Product Description:
The FC-102P11KT4E21H1XG is an AC variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. The unit converts fixed mains power into a speed-controlled output for induction motors that circulate air or water in building automation systems. By modulating output frequency and voltage, it allows a building management system to adjust fan and pump speed according to actual demand. This control can reduce energy use and mechanical stress in ventilation, heating, and cooling equipment.
The drive accepts a mains input of 380–480 VAC supplied by three-phase power. From this supply, the inverter can deliver a continuous motor output of 11 kW, which is equivalent to 15 HP and provides capacity for medium-sized air-handling units. The unit has no brake chopper, so applications requiring rapid deceleration must use suitable external braking equipment or allow the motor to coast to a stop. Its vector control algorithms support the quadratic torque characteristics commonly associated with centrifugal fans and pumps. The controlled output also helps maintain stable motor operation as airflow or water-flow requirements change throughout the operating cycle.
The enclosure has an IP21 / Type 1 protection rating, making it suitable for clean indoor electrical rooms where vertically falling water droplets may occur. An integrated RFI network meets RFI Class A1/B (C1) limits, supporting electromagnetic compatibility when the drive is installed and wired correctly. Day-to-day operation is performed through the Graphical Local Control Panel, which provides menu navigation, trend readouts, status information, and access to parameter settings. The mechanical kit supports dry-room mounting for B, C, D, and E frames without requiring additional adapters. Adequate ventilation and the required installation clearances should be maintained around the enclosure so that heat can dissipate during continuous operation. The control panel also gives operators direct access to operating values and drive status without requiring a separate display device.
