Product Description:
The FC-202P37KT2131H2225 is an AC variable-frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. It converts fixed-frequency mains power into a controlled output for regulating the speed and torque of compatible AC motors. This functionality allows plant controllers to adjust centrifugal pump or blower speed according to process demand rather than relying on mechanical throttling. Typical applications include municipal lift stations, filtration systems, water-treatment equipment, and other automated processes that require controlled fluid flow or air movement.
The inverter supports a motor output of up to 50 HP, making it suitable for medium-sized pump and blower motors. Its corresponding electrical output rating is 37 kW, which can be used when selecting compatible motors, conductors, overload protection, and related power components. The input section accepts 200 to 240 VAC, allowing connection to an appropriate low-voltage distribution system without a step-down transformer. Operation with three-phase power distributes the electrical load across three conductors and helps the connected induction motor produce smooth torque. The drive modulates motor voltage and frequency in response to control commands, allowing pump output to follow changes in pressure, level, or flow demand.
An integrated RFI filter attenuates conducted electrical emissions on the line side. This filtering helps reduce interference with nearby instruments used to monitor flow rate, pressure, water quality, or other process conditions. The series identifier 202 places the model within a platform that uses compatible enclosure arrangements, keypad layouts, software menus, and option-board formats. The drive supports variable-torque pump control, which suits centrifugal loads whose torque demand changes with operating speed. Pump-clean and sleep functions can support water-processing applications by clearing obstructions when needed and reducing unnecessary motor operation during periods of low demand.
