Emergency Power Supply

VX-3000DS

The VX-3000DS is an Emergency Power Supply Manager used for the VX-3000 system. It is a 3U rack-mount unit equipped with a battery charger and dual switching power supplies, which contribute to rack space, energy-saving and lightweight design. The VX-3000DS features easy maintenance as function setting switch and shutdown switch inside the front panel, and fuse replacement can be performed on the unit's rear side.

DC power supply to all system components
Combination of two built-in power source units with a high-performance charger
Automatical switch to auxiliary battery power if the AC power supply is down
VX-3000DS: EN 54-4 certified, Certificate No: 1134-CPR-137
