The Powerficient® Eterna™ is a fully customizable Uninterruptible Power Supply that utilizes true online double conversion technology for your critical and non-critical power loads. Our UPS systems are one of the first available on the market to accommodate advanced nickel-zinc (NiZn) battery technology which are housed in the same overall enclosure as the UPS.

Contains rechargeable ZincFive nickle-zinc (NiZn) batteries that offer a more reliable, more powerful, greener, and safer alternative to traditional lead-acid and lithium-ion batteries. The high energy density also creates batteries half the weight of traditional batteries, that are both non-flammable and easily recyclable, with extended cycle and shelf lives, that retain thermal stability while maintaining fast recharge. 

The Powerficient® Eterna™ passes structural integrity & functional operations after a triaxial multi-frequency seismic simulated tests.
