1. Product Overview

      YDC-SDJJ series adopts mature dual DSP full digital online double conversion topology with three-phase input and single-phase output design, specially optimized for small-capacity scattered power consumption scenes. The whole machine is made into ultra-thin 2U rack structure, which can be directly embedded into standard server cabinet, with light weight and neat layout.

      This UPS can be matched with 16~20 pieces of lead-acid batteries, and different battery groups correspond to adjustable output power factors of 0.8/0.9/1.0, which can flexibly adapt different load types. The equipment is equipped with complete self-diagnosis and multi-layer safety protection functions, supporting DC cold start without mains power. Standard RS232, USB and EPO emergency power-off interfaces are reserved, and SNMP network management card can be selected to realize remote unattended monitoring through industrial Internet platform.

      The product has wide voltage and frequency adaptation capacity, which can effectively filter various grid interference such as surge, voltage flicker and peak pulse, and output stable pure sine wave power for precision terminal equipment. It is widely applied in financial outlets, institutional branches, campus weak current systems and other small power occasions.
