DC systems are the most reliable as the battery is connected directly to the load without any power electronics that can potentially fail. The SiC based power electronics is heat tolerant enabling operation in +50C.
The Netpower UPS is modular and uses hot swappable modules enabling n+x configurations.
Part load efficiency is the key to a UPS operational economy. The single stage AC/DC conversion using high performance SiC components.
On top of this, the losses in cables are 50% lower.
The Netpower UPS is 100% service from front. The units can be placed against a wall, saving costly floor area. In general a 380 V DC system require 35% less floor area than corresponding AC UPS. UPS with up to 67,5 kW can be fitted with integrated batteries in the same rack creating a extremely compact unit.
