Product Description:

The FC-202PK55T2131N2367 is an AC variable frequency drive developed by Danfoss for its VLT FC 202 AQUA Drives series. As part of the VLT AQUA Drive product group, it is intended for pump and fan duties where precise speed regulation supports water and wastewater processes. By modulating the stator frequency, the unit maintains motor torque while trimming energy consumption throughout variable-flow applications. Within an automation panel, it provides torque control, soft starting, and integrated protection for centrifugal loads. The manufacturer positions it as a compact controller that interfaces directly with standard three-phase mains and upstream PLC logic.

Electrically, the drive accepts three-phase supply lines between 200 – 240 VAC and delivers a nominal shaft power of 0.55 kW, which equates to 0.75 HP for users working in imperial units. Under rated load, its inverter section handles 1.26 kVA of apparent power and supplies up to 3.5 A of continuous output current while drawing 3.2 A from the mains. The topology sustains a true power factor of at least 0.9 and an efficiency of 0.95, minimizing line distortion and excess heat. A 10 A prefuse protects the branch circuit, and 4 mm² power conductors connect the unit to the distribution bus.

Installation requirements include conductor sizing and operating limits. Control wiring is isolated through a 6 mm² disconnect loop, and the output can be routed through shielded motor cable up to 150 m without violating EMC limits. Thermal headroom is provided by a maximum ambient temperature of 50 °C, while enclosure losses remain at 42 W, supporting cabinet ventilation calculations. Reactive performance is supported by a displacement power factor greater than 0.98, and the drive carries the high-efficiency classification of IE2.
