Product Description:

The 175Z7008 AC drive is manufactured by Danfoss for the VLT 6000 HVAC Drives series. It functions as a variable-frequency controller that allows building automation systems to regulate motor speed in supply-air fans, return-air blowers, and chilled-water pumps. By matching motor output to real-time load, the unit supports tighter temperature and airflow control while limiting electrical demand on the distribution network. This speed regulation also reduces unnecessary motor operation during periods of low heating, cooling, or ventilation demand.

The drive connects to three-phase mains rated at 380 to 460 VAC, so it can operate on common industrial power feeders without a step-up transformer. Its mechanical output is limited to 4.0 kW or 5 HP, which is suitable for medium-frame induction motors commonly installed in air-handling units. A slim book-style IP20 enclosure allows dense mounting inside control panels while providing basic protection against accidental contact with internal components. Conducted emissions are attenuated by an integrated Class A1 and Class B filter, reducing the need for additional equipment to meet electromagnetic compatibility requirements. Parameter access and local start-stop commands are available through the front-mounted interface supplied with a local control panel. This interface permits direct adjustment of operating setpoints without requiring access through a remote workstation.

The product is designed for HVAC duty and is supplied as a standard unit with factory-selected components. Its uncoated circuit boards require installation in an environment that is free from corrosive vapors, condensation, and excessive humidity. The standard application configuration includes no integrated fieldbus or I/O expansion options, so any required communication or control expansion must be provided through compatible external modules. Control wiring can be arranged around the available standard terminals for routine fan and pump commands. Common drive diagnostics can be used to investigate airflow, pressure, or temperature deviations in ventilation zones controlled by this model.
