Product Description:

The 175Z7027 AC drive is produced by Danfoss for the VLT 6000 HVAC Drives series. As an HVAC frequency converter, it regulates induction motor speed in ventilation, air-conditioning, and pumping systems connected to larger building automation networks. By supplying a variable output frequency instead of operating motors directly across the line, the drive can improve temperature stability, reduce fan noise, and limit mechanical stress in air-handling units and hydronic systems. Its control capabilities make it suitable for industrial facilities that need adjustable airflow or fluid circulation without continuously operating motors at full speed.

The input section accepts a line voltage of 380–460 VAC, covering common 400 V industrial power supplies. Within this voltage range, the drive provides a continuous mechanical output of 5.5 kW, equivalent to 7.5 HP, providing sufficient capacity for medium-sized supply fans or secondary pumps. The enclosure has a Compact IP20 rating, which protects against finger contact with live components when the unit is properly mounted inside a cabinet. Conducted electrical emissions are reduced by an integrated Class A1 and Class B filter, helping the installation meet typical electromagnetic compatibility requirements without separate external filters. Local operation is available through a detachable LCP (Local Control Panel), which provides access to parameter settings, fault resets, operating information, and manual speed references from the front of the drive.

The factory configuration is supplied as a standard unit without additional hardware modules preinstalled. Its circuit boards have no protective coating, making the drive more appropriate for clean, dry electrical rooms than for high-moisture or washdown areas. The application option slot and fieldbus position are unpopulated, so onboard BACnet, LonWorks, sensor interfaces, and extended input or output functions are not included in the factory configuration. Compatible networking equipment or expansion modules must be installed separately when the application requires communication with additional building controls or field devices. The basic arrangement supports direct motor-speed regulation through the drive’s standard controls while leaving the designated expansion locations available for later system integration.
