Product Description:

The 176F0723 is a frequency converter manufactured by Danfoss and supplied within the VLT 6000 HVAC Drives series. It is intended for industrial automation tasks that require accurate speed regulation of ventilation fans, pumps, and compressors in large building control systems. By modulating the output frequency delivered to an induction motor, the drive minimizes energy consumption while maintaining the airflow or liquid flow required by the facility’s HVAC processes.

This model operates from a three-phase input range of 380–460 VAC, allowing direct connection to common low-voltage distribution panels. All power and control electronics are housed in a compact IP54 enclosure that shields the internal boards from airborne dust and water splashes often present in mechanical rooms. Conducted emissions are attenuated by the integrated Class A1 filter, which supports compliance with electromagnetic compatibility limits. Local status information and parameter controls are available through the front-mounted LCP, allowing direct adjustments without external tools. The hardware is supplied in a standard unit configuration, without specialized cooling plates or oversized DC-link components.

The control software includes algorithms optimized for variable-torque motor loads commonly used with ventilation fans and centrifugal pumps. The printed circuit assemblies have no protective coating, so installation in a dry indoor location is recommended to reduce exposure to moisture and airborne contaminants. The application slot has no installed options, so functions such as fire mode or cascade control require compatible external logic when needed. The IP54 housing helps protect the internal electronics while allowing the converter to operate near HVAC equipment in mechanical spaces.
