portion of the incoming energy is dissipated as heat during normal operation.
The drive dissipates 1100 W at maximum load and can operate at ambient temperatures up to 50 °C when adequate airflow is available. It can be installed at elevations up to 1000 m without derating, and the permitted relative humidity reaches 95 percent under noncondensing conditions. A 160 A upstream fuse provides protection against short-circuit events. Shielded motor leads can extend up to 150 m, while unshielded leads can extend up to 300 m. These cable allowances permit pumps in remote locations to be powered from centralized switch rooms. Proper cable selection and routing help control reflected voltage at the motor terminals on longer runs. Adequate enclosure ventilation is necessary to remove generated heat and maintain the permitted operating temperature.
