The Vi1120, High Power 120 Watt 56 Volt Power supply is designed to meet the power requirements of CCTV products requiring 802.3at and PoE +++ power. With Level 5 energy efficiently the Vi1120 provides the industry's highest power with the lowest power consumption meeting Level V energy efficiency standards . Over Voltage Protection (OVP) , Short Circuit Protection (SCP) and Over Current Protection (OCP) monitor output conditions and effects rapid shut down to protect power devices with any of these conditions occur. The Vi1120 intelligent system will evaluate fault conditions and once no longer present will return power to normal operations. The Vi1120 is designed to provide power for up to eight devices operating at 802.3af, four devices requiring 802.3at and 2 devices at power levels up to PoE +++. Operating temperatures range from +0 C (32F) to +40C (104F) with the ability to cold start under full load at 25 C (77F ). The Vi 1120 can be used with Vigtron's Vi2701 RX, Receiver and Tx Transmitter to provide extended data and 60 watt transmission for distances of up to 800 feet (242 Meters) and with Vigitron's Vi2804P four port extended distance network switch injector to provide 802.3at power for all four ports with no power sharing.
