Product Description:

The FC-202P1K5T4131L5441 is an AC variable frequency drive manufactured by Danfoss within the VLT FC 202 AQUA Drives series. Designed for pump and fan duties in water-handling installations, the drive converts three-phase mains power into a regulated output that lets control systems match motor speed to process demand. By modulating frequency and voltage, it improves energy efficiency and reduces mechanical stress on centrifugal equipment in municipal or industrial automation environments.

The drive delivers a nominal power rating of 1.5 kW, equivalent to 2.0 HP, so it suits small-frame induction motors commonly found in booster sets. On a 441–480 V supply, the inverter can provide a continuous motor current of 3.4 A, while the input circuit draws up to 3.1 A; these values guide cable sizing and thermal calculations for switchgear. Output frequency can be adjusted from zero up to 590 Hz, allowing oversynchronous operation where high pump speeds are required. The mains voltage range of 380–480 VAC supports global three-phase grids, and a 10 A prefuse protects the input rectifier against line faults. Motor leads may be routed up to 300 m unshielded or 150 m shielded without additional filters.

Energy performance is emphasized by an efficiency of 0.97; at full load, the electronics dissipate only 62 W, permitting installation in compact panels with limited ventilation. Reliable service is maintained at ambient temperatures up to 50 °C, and no derating is required at site elevations up to 1000 m. The control board refreshes parameters every 5 ms, enabling tight feedback loops for pressure or level regulation. Power terminations accept conductors from 0.2 mm² to 4 mm², allowing the frame to accommodate a range of standard power wiring. Motor-side noise is minimized by the drive’s built-in algorithms, allowing long cable runs without reflected-wave stress on stator insulation.
