Product Description:

The FC-202P4K0T4131B8920 is a variable frequency inverter manufactured by Danfoss for the VLT FC 202 AQUA Drives series. The drive accepts industrial three-phase power and generates a programmable output that allows automation controllers to adjust pump or fan speed instead of relying on throttling valves. This electronic regulation improves process stability while limiting wear on rotating equipment in water treatment facilities and other liquid-handling systems.

Its power stage is designed for a 380–480 VAC grid and draws a continuous 7.4 A from feeders operating at 441–480 V. The inverter can supply a motor with a continuous output current of 8.2 A. Apparent power reaches 6.9 kVA at 400 V and 6.5 kVA at 460 V, which supports appropriate transformer and busbar sizing. Overall conversion efficiency is 0.97, resulting in modest thermal losses during normal operation. During brief overloads, the input bridge tolerates 11.1 A, and the output stage can deliver 12.3 A so pumps can accelerate against static head. The three-phase power architecture balances loading across the supply conductors.

The drive supports an adjustable output frequency of up to 590 Hz, allowing compatible motors to operate across a broad speed range. Shielded motor leads can extend up to 150 m, while unshielded leads can extend up to 300 m without exceeding the stated voltage-rise limits. Heat generation at the rated load is limited to 124 W, which reduces the ventilation demand inside the control panel. The maximum prefuse rating is 20 A, providing coordination with upstream circuit protection. The continuous power rating is 4.0 kW, and the associated terminals accept conductors with cross-sectional areas of up to 4 mm². Disconnect links may use 6 mm² copper conductors, matching common installation practices for water-industry equipment.
