Product Description:
The FC-202P11KT2131Z3886 is a variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. Designed for centrifugal pumps, blowers, and filtration fans, it regulates motor speed instead of relying on throttling, which can reduce energy use in water and wastewater plants. The unit operates on three-phase 200–240 VAC mains and handles a continuous apparent power of 16.6 kVA, making it suitable for mid-range pump motors. Its speed control also helps the connected equipment respond to changing flow or pressure demands without requiring continuous mechanical adjustment.
A continuous output current of 46.2 A supports sustained full-duty operation, while the power rating of 11 kW matches common IEC-frame induction motors. Overall conversion efficiency reaches 0.96, so 514 W is dissipated as heat under nominal load. The rectifier draws a maximum input current of 42.0 A, and branch protection is provided by a 63 A pre-fuse. Momentary load changes can be accommodated because the inverter delivers an intermittent output current of 50.8 A. These electrical values assist with the selection of upstream circuit breakers and motor protection devices. The stated heat dissipation also provides a basis for establishing suitable airflow and temperature control within an enclosure.
The supply line has a frequency rating of 50/60 Hz, allowing operation with either common grid frequency. Two analog inputs are scanned at a 10-bit resolution to accept setpoints from level transmitters or differential-pressure sensors. One analog output reproduces speed or load data for plant monitoring, allowing operating information to be sent to an external control or display system. Two programmable digital outputs can switch solenoids or relays, and their maximum switching speed is 32 kHz, which supports pulse-frequency control when compatible equipment is connected. These control resources allow the drive to process sensor signals, regulate pump operation, and transmit operating data without requiring separate signal-conversion hardware.
