The most efficient UPS designed for industrial environments. The AIS 3000 offers a new way for plant and facility managers to achieve reliable and cost-effective protection for applications within industrial and manufacturing facilities. Legacy industrial solutions require on-site customization to fit these harsh environments. A modular design with factory installed hot-swappable batteries and electronics reduce configuration time and make the AIS 3000 easy to deploy and maintain. Standard reliability features include NEMA 12/IP51 protection, a standard 2 millimeter thick steel plate enclosure, and user-replaceable air filters. The AIS 3000 ships with dual mains input and a built-in maintenance bypass switch increasing system availability.
