Product Description:

The FC-202P7K5T6134G2999 is an AC variable frequency drive produced by Danfoss within the VLT FC 202 AQUA Drives series. It is built to modulate pump and fan motors in water supply and treatment plants, allowing process controllers to adjust flow while minimizing energy use. By varying the output frequency instead of throttling mechanical valves, the unit helps maintain system pressure, reduce water hammer, and extend equipment life in industrial fluid-handling applications.

At a nominal rating of 7.5 kW, the inverter supplies mechanical power equivalent to 10 HP for medium-sized centrifugal pumps. When connected to a 525–550 V network, it delivers a continuous output current of 11.5 A, matching the torque demand of typical IE2 motors. Electrical conversion efficiency reaches 0.97, so only 3% of the incoming energy is lost as heat during steady operation. Because the input section is designed for three-phase power, the drive interfaces directly with common 525–600 V industrial feeders, eliminating the need for step-up transformers and supporting balanced line loading. These electrical characteristics help determine the requirements for upstream switchgear and downstream motor windings.

The housing supports full current at ambient temperatures up to 50 °C, allowing installation in pump rooms without air conditioning. The drive can operate at altitudes up to 1000 m without derating, which covers most municipal sites. The accepted line voltage reaches a maximum of 600 VAC, allowing the power stage to operate on high-voltage industrial supplies. During operation, the heat sink dissipates 261 W, which should be considered when planning panel ventilation. Shielded motor cables can reach 150 m, while unshielded motor cables can reach 300 m. Upstream circuit protection can be provided by a 32 A gG fuse.
