In one of our recent projects, we supplied a new research center of the University of Science Malaysia (or Universiti Sains Malaysia, USM) in Penang with several eGen power backup units. The setup provided hours of backup time for all their computers and office equipment on both floors of their administrative office.

Specifications:
Load: 1000W
Backup time: 4.5 hours
