Product Description:

The FC-102P1K1T4E20H1 131F3248 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It converts fixed-frequency mains power into a controlled output so building-service motors can follow changing demand, reducing energy use in fans, pumps, and compressors. The unit fits into building automation systems by accepting standard control signals and regulating motor speed to maintain airflow, pressure, or temperature setpoints with stable closed-loop control. That operating approach helps connected equipment avoid abrupt starts and lets the motor match system load more closely during partial-demand conditions.

Its input section accepts a mains window of 380 - 480 VAC, so the drive can connect directly to common 400 V utility feeds without an autotransformer. The power stage is designed for three-phase power, which supports balanced current draw across the supply conductors and stable torque production on induction motors. The enclosure has IP20 chassis protection, which limits accidental contact with live parts and assumes installation inside a ventilated cabinet. An integrated RFI Class A1/B (C1) filter reduces conducted emissions, and the built-in mains disconnect switch allows local isolation during service.

The mechanical layout supports normal cabinet mounting for A, B, and C frames, allowing the unit to fit common back-plate arrangements used for enclosed installations. Within the product line, the drive is grouped as a VLT HVAC Drive, which indicates functions intended for heating, ventilation, and air-conditioning duty. It carries the internal designation 102, which keeps it aligned with the FC 102 parameter structure used across related models. Built-in application functions such as fan and pump macros support routine speed adjustment for typical HVAC loads.
