Product Description:

The 175Z4881 is a HVAC Drive used for large commercial heating, ventilation, and air conditioning systems. It gives an output power of 90 kW, which is equivalent to 125 hp. This drive has a current rating of 144 A. It enables it to supply heavy loads with stability and reliability.

Its build includes galvanic isolation. It is NEMA 12 rated, with protection from dirt, dust, and dripping non-corrosive liquids, so the unit can be installed in less-than-ideal spots. It is built to function in altitudes up to 3300 feet, with reliable operation without derating between altitudes. It has a sturdy build of 92 kg, meaning its strength and yet still within handleable scope when it comes to being installed in a commercial or industrial setting. Cable installation techniques are versatile, with a maximum of 500 feet for shield types and 1000 feet for unshielded types, meaning flexibility when it comes to arrangements of the system and where components are positioned within a building. The 175Z4881 HVAC Drive is air cooled. It enables efficient thermal management under long operation and reduces maintenance requirements associated with complex cooling schemes. Its design delivers maximum power transfer, motor safeguarding, and adjustability in broad applications across the HVAC industry, from air handlers and pumps to large building fan applications.

Through its combination of high output power, robust protection features, and flexible mounting parameters, this HVAC drive maximizes energy efficiency while delivering stable and controlled operation. The 175Z4881 HVAC Drive is basically a tried and tested solution for powering large HVAC systems. It is engineered to get the perfect harmony of durability, efficiency, and functionality for today's buildings requiring dependable environmental management.
