Product Description:

The FC-202P1K5T4Z55H1 variable frequency drive is produced by Danfoss as part of the VLT FC 202 AQUA Drives series. Designed for cabinet mounting in pumping and aeration applications, the unit converts a fixed electrical supply into variable-frequency output power so the speed of an induction motor can be matched to the required process flow. Its programmable logic and integrated protective features support precise regulation of pumps used in water and wastewater systems. Standard fieldbus options also provide communication paths for linking the drive to a supervisory PLC without relying on mechanical throttling to control flow.

The supply section accepts a mains voltage range of 380–480 VAC. Within this range, the rectifier and DC link feed an inverter that delivers three-phase power to the connected motor. The drive supports a continuous shaft output of 1.5 kW, which corresponds to a mechanical output of 2.0 HP. This power capacity suits pumps that require modest torque while benefiting from dynamic speed regulation. Proper cable selection, overload protection, and panel ventilation should account for the drive’s electrical output and the heat generated by its power conversion stage.

The internal electromagnetic compatibility network is rated as RFI Class A1/B (C1), helping limit conducted emissions when the recommended filters and motor cables are installed. Pump-oriented control functions include sleep mode, dry-run detection, and soft fill, allowing the drive to respond to changing water demand and abnormal operating conditions. Sleep mode can stop the motor during periods of low demand, while dry-run detection helps protect a pump when adequate fluid is unavailable. Soft fill provides controlled system pressurization to reduce abrupt flow changes when operation begins. The numeric identifier 202 indicates the drive line associated with this parameter structure and physical format.
