Product Description:

The FC-202P1K1T4131B8894 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. In pump or fan installations, the unit modulates motor speed to match real-time flow demand, lowering energy consumption and mechanical stress on hydraulic components. Integration into three-phase power distribution makes the drive suitable for water-treatment skids, irrigation pumping stations, and building services where automated flow regulation is required.

This model delivers a nominal shaft output of 1.1 kW, equivalent to 1.5 HP, so it supports small to mid-sized centrifugal pumps typically found in booster sets. It accepts an input voltage range of 380–480 VAC and converts that supply into a pulse-width-modulated waveform with a peak efficiency of 0.96. This high efficiency minimizes heat generation inside control panels. The remaining electrical losses are 58 W under rated load, which is useful when determining cabinet ventilation requirements. A 10 A gG fuse can provide upstream protection while allowing modest conductor sizes for compact installations.

The inverter’s switching stage supports carrier frequencies up to 32 kHz, providing flexibility when balancing acoustic noise against motor heating. An output current of 2.7 A is maintained without derating at ambient temperatures up to 50 °C, provided airflow around the heat sink remains unobstructed. Full-power operation is also permitted at elevations up to 1000 m; above this height, the drive must be current-limited to compensate for reduced air density. The control electronics include one analog output that can drive 500 Ω feedback loops and digital outputs rated at 40 mA for relay interfacing. Terminal blocks accommodate 6 mm² mains conductors and 4 mm² motor leads, enabling straightforward field wiring.
