Product Description:

The 175Z7024 is a variable-speed drive manufactured by Danfoss for the VLT 6000 HVAC Drives series. It is engineered for ventilation and air-conditioning systems, where adjusting fan or pump speed can reduce energy consumption and operating noise in building services. The drive interfaces directly with induction motors to match airflow or water flow to real-time demand in air-handling units, chillers, and terminal equipment. Its control functions support applications that require stable pressure, temperature, or flow regulation as operating conditions change.

This model operates from a three-phase input of 380–460 VAC, allowing installation on common commercial power networks without transformers. Its power section provides a mechanical output of 2.2 kW, which is equivalent to 3.0 HP and is suitable for small supply fans, exhaust fans, and pumps. The electronics are housed in a compact IP20 enclosure, which protects against accidental finger contact but requires installation inside a switchboard or comparable protective cabinet. Conducted emissions are suppressed by an integrated Class A1 and Class B filter, helping the installation comply with electromagnetic compatibility limits in industrial and residential areas. The baseline input and output terminals accept analog speed references and provide digital and relay connections for common standalone control arrangements.

The front panel includes an LCP that provides access to parameter menus, local start and stop commands, operating values, and fault codes without requiring external tools. Internally, the drive uses a standard unit configuration that combines the control board and inverter section intended for this power range. Its thermal design supports continuous HVAC blower and pump operation when the required mounting clearances and cabinet ventilation are maintained. The circuit boards have no protective coating, so the unit should be kept away from high humidity, condensation, corrosive gases, and conductive airborne contaminants. Vacant option slots permit later addition of compatible communication or application modules, while the installed analog, digital, and relay interfaces support standalone pressure or temperature loop control.
