Product Description:

The 175Z7035 is a variable frequency drive manufactured by Danfoss within the VLT 6000 HVAC Drives series. It is supplied for heating, ventilation, and air-conditioning plants where precise motor speed control improves airflow regulation and reduces energy consumption. The device converts fixed-frequency three-phase mains power into a modulated output that matches the real-time load on fans, pumps, and compressors. It connects to building distribution panels and is typically installed inside equipment rooms close to the mechanical plant.

This drive is optimized for HVAC duty cycles and accepts a line input of 380–460 VAC, so it can be wired directly to common 60 Hz utility feeders. Its continuous output capability reaches 45 kW / 60 HP, enabling speed regulation of medium-sized supply or return fans without external step-up transformers. The electronics sit inside a compact IP20 housing that guards against accidental contact but relies on the surrounding panel for forced-air cooling. Operators program parameters through the front-mounted LCP, which combines a keypad with a segmented display for quick setup and fault reading. Conducted emissions are reduced by the integrated Class A1 and B filter, helping the installation meet commercial electromagnetic compatibility limits without additional line chokes.

The 175Z7035 is supplied in a standard configuration without dedicated application modules. Its control boards have no conformal coating, so the unit should be mounted in a dry, filtered enclosure to avoid moisture-induced corrosion. The drive has no fieldbus interfaces, so speed references are provided through analog terminals or the built-in control panel. These input methods allow the drive to receive conventional control signals from building automation equipment without requiring a communication add-on.
