Product Description:
Danfoss manufactures the 176F2985 variable frequency drive for the VLT 6000 HVAC Drives series. Intended for heating, ventilation, and air-conditioning plants that use the Graham application profile, the unit converts fixed-frequency mains power into a variable-frequency output that regulates fan or pump speed in response to building load. By adjusting motor frequency rather than throttling dampers or valves, the drive supports tighter control of airflow and temperature while reducing energy consumption and mechanical wear in building systems.
The drive delivers up to 18.5 kW / 25 HP of shaft power, making it suitable for midsize air handlers and chilled-water pumps. It accepts a three-phase supply of 380–460 VAC, allowing installation on common commercial power systems without a transformer. A front-mounted local control panel (LCP) provides direct access to start, stop, monitoring, and parameter functions, and the panel can be removed for remote mounting when enclosure space is limited. The Compact NEMA 1 enclosure protects internal electronics against accidental contact and falling debris while requiring minimal depth in electrical closets. For supervisory control, a factory-integrated LonWorks free-topology interface exchanges operating commands and feedback over the same twisted-pair network used by other HVAC devices, which can simplify integration with existing building automation wiring.
The inverter is supplied without an RFI filter, so electromagnetic interference attenuation must be provided externally when the installation requires it. Its circuit boards have no conformal coating, making dry, conditioned installation areas important for preventing moisture-related electrical tracking and corrosion. The components use a standard configuration, allowing consistent installation practices across multiple drive panels that use the same model. The drive includes no application options, providing a baseline configuration that can be adjusted for the required Graham control sequence without removing unrelated preset functions.
