Product Description:
The VLT6005HT4B20STR3DLF00A00C0 is an AC variable-frequency drive manufactured by Danfoss for the VLT 6000 HVAC Drives series. It converts fixed-frequency power into a regulated output that allows air-handling units, chillers, and circulation pumps to match real-time demand from a building automation system. By varying motor speed instead of relying on mechanical throttling devices, the drive improves energy efficiency and reduces wear in industrial automation and commercial climate-control installations. Its variable-speed operation also helps maintain stable airflow, water pressure, or temperature as system demand changes throughout the day.
The drive has a continuous output rating of 3.0 kW (4.0 HP), making it suitable for small and midsize induction motors used in fan and pump equipment. It accepts three-phase input from 380–460 VAC mains, allowing direct connection to compatible supply panels without a step-down transformer. A narrow book-style IP20 enclosure supports compact cabinet layouts while preventing accidental contact with live electrical parts. Conducted emissions are reduced by an integrated Class A1 and Class B filter, helping the installed system meet applicable electromagnetic compatibility requirements. Local operation, parameter setup, and fault diagnostics are handled through an included LCP (Local Control Panel). The detachable panel provides direct access to operating values and drive settings without requiring a separate programming device.
The controller is configured for HVAC duty, so its default control functions accommodate the variable-torque behavior of ventilation fans and chilled-water pumps. It is supplied as a standard unit without additional equipment such as an integrated brake chopper. The drive uses uncoated circuit boards, making it appropriate for clean electrical rooms with minimal exposure to corrosive chemicals or persistent airborne moisture. The application option slot is unpopulated, and no fieldbus option is installed in the base configuration. These open interfaces can accept compatible communication or application cards when additional control functions are required. Installation inside a suitable electrical cabinet protects the IP20 enclosure while maintaining the clearances needed for ventilation and cable routing.
