Product Description:
The FC-202P75KT4131B9534 is an AC variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. In pumping and aeration systems, it regulates induction motor speed so operators can adjust flow or pressure without relying entirely on mechanical throttling. Variable-speed operation can reduce unnecessary motor output when a process requires less than the pump’s full capacity. The drive is suited to water-handling equipment such as supply pumps, circulation systems, treatment basins, and aeration machinery.
The drive accepts a three-phase mains supply between 380–480 VAC and provides a continuous motor output of 75 kW. Its efficiency reaches 0.98, and the unit is assigned to energy-efficiency class IE2. The control system includes two analog inputs for connecting pressure, flow, level, or other process transducers. Each analog output has an 8-bit resolution and can operate with a load of up to 500 Ω, making the outputs suitable for compatible meters, relays, and monitoring devices. The control electronics use 10-bit conversion for command processing, supporting accurate interpretation of incoming reference signals. A maximum upstream fuse rating of 250 A protects the power section against excessive current. These electrical characteristics allow the drive to regulate motor operation while exchanging process signals with external automation equipment.
The digital output supports frequencies up to 32 kHz, while incoming process variables are digitized at a resolution of 10 bits. The drive can operate at ambient temperatures up to 50 °C and in relative humidity levels as high as 95%, provided condensation is prevented. Installation altitude must not exceed 1,000 m when the unit is operated under the stated conditions. Shielded motor cables may extend up to 150 m, while unshielded motor cables may extend up to 300 m. These cable allowances permit the inverter to be installed at a practical distance from pumps located in distributed galleries, equipment rooms, or treatment areas. Proper cable shielding and routing help preserve signal integrity and limit electromagnetic interference between the motor circuit and nearby control wiring.
