Best Power was merged in 1999 with Exide Electronics to form the Powerware Corporation. We still support Best Power products of all sizes and types including Ferrups, Unity, Patriot, and Fortress.
The Best Power Ferrups ups system is currently manufactured as the Eaton Ferrups.
The Best Power Fortress is no longer manufactured, for a comparable replacement Eaton ups we recommend the Eaton 5115 and the Eaton 5PX.
Please call us at 888-330-2538 for information on replacing your Best Power Unity ups system.
