DOE Proposes New Energy Efficiency Standard for Uninterruptible Power Supplies

The Energy Department is proposing new energy efficiency standards for uninterruptible power supplies, which are a class of battery chargers, it said (here). The proposed standard would define the product as “a combination of convertors, switches and energy storage devices (such as batteries), constituting a power system for maintaining continuity of load power in case of input power failure.” Comments on the proposed rule are due Oct. 4.
