Product Description:

The FC-202P45KT6131G2909 is an AC variable frequency drive built by Danfoss for the VLT FC 202 AQUA Drives series. It modulates motor voltage and frequency to regulate connected pumping, aeration, and filtration equipment. By matching motor speed to process demand, the drive can reduce energy consumption and limit hydraulic shock in industrial water-handling systems. This speed control also supports gradual acceleration and deceleration, which can reduce mechanical stress on pumps, valves, and associated piping.

This model receives three-phase power and is protected by a drive-side fuse rated at 150 A. Inside the inverter, pulse-width modulation operates at frequencies up to 32 kHz, while limited conversion losses provide an efficiency of 0.98 under nominal load. One analog output with 8-bit resolution can source or sink a load of up to 500 Ω. Two digital outputs provide status signals at currents up to 40 mA. The command inputs tolerate control voltages up to 28 V DC, allowing direct connection to typical PLC transistor cards. Process feedback, valve position, or level signals can be returned through a single 8-bit analog channel. The Series Identifier 202 places the unit within the VLT AQUA Drive product group and its common parameter structure.

Operation without current derating is permitted at installation altitudes up to 1000 m. Between that altitude and the upper operating limit of 3000 m, the drive must operate with reduced current. Ambient air may range from the stated minimum of 0 °C to a maximum operating temperature of 50 °C without derating. For motor wiring, the integrated output filter supports shielded cable runs up to 150 m, while unshielded cable runs may extend to 300 m. These cable allowances provide routing flexibility when the pump motor is installed remotely from the control panel, including installations with substantial separation between the drive enclosure and the connected equipment.
