Best Power
Although the Best Power brand no longer exists, its tradition of reliable and innovative products continues to live on at Eaton. The FERRUPS tower and rackmount UPSs continue to be manufactured in Raleigh, NC, and these “bulletproof” units protect countless critical applications such as 911 centers and military facilities throughout North America. The scalable and redundant Axxium Pro, which has been renamed as the Eaton 9170+, also has a long history of success and is also produced in Raleigh, NC. In addition, our service team has the necessary expertise to service Best Power products still in operation.
