Product Description:
The 178B2886 is an AC variable frequency drive engineered by Danfoss within the VLT 6000 HVAC Drives series. Designed for building automation, the unit regulates the speed of three-phase induction motors so ventilation fans, pumps, and chillers can respond to real-time load requirements instead of operating at a fixed line frequency. This variable-speed control reduces energy consumption and mechanical stress while maintaining stable airflow or fluid pressure throughout heating, ventilation, and air-conditioning systems. The drive is suitable for use in industrial plants and commercial facilities where motor output must adjust as building demand changes.
The input platform is rated for 525–600 VAC, allowing the drive to connect directly to compatible high-voltage North American power grids without external transformers. Its continuous power capability reaches 15 kW / 20 HP, providing sufficient output for medium-sized air handlers or booster pumps. The Compact NEMA 1 enclosure supports panel mounting in conditioned electrical rooms while providing finger-safe protection against accidental contact with live parts. Users interact with the drive through an LCP (Local Control Panel), which provides parameter access and local start-and-stop controls. The electronics are supplied as a standard unit without expanded input and output modules or redundant cooling equipment.
The drive uses the Graham application category for air-moving equipment, with preset acceleration ramps and PID parameters supporting fan control. The absence of optional application cards means that specialized functions must be provided through separate compatible equipment when required. The drive contains uncoated circuit boards, so it should remain in a clean, low-humidity enclosure to reduce the risk of damage from moisture or conductive residue. The lack of an RFI filter means that electromagnetic interference attenuation is not integrated into the input stage. External line chokes or cabinet filters may therefore be necessary when the connected 600 V supply requires lower conducted emissions.
