Product Description:

The FC-202P7K5S4131Z3884 is a variable frequency drive produced by Danfoss as part of the VLT FC 202 AQUA Drives series. Designed for pump and fan duties, the unit converts fixed-frequency mains power into a regulated output frequency so motor speed can match real-time flow requirements in water treatment and distribution processes. By integrating speed control and motor protection in a single compact package, the drive simplifies installation within industrial automation panels dedicated to liquid-handling equipment.

Rated at 7.5 kW, the drive supplies enough electrical power for midsized centrifugal pumps while operating from a three-phase input of 380–480 VAC. On 380–440 V lines, it can deliver a continuous motor current of 16 A, which establishes the thermal limit for steady operation. Electrical conversion efficiency reaches 0.96, meaning approximately 4% of the input energy is dissipated as heat; under full load, this corresponds to an internal loss of 300 W. The internal DC link is protected by a 63 A pre-fuse sized to interrupt fault currents before bus components are overstressed.

Short-duration overloads are handled with an intermittent output rating of 17.6 A, providing extra torque during pump acceleration without exceeding semiconductor limits. The output rating of 10 HP is suitable for typical 6- and 8-pole motors used in municipal pumping stations. Operating limits support continuous service at ambient temperatures up to 50 °C and elevations up to 1000 m without derating. A maximum relative humidity of 95% and conformal-coated electronics allow installation in humid pump galleries. Motor leads can be run up to 150 m when shielded or 300 m when unshielded, and the terminals accept conductors up to 10 mm², supporting suitably sized wiring for long cable runs.
