Product Description:
The FC-202P5K5T4131X7797 is a variable-frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. As a member of the VLT AQUA Drive product group, it modulates the speed of centrifugal pumps and fans used in water supply, irrigation, and wastewater treatment lines. By converting fixed-frequency three-phase mains power into variable-frequency output, the unit permits energy-efficient flow control and protects pipes and mechanical equipment against pressure shocks common in fluid-handling applications.
The rated output power is 5.5 kW, which corresponds to a mechanical shaft capability of 7.5 HP. The drive accepts a three-phase input of 380–480 VAC, and its conversion efficiency reaches 0.97 at full load, reducing the heat released into the cabinet. Power factor correction is high; the displacement power factor is >0.98, while the true power factor remains at least 0.9, reducing reactive current on the supply. Two analog inputs receive speed or pressure references, and a 30 A upstream fuse limits fault energy. The permitted phase imbalance is 3.0%, which helps protect the input rectifiers from uneven loading. For controlled braking, the drive uses a resistor rated at 113.3 Ω nominal and 99 Ω minimum to match the thermal capacity of the integrated brake chopper.
Operation is permitted at ambient temperatures up to 50 °C and elevations up to 1000 m without derating, making the drive suitable for most plant rooms and outdoor equipment enclosures. Shielded motor leads can extend to 150 m, allowing the drive to be installed away from wet areas while maintaining electromagnetic compatibility. The integrated brake chopper supports a duty cycle of 7%, allowing moderate energy dissipation during controlled deceleration when paired with the required braking resistor.
