Product Description:

The FC-102P2K2T4E20H1XXXXXXSXXXXAGBXCXXXXDX is a variable frequency drive produced by Danfoss within the VLT FC 102 HVAC Drives series. The unit converts fixed-frequency mains power into an adjustable output for controlling centrifugal fans, pumps, and compressors in building climate systems. By changing motor speed in response to real-time demand, the drive can reduce unnecessary energy consumption while maintaining accurate ventilation, pressure, or chilled-water flow. It also supports controlled acceleration and deceleration, which can reduce mechanical stress on connected motors and driven equipment.

The drive accepts a supply of 380–480 VAC and is designed for three-phase power. Its IP20 chassis protects against accidental contact with internal components but requires installation in a suitable ventilated enclosure. Internal filters meet RFI Class A1/B (C1) requirements, helping limit conducted electromagnetic emissions without separate filter modules. Building management networks can communicate with the drive through the programmable LonWorks MCA 108 interface, which exchanges HVAC setpoints, operating commands, and status information. Standard mounting arrangements for A, B, and C frames allow the unit to attach to conventional cabinet backplates. Adequate clearance around the chassis must be maintained so cooling air can circulate through the enclosure and remove heat generated during operation.

The housing uses standard cable entries, allowing common power, motor, and control wiring methods without special entry adapters. The drive has no brake chopper, so rapid deceleration must be managed through an appropriate stopping ramp, motor losses, or other external braking equipment. Its control electronics use uncoated printed circuit boards, making the unit most appropriate for cabinets where condensation, conductive dust, and corrosive contaminants are controlled. The standard language set is available through the control interface for operating commands, parameter adjustments, and status messages. The installed software provides the standard operating functions associated with this model, including motor-speed regulation and HVAC process control. Normal cabinet mounting helps keep the power and control terminals accessible for orderly cable routing and routine inspection.
