Product Description:

The FC-102P18KT4E20H2XGCXXXSXXXAXBXCXXXDX is a variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It regulates the speed of induction motors used in fans, pumps, and compressors. Building automation systems can use this speed control to adjust airflow or water flow according to actual demand. Matching motor speed to the required load can also reduce energy consumption in industrial ventilation systems and chilled-water circuits.

The drive provides a continuous mechanical output of 18.5 kW, which corresponds to 25 HP for motors designed for HVAC service. It accepts a line voltage range of 380–480 VAC and operates with three-phase power commonly used in commercial and industrial facilities. A factory-applied coated PCB protects the control electronics from airborne moisture and contaminants that may be present in air-handling rooms. The primary control interface is a graphical local control panel that displays operating data and provides direct access to adjustable parameters. The drive does not contain a brake chopper, so external braking equipment is required when an application produces regenerative energy during rapid deceleration. It also uses a direct connection to the mains supply and does not include the optional C1 configuration.

The drive has standard cable entries under Adaptation A, which provide conventional routing points for power and control wiring. Adaptation B includes no additional mechanical changes to the enclosure. Its IP20 chassis enclosure is intended for installation inside a suitable electrical cabinet that prevents contact with internal components and shields the unit from external debris. A built-in RFI filter reduces conducted electrical interference on the supply side, helping protect nearby control and communication equipment from unwanted noise. The Series Identifier 102 places the unit within the applicable VLT HVAC Drive product group. Its cabinet-mounted design allows surrounding equipment to provide the required physical protection while maintaining suitable space for wiring, ventilation, and service access.
