Product Description:
The 175Z7028 is an AC variable frequency drive produced by Danfoss for the VLT 6000 HVAC Drives series. Intended for building-services automation, it regulates the speed of fans, pumps, and compressors so airflow or water flow matches real-time load requirements. By adjusting the output frequency delivered to an induction motor, the unit helps reduce energy consumption and mechanical wear while maintaining stable conditions in air-handling units and chiller circuits. Variable-speed operation also reduces the abrupt pressure and airflow changes associated with across-the-line motor starting.
Rated at 7.5 kW (10 hp), the drive can operate a motor with a corresponding output rating without derating. It operates from a three-phase mains supply of 380–460 VAC, while its IGBT bridge produces controlled acceleration and deceleration profiles. The compact IP20 enclosure provides protection against accidental finger contact when the drive is installed inside an electrical panel. Electromagnetic compatibility is supported by a built-in Class A1 and Class B filter that attenuates conducted emissions and can reduce the need for additional filtering equipment in suitable installations. A front-mounted local control panel (LCP) provides access to parameters, fault information, and local start-stop commands. Operators can use the panel to review drive status and adjust operating settings directly from the front of the unit.
The drive is suitable for HVAC applications that require automatic regulation of fan, pump, or compressor speed. Its uncoated circuit boards are intended for dry electrical rooms rather than areas exposed to corrosive vapor, persistent condensation, or conductive contamination. The inverter is supplied as a standard unit with the baseline functions associated with this model. It includes no application or communication option modules, so any required network or control expansion must be selected separately. Compatible expansion modules can support building-automation protocols such as BACnet, LonWorks, or Modbus when the installation requires network connectivity. Internal air paths direct cabinet airflow across the heat sinks, helping transfer heat away from the power semiconductors during continuous operation. Adequate panel ventilation and installation clearance are therefore important for maintaining normal airflow through the drive.
