1. Product Overview

      Different from floor-standing tower UPS products like EP-KL and YDC series, EP-JJ is specially optimized for standard server cabinet installation, adopting advanced DCS digital online double conversion control technology. It supports flexible input and output wiring modes, has complete intelligent monitoring and network management functions, can adapt to complex grid fluctuation effectively, features high input power factor, low current harmonic distortion and wide voltage tolerance.

      The embedded touch color screen integrates real-time data display, fault alarm and parameter setting, no extra local control terminal is required. The whole series supports multi-unit parallel connection with shared battery group, convenient for capacity expansion of growing IT loads. Rich communication expansion options meet centralized O&M demands of distributed branch computer rooms for telecom, finance and public institutions. Compact rack size saves cabinet space, neat layout for standardized machine room construction.
