Vigitron's Vi0017 is designed to handle the demanding requirements for PoE power. With the ability to provide both 802.3af (15.4W) and 802.3at (30W), it reserves up to 10W to respond to limited over-power surges resulting from IP camera accessory functions such as day/night, auto back focus, LED, and PTZ start-up. The extra power will avoid PoE and system shut down, and will save time and money from costly service calls. Built-in overload and over-voltage protection serve to protect both the power supply and device power from damage. The Vi0017 monitors conditions during power outage and will automatically restart power when the condition is no longer present. The Vi0017 operates under a wide temperature range from -30°C to 60°C (-22°F to 140°F).
