Product Description:

The FC-202P15KT4E20H1 is an AC variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. Designed for centrifugal pumps and blowers, the drive supplies a motor with a commanded frequency that matches process pressure or flow targets. Adjusting motor speed to actual demand can reduce unnecessary energy consumption in water treatment, wastewater processing, and other fluid-handling systems. The drive can also support stable process control by responding to changing demand without requiring the motor to operate continuously at full speed.

The inverter delivers a mechanical output of 15 kW, which corresponds to 20 HP and supports pumps or blowers within that power range. Incoming utility power can span 380–480 VAC, allowing the same model to operate with several common industrial line voltages without a tap-changing transformer. It is designed for three-phase power, so the rectifier section draws current from all three supply phases. This arrangement distributes the electrical load across the input conductors and is suitable for industrial motor applications. The housing has an IP20 chassis rating, which protects against accidental finger contact with hazardous internal parts. Because the chassis does not provide protection from water or fine airborne contaminants, the drive should be installed inside a suitable electrical cabinet when operating in dusty or damp locations.

Electromagnetic interference is reduced by an integrated RFI Class A1/B (C1) filter that attenuates conducted electrical noise. This filtering supports installation on compatible public low-voltage networks and helps limit interference transmitted through supply wiring to nearby equipment. The unit belongs to the VLT AQUA Drive product group, which is intended for variable-torque applications and includes control functions suited to pump operation. Dedicated pump algorithms can regulate pressure or flow as demand changes, while sleep functions can stop the motor during periods of little or no demand. The internal platform uses the series identifier 202, linking the drive to the parameter structure and compatible accessories used by other FC 202 units. Its combination of variable-speed control, pump-oriented functions, and filtered input circuitry supports use in municipal water systems, industrial pumping stations, ventilation systems, and wastewater treatment equipment.
