Product Description:

The FC202P18KT4E66H2XGC3SXSXXXXAXB is an AC variable frequency drive developed by Danfoss within the VLT FC 202 AQUA Drives series. Designed for pump and fan regulation in water treatment and distribution, the unit converts a fixed-frequency three-phase supply into a variable output that matches process demand. By controlling motor speed, it reduces energy use and mechanical stress during continuous industrial duty. Within a supervisory control system, it acts as the speed-regulating element that helps maintain constant pressure or flow while reducing surge events. The inverter also adjusts output frequency and voltage so connected motors can start and run more smoothly than with direct line operation.

The drive uses a three-phase 480 V input and reaches a maximum input current of 31 A, while delivering a continuous output current of 34 A to the motor terminals. With an operating efficiency of 0.98, it releases only 465 W of heat at full load, which helps the B1 enclosure remain within temperature limits. The housing has an IP66 / NEMA 4X rating, protecting the graphical LCP, coated control board, and internal sensors from washdown and dust. Standard cable entries simplify wiring, and the line side includes a disconnect and fuses. The drive does not include a dedicated brake chopper because pump deceleration is handled through controlled ramping.

For upstream protection, the drive accepts a maximum pre-fuse of 63 A and is assigned to Category 3 immunity for conducted and radiated disturbances under industrial installation rules. Under normal overload duty, it supports 25 hp or 18.5 kW output for pump and fan service. Emission limits follow Class A2, and this rating suits enclosed utility spaces where electrical noise control remains important. The overload capacity is intended for applications that need steady torque during flow regulation rather than abrupt stopping cycles.
