Product Description:

The FC-202P4K0T6131G9766 is an AC variable frequency drive produced by Danfoss within the VLT FC 202 AQUA Drives series. Designed for in-line mounting in control panels, the device modulates voltage and frequency on three-phase circuits so centrifugal pumps and axial-flow fans deliver only the flow required by water and wastewater processes. Its control algorithms support low-speed efficiency and resonance avoidance, making it suitable for municipal plants and commercial HVAC pumping stations.

When supplied from a 525–550 V network, the drive has an apparent power demand of 6.1 kVA, a value that guides transformer and generator sizing. Within the same voltage range, its continuous output current reaches 6.4 A, establishing cable ampacity and thermal limits at the motor terminals. Conversion efficiency is rated at 0.97, so approximately three percent of the incoming energy becomes heat that the enclosure must dissipate. This residual heat equates to an estimated power loss of 145 W during rated operation. The inverter has a maximum output frequency of 590 Hz, allowing compatible high-speed motors to operate without mechanical gearing.

The power section has an output rating of 5.0 HP, equivalent to 4.0 kW, providing adequate capacity for moderate pump impellers. The control electronics tolerate ambient temperatures up to 50 °C and noncondensing relative humidity as high as 95%, so enclosure climate requirements remain modest. Shielded motor leads may extend to 150 m, while unshielded leads may extend to 300 m, supporting distributed equipment layouts without intermediate reactors. The three-phase input draws no more than 5.8 A and is protected by a 20 A prefuse, while the power and disconnect terminals accept 4 mm² and 6 mm² conductors, respectively, to simplify wiring.
