Product Description:

The FC-102P7K5T4E20H1XGXXXXSXXXX is an AC variable-frequency drive produced by Danfoss for the VLT FC 102 HVAC Drives series. Installed inside air-handling or pump cabinets, it modulates motor speed so building automation systems can respond to actual airflow, pressure, or temperature demands instead of running motors at a fixed line frequency. By adjusting the electrical frequency supplied to the motor, the unit reduces energy consumption and mechanical wear in commercial and industrial HVAC systems. It can control equipment such as supply fans, exhaust fans, cooling tower fans, circulation pumps, and other variable-torque loads.

This drive accepts a three-phase supply range of 380–480 VAC, covering common 400 V and 480 V power systems without transformer tap changes. Its input section uses three-phase power, providing balanced loading across the phase conductors. Cabinet installation is supported by standard cable entries that accommodate typical metric gland plates. The enclosure provides IP20 chassis protection, so the drive must be mounted inside a suitable ventilated panel that prevents unintended contact with internal components. Conducted emissions are limited by an integrated RFI Class A1/B (C1) filter, allowing the unit to operate near sensitive control electronics when installed correctly. Users interact with the drive through a graphical local control panel that displays operating speed, current, settings, and fault information. The removable keypad also supports parameter transfer between compatible units. Standard cabinet mounting is available for A, B, or C frame sizes, and the factory mechanical interfaces remain unchanged because Adaptation B is not applied.

For applications that do not require regenerative braking, the power section has no brake chopper. Braking requirements must therefore be handled by the connected load or by suitable external equipment. The control section contains uncoated printed circuit boards, making the drive appropriate for clean, filtered indoor environments where moisture and corrosive contaminants are controlled. A standard language pack provides multilingual text on the display for setup, monitoring, and fault review. The drive does not include a mains disconnect or an integrated harmonic-mitigation option. External isolation, protection, and any required harmonic-control equipment must be selected to suit the connected electrical system and local installation requirements.
