Internal Product Review

The FC-202P90KT6135N4883 is a Danfoss VLT FC 202 AQUA drive with a 90 kW rating and three-phase power input. High conversion performance comes from 0.98 efficiency, while the 0–590 Hz output frequency gives this drive excellent control range for pump and fan service. A strong choice for process duty, especially where stable operation and energy-conscious performance matter.

Product Description:

The FC-202P90KT6135N4883 is a variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. It is designed for pump, blower, and fan duties in water and wastewater plants. The drive converts fixed supply power into a controlled output that regulates motor speed. This operation allows industrial controllers to adjust flow and pressure in response to real-time process requirements while avoiding unnecessary motor operation at full speed.

For electrical integration, the unit accepts a three-phase supply of 525–600 V AC with a tolerance of ±10% and operates on networks running at 50 or 60 Hz with a tolerance of +4% to −6%. Its inverter section provides 90 kW of continuous power and a steady motor current of 131 A. The available output frequency range is 0–590 Hz, supporting applications that require broad motor-speed adjustment. Operating efficiency reaches 0.98, while the true power factor is at least 0.9. With a 550 V input, the drive draws a maximum current of 124.3 A. Upstream circuit protection uses a 250 A pre-fuse to coordinate protection for the drive and connected power conductors.

Total semiconductor and magnetic power dissipation is 1800 W, so the enclosure must provide sufficient airflow to remove heat during operation. The ambient temperature must remain below 50 °C to prevent excessive thermal loading. On the motor side, the drive can supply up to 125 HP for high-capacity pumping and airflow applications. The DC bus accepts brake or load-sharing conductors with cross-sectional areas of up to 95 mm², allowing connection to compatible external braking or shared-bus equipment. Line and motor terminals accommodate cables as large as 150 mm², providing conductor capacity for installations where cable length and voltage drop require larger wiring.
