Product Description:

The FC-202PK75T2136H9354 is a pump-dedicated AC variable frequency drive produced by Danfoss as part of the VLT FC 202 AQUA Drives series. Designed for 0.75 kW pump and fan motors, it modulates output frequency to match flow or pressure commands in water supply, wastewater, and irrigation systems. The drive integrates into industrial automation layouts to reduce energy consumption, minimize hydraulic shock, and extend the mechanical service life of three-phase induction machines.

At full load, the drive delivers a continuous apparent power of 1.66 kVA, drawing 4.1 A from the mains and supplying a continuous output current of 4.6 A to the motor terminals. It accepts three-phase input across a range of 200 to 240 VAC, and its internal IGBT stage operates with an electrical efficiency of 0.95, so only 54 W is dissipated as heat under rated conditions. A built-in semiconductor fuse must be protected upstream by a 10 A prefuse, and the digital control inputs can tolerate up to 28 V DC. The motor side supports 1.0 HP of mechanical power through 4 mm² motor leads, while cabinet terminals can accommodate disconnect cables with conductor sizes up to 6 mm².

For field deployment, the drive remains fully rated at elevations up to 1000 m above sea level without derating and tolerates ambient air temperatures as high as 50 °C when installed in a properly ventilated enclosure. Conformal coating and gasketed slots support reliable operation in environments with up to 95% noncondensing relative humidity, while sinusoidal vibration resistance of 1.0 g supports installation on skids or framed panels exposed to continuous machinery oscillation. The power section maintains stable modulation under these operating conditions, allowing the unit to control small process pumps in installations with limited space, weight capacity, and heat dissipation.
