Product Description:

The FC-202P18KT4E66H2XGC3SXSXXXXAXBXCXXXXDX is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. It is intended for pump and fan applications in which motor-speed regulation improves flow control and reduces energy use in water-handling systems. The converter produces a variable output frequency from the incoming utility supply, allowing induction motors to operate at the rotational speed requested by process controllers. This functionality supports controlled acceleration, stable pressure regulation, and reduced mechanical stress across industrial pumping and ventilation equipment.

The drive provides a continuous motor output of 18.5 kW, which corresponds to 25 HP, and accepts an input voltage range of 380–480 VAC. Its compatibility with three-phase power allows direct connection to conventional industrial distribution systems. The IP66 / NEMA 4X enclosure prevents dust ingress and resists powerful water jets, making the unit suitable for wall mounting in humid pump rooms without an additional enclosure. The housing also provides protection where airborne moisture and corrosive contaminants may be present. Because the drive does not include a brake chopper, energy generated by decelerating loads must be managed through the motor and line impedance instead of an internal braking resistor. This arrangement is appropriate for pumps and fans that generally slow over controlled deceleration periods rather than requiring rapid dynamic braking.

A built-in mains disconnect with a fuse permits electrical isolation during service and protects the rectifier from overcurrent conditions. The electronics have a protective PCB coating that improves resistance to moisture and chlorine commonly found near water-treatment equipment. An integrated RFI filter reduces conducted electromagnetic emissions on the incoming supply lines, helping prevent interference with nearby control equipment. Local operation is handled through the graphical local control panel, which presents operating values, status information, alarms, and adjustable parameters in plain text. The standard language pack supports readable menu navigation, while the smooth imperial cable entry allows properly sized glands to seat without additional adapters. Adaptation B is unoccupied, leaving internal space available if specialized input/output or fieldbus hardware is added later.
