Product Description:

The FC-102P1K1T4P55H2XGXXXXSXXXXAXBXCXXXXDX is a variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. Installed between a building-automation controller and an induction motor, it regulates fan and pump speed so airflow or water flow can follow changing demand in commercial and industrial HVAC systems. This variable-speed control helps maintain stable operation while reducing unnecessary full-speed running. In pump applications, the drive can reduce flow by lowering motor speed instead of relying only on throttling devices. In fan applications, it can match ventilation output to occupancy, pressure, or temperature demand.

The drive accepts 380–480 VAC input and operates on three-phase power, matching common facility mains. An enclosure rated IP55 / Type 12 helps protect the electronics from dust and splashing water, while a built-in RFI filter reduces conducted interference to nearby equipment. Local setup and diagnostics are handled through the front-mounted graphical local control panel, which provides direct access to operating data and parameter menus. The unit has no brake chopper, so regenerative energy must be handled externally when fast deceleration is required. These features suit HVAC installations where front access, controlled motor speed, and low electrical interference are important.

Mechanical installation uses the Frame A5, B, and C backplate for open drive back, which allows rear heat dissipation in open-panel layouts. Power and control wiring pass through standard cable entries, helping keep routing straightforward inside the enclosure. The control board uses an uncoated PCB, which is suitable for clean mechanical-room environments where additional conformal protection is not needed. The backplate arrangement leaves room for airflow at the rear of the unit when it is mounted on an open panel. This layout is suited to installations near pumps, air handlers, or circulation equipment in protected indoor spaces.
