175Z7363 by Danfoss

The 175Z7363 is an AC variable-speed unit manufactured by Danfoss for the VLT 6000 HVAC Drives series. Intended for building-service automation, the drive modulates fan and pump motors so that airflow or water flow matches the real-time demand signaled by a supervisory controller. By adjusting frequency rather than relying on throttling devices, the product lowers energy consumption, lessens mechanical stress, and supports precise environmental control across heating, ventilation, and air-conditioning zones.

Electrical and mechanical parameters determine where the drive can be installed. Its output capability of 18.5 kW or 25 HP provides enough torque headroom for mid-sized air handlers, while compatibility with 200-240 VAC three-phase supplies avoids the need for step-up transformers in low-voltage plants. The electronics sit inside a compact NEMA 1 housing that permits cabinet mounting in clean indoor areas. Operators use the integral interface, which includes an LCP (Local Control Panel), for local setup and status viewing. The platform is supplied as a standard unit, so no additional hardware extensions are required. Fieldbus communication is left open for future add-on cards.

Configuration tags complete the ordering code. The internal application label is Graham, indicating a predefined parameter set that aligns with that duty profile. Because the build line lists no options, both the application option slot and the fieldbus slot are left vacant, which keeps the hardware arrangement straightforward. The circuit boards have no coating, so installations should avoid high-condensation zones. The power stack is supplied without a filter, which means external EMC mitigation must be handled at the cabinet level. This arrangement suits straightforward HVAC service where a clean power feed, a standard enclosure, and modest customization are acceptable.
