Product Description:
The FC-202N90KT4131F1081 is an AC variable-frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. It converts the plant’s three-phase mains power into a modulated waveform that allows controllers to regulate pump and fan motors used in water treatment, irrigation, and other fluid-handling systems. The power section is delivered in a compact D3h chassis for cabinet integration, while a larger D5h Type 12 housing is available for installations that require a sealed enclosure.
The inverter accepts a supply of 380–480 VAC from a three-phase power source, matching common industrial distribution networks. Its switching section can operate at up to 32 kHz, which helps reduce audible motor noise at low speeds. The analog reference circuit can drive monitoring equipment with a load of up to 500 Ω, while the digital command terminals tolerate signals of up to 28 V DC without damage. Full output current is available at elevations up to 1,000 m above sea level. Above that elevation, the software applies derating up to the maximum installation height of 3,000 m. Internal terminals accommodate 0.25 mm² control wires, 1 mm² flexible conductors, or 1.5 mm² rigid conductors. The protective-earth stud requires a grounding conductor with a cross-sectional area of at least 10 mm².
The permitted ambient temperature range extends from 0 °C to 50 °C, allowing operation in cool equipment spaces and warm mechanical rooms without derating. When the drive is mounted close to the motor, a shielded feeder with a maximum length of 150 m helps limit conducted electromagnetic emissions. Installations that do not require shielding may use an unshielded motor cable up to 300 m long while remaining within the applicable cable-length limit. The field terminals provide dedicated connections for analog outputs, digital inputs and outputs, and protective earth. This arrangement keeps signal wiring separate from grounding conductors and supports orderly cable routing inside the enclosure.
