Product Description:
The FC-202P1K5T4131G1977 is a variable frequency drive produced by Danfoss and supplied under the VLT FC 202 AQUA Drives series. In pumping, aeration, and filtration systems, it adjusts induction motor speed to maintain flow or pressure while reducing energy consumption. The unit belongs to the VLT AQUA Drive product group and carries the internal 202 identifier. Its format supports installation in water-industry control panels that use compatible Danfoss electrical and mechanical layouts.
The inverter accepts 380–480 VAC three-phase power and converts it into a modulated output for a rated shaft load of 1.5 kW. This output corresponds to 2.0 HP, making the drive suitable for process pumps and booster fans within that power range. At 380–440 V, the drive can deliver a continuous motor current of 4.1 A, while operation at higher supply voltages permits 3.4 A. The apparent power ratings are 2.8 kVA at 400 V and 2.7 kVA at 460 V. Conversion efficiency reaches 0.97, so only a small portion of the input power is lost as heat. The corresponding input currents are 3.7 A and 3.1 A, supporting motor operation across the stated voltage range.
Heat produced during full-load operation is 62 W, which can be removed through standard control-panel ventilation. Upstream protection may use a circuit breaker rated up to 25 A and a pre-fuse rated up to 10 A, with a gG-10 fuse recommended for coordinated fault clearing. The output terminals accept conductors up to 4 mm², while the disconnect side accommodates conductors up to 6 mm². This difference allows the motor and line wiring to use conductor sizes appropriate for their respective terminals. With a five-meter motor cable, the output has a du/dt slope of 0.862 kV/µs. Controlling the voltage rise rate helps reduce electrical stress on the motor insulation during switching operation.
