Product Description:
The FC-202P55KT4131F6654 is a variable frequency drive built by Danfoss for the VLT FC 202 AQUA Drives series. It belongs to the VLT AQUA Drive product group and is intended to modulate the speed of three-phase induction motors in water and wastewater installations. By adjusting motor frequency, the unit matches pump or blower output to process demand, lowering energy use and mechanical stress while accepting mains supplies from 380 to 480 VAC.
Under normal duty, the drive delivers 75 hp, and its electrical conversion operates at an efficiency of 0.98, so only 2% of the input power is dissipated as heat. The control stage can vary the motor speed up to 590 Hz, allowing high-speed impeller operation when required. With a 480 V source, the inverter supplies a continuous output current of 105 A while drawing 95 A from the line. Its apparent power demand is 83.7 kVA at 460 V. These ratings help determine the transformer capacity and cable sizes needed in a panel. The drive tolerates a phase imbalance of up to 3%, helping maintain stable operation on uneven utility feeds. Normal-duty power loss is 1083 W, which must be removed through enclosure ventilation.
The normal-duty power rating is 55 kW, and a high-overload mode is available at 45 kW for applications that need additional starting torque. Line protection is provided by a maximum pre-fuse rating of 160 A. Acceleration and deceleration can be configured with ramp times of up to 3600 s, permitting gradual pressure changes that help protect pipes and valves. Analog feedback circuits can drive loads as low as 500 Ω. Digital outputs can source up to 40 mA at frequencies of up to 32 kHz for contactor or counter tasks. The drive uses a three-phase power topology suitable for controlling compatible induction motors.
