The APC Back-UPS BE650G2-GR is a UPS system with surge protection for electronic devices and computers. The adjustable voltage sensitivity adapts the UPS to the respective power supply environment or generator application for optimal performance. The UPS has the following output connections: 2x protective contact CEE 7 (surge protection) and 6x protective contact CEE 7 (mains failure protection). The UPS reserves capacity and bridging time for connected devices that must be switched to UPS battery operation in an emergency (mains failure protection), while less important devices are only protected against surges (surge protection).
