Product Description:

The FC-102P22KT4E20H2XGXXXXXXXXAXBXCXXXXX variable frequency drive is produced by Danfoss within the VLT FC 102 HVAC Drives series. It modulates the speed of three-phase induction motors in air-handling units, pumps, and chillers, allowing building automation systems to adjust airflow and water flow in response to demand. The unit converts fixed-frequency line power into a variable-frequency output waveform for accurate motor torque and speed control. This operating method can reduce unnecessary energy consumption when connected equipment does not need to run continuously at full speed.

The drive provides a continuous motor output of 22 kW, allowing it to power compatible HVAC motors without output derating under rated operating conditions. This output corresponds to 30 HP for applications that use horsepower to indicate motor capacity. The input section accepts a line supply of 380–480 VAC, making it suitable for common low-voltage electrical distribution systems in commercial and industrial facilities. The unit operates with three-phase power, distributing the electrical load across three conductors when the incoming supply is properly balanced. Its electronics are installed in an IP20 chassis enclosure, which prevents accidental contact with hazardous internal parts while leaving ventilation openings available for cabinet cooling. The open chassis design requires installation inside a suitable control cabinet that provides the necessary protection from moisture, dust, and physical damage.

A built-in RFI filter reduces conducted electrical noise before it returns to the incoming power supply. Local parameter access is available through the graphical local control panel, which provides a visual interface for entering settings, reviewing operating values, and checking drive status without separate control equipment. Wiring passes through standard cable entries that accommodate conventional power, motor, and control cable routing in cabinet-mounted installations. The power electronics use an uncoated printed circuit board, so the board does not have an additional conformal coating over its components and conductive paths. This board configuration is intended for clean, dry indoor control cabinets where the drive is protected from condensation, corrosive vapor, and conductive contamination. Optional braking, filtering, or line-conditioning components can be selected separately when the motor system or facility power network requires them.
