Product Description:

The FC-202PK75T4134F6404 is a variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. It converts fixed-frequency three-phase mains power into a regulated output that controls the speed of centrifugal pumps, blowers, and other water-handling machinery. Matching motor speed to process demand improves system stability and reduces energy consumption, particularly when a pump operates below its maximum capacity for extended periods. The drive also provides functions for fluid applications, including sleep mode, dry-run detection, and flow compensation.

The unit is rated for a mechanical output of 0.75 kW, corresponding to the 1 HP class of pump motors commonly used on auxiliary loops. It accepts a three-phase supply ranging from 380 to 480 VAC and provides an output frequency ranging from 0 to 590 Hz, allowing speed regulation beyond the motor’s synchronous base frequency when the application permits it. The drive supports a continuous output current of 2.4 A, providing steady operation under its rated load. Its efficiency rating is 0.96, which means approximately four percent of the electrical input is dissipated as heat under nominal operating conditions.

The electronics can operate at ambient temperatures up to 50 °C, while internal power loss is limited to 46 W. These thermal values allow the drive to use convection or light forced-air cooling in most suitable control cabinets. The incoming feeder requires a fuse or circuit breaker with a maximum rating of 10 A, and the rectifier draws 2.2 A at the minimum supply voltage. Output voltage varies from zero to the full mains voltage and can be delivered through shielded motor cables up to 150 m long. The terminals support conductors up to 4 mm², and the drive provides 1.7 kVA of apparent power at a mains frequency of 50 or 60 Hz.
