The ZENER uZen 303 is a Three phase input-Three phase output UPS ideal for industrial application with regenerative loads. Designed for harsh electrical and environmental conditions this is a long life model.
With todays increased process automation, continuous production lines, power sensitive production equipment and high raw material cost, losses due to interruption of power or equipment failure could lead to high cost of manufacture. The uZen range of UPS systems are typically used in Data Centers, IT & ITES industry and Automated Industrial systems where an unexpected power disruption could cause serious business disruption, Data Loss, Injuries, etc. to protect sophisticated IT equipment, Medical Equipment, Computers, Telecommunication Equipment and other Electrical Equipment.
