Product Description:

The FC202P1K5T4134L0938 is an AC variable-frequency drive produced by Danfoss within the VLT FC 202 AQUA Drives series. It converts fixed-frequency three-phase power into a variable output that lets pump and blower motors match flow demand in water treatment and other fluid-handling tasks. By delivering speed regulation electronically, the drive reduces valve-throttling losses and supports precise process control inside automated installations.

Rated shaft power is 1.5 kW, so the inverter is sized for small to midrange centrifugal pumps. At 380–440 V, it can provide a continuous motor current of 4.1 A, while the corresponding input draw is 3.7 A; both values decrease when the supply rises toward 480 V. The output section switches at up to 32 kHz, allowing low-noise operation with modern high-efficiency motors. Overall drive efficiency reaches 0.97, meaning only 3% of the supplied energy is lost as heat; the residual power dissipation is 62 W. Thermal load is therefore modest for a 2.7 kVA frame, and standard cabinet ventilation is often sufficient. An 8-bit analog output with a minimum load resistance of 500 Ω enables basic process feedback to external controllers, while a continuous output current of 3.4 A supports installations operating from 441–480 V.

Control wiring tolerates field voltages of up to 28 V DC at the digital input terminals, and each digital output can source up to 40 mA for relays or indicator lamps. To protect upstream circuits, the mains side should be fused at 10 A. Power conductors can have a maximum cross-sectional area of 4 mm², while conductors used with disconnect links may increase to 6 mm² when long cable runs require lower resistance. These connection limits help prevent excessive voltage drop and support secure termination at the drive. The available analog and digital interfaces allow the unit to exchange operating signals with external process-control equipment.
