Product Description:

The FC-202P2K2T2134H7861 is a variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. It regulates pump and fan motors in water and wastewater systems by adjusting their speed to match process demand while maintaining energy efficiency. The drive accepts three-phase mains power and is designed for centrifugal pumps that require constant pressure or flow control in treatment facilities. Its variable-speed operation allows the connected motor to respond to changing process conditions instead of operating continuously at full speed.

On a three-phase supply, the drive accepts a mains voltage range of 200–240 VAC and draws a continuous input current of 9.5 A. Its apparent power demand is 3.82 kVA at 208 V. The drive delivers a continuous output current of 10.6 A to the motor terminals, supporting a motor output of 3.0 HP or 2.2 kW. Electrical protection is coordinated with a 20 A prefuse, and two digital or pulse outputs provide status signals to a supervisory controller. Conversion efficiency reaches 0.96, resulting in 116 W of heat loss under nominal load. This heat-loss value can be used to determine the ventilation and heat dissipation needed within an enclosure.

The inverter can be installed at elevations up to 1000 m above sea level without current derating and can operate at ambient temperatures up to 50 °C. It tolerates relative humidity levels up to 95% in noncondensing conditions, supporting operation near open tanks or in damp pump rooms. Shielded motor cables may be run up to 150 m, providing flexibility when the drive and motor are installed in separate locations. Output switching frequencies are selectable up to 32 kHz for applications that require reduced audible motor noise. Field wiring accommodates power conductors with cross-sectional areas up to 4 mm², while disconnect links accept conductors up to 6 mm². Using conductors that match the terminal capacities helps limit voltage drop and supports secure connections on long cable runs.
