About the Middle Atlantic Select

View user manual
Select Series UPS Battery Backup Systems are a competitively priced option for ensuring uptime of equipment in the event of a power outage or power anomaly. Select UPS backups are designed for both AV and Security applications. Plug it in, feel confident, and simply focus on creating an amazing AV experience. The control you need to remotely monitor the uptime of your equipment. If remote monitoring and control of the UPS is necessary for your AV system, you can achieve that with an optional IP card. Quality protection without the price tag. Select UPS backups use a simulated sine wave, keeping the cost down while keeping your equipment protected and powered. Make the switch (almost instantly.) In just 8ms of a power outage or anomaly, the UPS will transfer equipment to battery power. Prevent the silent death of your equipment. Over and under voltage slowly degrade your equipment and shorten its lifespan. With automatic voltage regulation (AVR), the UPS will switch to battery and power your equipment till the voltage returns to a normal level. Choose which equipment to prioritize. With separate critical and non-critical outlet banks, should an extended power outage occur, the UPS will cease powering the non-critical equipment via load shedding. Protect your equipment. Each UPS backup comes with basic surge protection and EMI filtering. Stay in the know. An LED status indicator on the front of the UPS assures you your equipment is still being powered, and alerts you of low battery level, or of battery overload. Replace the battery pack with ease. The hot-swappable battery pack can be easily replaced via the front panel for easy service without disrupting the system.
