FEATURES
  • Balance load sharing design for power redundancy with zero transfer time
  • When eight one of the redundant power supplies fails or breaks down, you can easily replace failed unit without any interface to the system.
  • A warning buzzer to indicate any one of the power supplies fails.
  • The warning LEDs are provided
  • Typical Efficiency is 70% at full load
  • 0oC ~ 50oC Operating temperature; 10%~90% RH Humidity
  • Safety meets UL/CSA/TUV
