Product Description:

The 175Z7361 HVAC drive is produced by Danfoss within the VLT 6000 HVAC Drives series. As a variable-frequency controller, it converts fixed-frequency mains power into an adjustable output that matches the motor load in ventilation and chilled-water circuits used throughout building automation. By providing speed modulation, the drive helps lower energy consumption, reduce mechanical wear, and maintain stable process variables that support occupant comfort and equipment protection. Its variable-speed output also allows fans and pumps to respond to changing demand instead of operating continuously at full speed.

Its input section accepts 200–240 VAC three-phase power and can deliver up to 11 kW (15 HP) of continuous shaft power to connected motors. The drive is supplied in a Compact NEMA 1 housing, allowing panel mounting inside conditioned electrical rooms while still permitting front-panel airflow. Users interact with the unit through an integrated LCP that provides parameter access, diagnostics, and manual run commands without external tools. For installations that are sensitive to electromagnetic emissions, the unit is supplied without an RFI filter, so any required suppression components must be added externally. This arrangement allows the drive to operate midrange fan and pump motors in clean indoor settings where the enclosure remains protected from excessive moisture and airborne contamination.

The configuration is supplied without a fieldbus interface, so speed references are delivered through analog or relay signals rather than serial communication protocols. The control boards have no conformal coating, making the unit suitable for clean mechanical rooms but unsuitable for high-moisture plenums or areas with corrosive airborne contaminants. Internally, the drive uses standard hardware with the baseline platform layout and control architecture. The model includes no application options, while its Graham application profile provides default parameter sets for common HVAC duty cycles. These preset values can reduce the amount of manual adjustment needed when configuring routine ventilation, pumping, or chilled-water functions. External control wiring can provide the necessary operating commands when no serial network connection is available.
