Product Description:
The FC-202P3K0T4E20H1 is a variable frequency drive produced by Danfoss for pump and blower control. The unit modulates the output frequency supplied to an asynchronous motor, allowing precise speed control for centrifugal pumps and blowers used in treatment plants and irrigation stations. By matching motor speed to real-time process demand, it reduces energy consumption, mitigates water hammer, and extends mechanical seal life in automated pumping systems. These control capabilities also reduce unnecessary motor operation when fluid demand changes throughout a process cycle.
The drive accepts a mains supply of 380–480 VAC, allowing it to operate with common industrial voltages without an additional transformer. Its input uses three-phase power, which balances line current across the phases and minimizes conductor losses. The inverter provides a continuous motor output of 3.0 kW for the connected machine under the permitted operating conditions. The chassis has IP20 protection, which prevents contact with hazardous internal parts and blocks the entry of solid objects larger than the applicable size limit. Because this enclosure does not protect against water, the drive requires installation in a suitable cabinet when exposed to moisture or airborne contaminants. Proper cabinet ventilation must also allow heat generated by the power electronics to dissipate during continuous operation.
Electromagnetic emissions are suppressed by the integrated RFI Class A1/B (C1) filter, supporting compliance with applicable interference limits when the motor cables are correctly screened. The unit belongs to the VLT AQUA Drive product group and uses control functions intended for variable-torque water applications. The 202 series designation distinguishes this model from general-purpose and HVAC drive lines. When paired with flow or pressure transmitters, the internal PID regulator maintains process setpoints without requiring a separate PLC for basic regulation. Its sleep mode stops the motor during extended periods of low demand to conserve energy. Adjustable ramp profiles help reduce sudden pressure changes during motor acceleration and deceleration, while automatic energy optimization regulates motor excitation according to the applied load.
