Product Description:

The 175Z7358 is an AC frequency converter built by Danfoss for the VLT 6000 HVAC Drives series. The unit serves as the adjustable-speed interface between a three-phase supply and a fan or pump motor, allowing facility controllers to reduce energy consumption, maintain set points, and minimize acoustic output in commercial ventilation and hydronic systems. By varying output frequency and voltage in response to demand, the converter supports proportional control strategies used in modern building management systems. This variable-speed operation can reduce unnecessary motor output when a connected fan or pump is operating below its maximum capacity.

The electrical input is rated for 200 to 240 VAC, allowing the drive to connect directly to low-voltage three-phase power commonly available in light-industrial and commercial equipment rooms. At the motor terminals, it can continuously deliver up to 4.0 kW/5.0 HP, which is suitable for typical five-horsepower blower and pump applications. The drive uses a compact NEMA 1 enclosure that provides basic protection against accidental contact and supports wall or panel mounting in clean indoor spaces. A local control panel on the front provides access to operating parameters and local start-stop controls without requiring a separate programming device. The internal electronics use the standard unit configuration, with the baseline control boards, input and output terminals, and cooling components for this frame size.

The converter is supplied with no input filter, so any required line filtering must be provided elsewhere in the electrical system. Its printed circuit boards form an uncoated PCB assembly, making the drive best suited for clean, dry electrical rooms that are protected from condensation and corrosive airborne contaminants. The unit carries the Graham application profile, which identifies the HVAC control arrangement selected for this model. It has no fieldbus or auxiliary options installed in the available expansion positions. Standard control terminals remain available for supported analog and digital signals used to connect operating commands, references, and status outputs. The open expansion positions preserve the base electrical arrangement without adding communication or application-specific modules.
