Product Description:

The FC-202PK55T2134F6387 is an AC variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. In pumping and aeration applications, it modulates the speed of three-phase induction motors, allowing flow or pressure to be matched to process demand while reducing energy use and mechanical stress in water-handling equipment throughout industrial automation. As part of the VLT AQUA Drive product group, it is intended for centrifugal pumps, blowers, and similar loads that do not require constant torque.

For electrical connection, the drive accepts a mains voltage range of 200–240 VAC with three-phase power, making it suitable for low-voltage pump installations. Under rated conditions, the input draws 3.2 A, and the drive delivers a continuous output current of 3.5 A, equivalent to 1.26 kVA at the terminals. Its motor output is rated at 0.55 kW, which corresponds to 0.75 HP. When process demand increases, the converter tolerates 4.8 A on the supply side and 5.3 A on the motor side for short intervals without derating. The output frequency can be increased continuously to 590 Hz, allowing compatible high-speed induction motors to operate beyond the standard 50 or 60 Hz range when required.

The electrical protection path accommodates a 10 A upstream fuse, and outgoing wiring can be terminated on 6 mm² disconnect links while the motor leads fit 4 mm² lugs. Installations may use up to 150 m of shielded cable or 300 m of unshielded cable without exceeding the drive-side voltage-drop limits, providing flexibility when pumps are located far from the control enclosure. Conversion efficiency reaches 0.95, placing the unit in the IE2 energy-efficiency class and limiting full-load power loss to 42 W. The internal thermal design supports continuous operation at ambient temperatures up to 50 °C, which helps simplify enclosure ventilation and cooling arrangements.
