Product Description:

The FC-102P1K5T4P3RH2XGX is an AC variable-frequency inverter manufactured by Danfoss for the VLT FC 102 HVAC Drives series. The unit modulates induction-motor speed in building-management systems and process plants. It allows ventilation fans, pumps, and compressors to match their output to real-time load requirements rather than operate continuously at full speed. This variable-speed operation can improve energy efficiency and reduce mechanical stress on connected equipment.

The drive connects to electrical service rated at 380–480 VAC, allowing direct installation on common industrial power systems without an external transformer. It uses three-phase power, so current is distributed across three conductors to support balanced operation. The front fascia includes a graphical local control panel that displays parameters and trend curves while providing local start and stop controls for on-site adjustments. An integral RFI filter attenuates high-frequency switching noise before it reaches the supply network, helping reduce conducted electrical interference. The drive is designed with the absence of a brake chopper, so regenerated energy must be managed through gradual deceleration profiles or a compatible external braking module when rapid stops are required.

The electronics use a standard uncoated printed circuit board, which supports direct heat transfer but requires installation in a clean control cabinet. The enclosure should protect the internal components from corrosive gases, moisture, and airborne contaminants that could affect exposed circuit surfaces. The drive’s control functions support airflow algorithms and temperature-sensor options used with heating, ventilation, and air-conditioning equipment. Its configuration structure also allows operating parameters to be organized for fan, pump, and compressor applications without changing the drive’s primary control architecture.
