Product Description:
The FC-202P18KT2131B9273 is an AC variable-frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. It regulates induction motor speed in pump and blower systems used in water and wastewater treatment, allowing process controllers to match flow to changing demand while reducing unnecessary energy consumption. Its variable-speed output can regulate flow without relying solely on valves, dampers, or other mechanical throttling methods, which helps limit stress on connected equipment.
The drive provides a continuous shaft output of 18.5 kW, equivalent to 25 HP, from a three-phase mains supply rated at 200 to 240 VAC. The input section draws a continuous 68.0 A, while the inverter stage delivers a continuous 74.8 A to the motor. An efficiency of 0.97 reduces waste heat and limits the ventilation burden inside the control cabinet. A maximum pre-fuse rating of 125 A provides upstream circuit protection when coordinated with suitable conductors and protective devices. The three-phase power connection supports installation on common low-voltage industrial networks. Two analog inputs accept 0–10 V or 4–20 mA process signals for speed references and feedback adjustments. During intermittent loading, the output current can rise to 82.3 A to support acceleration when large centrifugal pumps start under pressure.
The inverter dissipates 737 W at rated load, and reliable operation is maintained at ambient temperatures up to 50 °C. Conformal-coated electronics tolerate relative humidity levels up to 95% without condensation, making the drive suitable for installation near water-processing equipment when appropriate enclosure practices are followed. The drive can be mounted at altitudes up to 1,000 m without current derating. Shielded motor cable can extend up to 150 m, while unshielded motor cable can extend up to 300 m before additional output filtering is required. These cable allowances provide flexibility when the motor and control cabinet must be installed in separate areas of a facility. The thermal limits and coated electronics support sustained pump and blower operation under demanding industrial conditions.
