The Select Series UPS Backup Power from Middle Atlantic fits into a 1RU rackspace and has a capacity of 500 volts to power your items. The unit features automatic voltage regulation with a boost only and operates on a 120 VAC/60 Hz current. The outlet bank allows for system reboots and features priority outlets for ensuring maximum run time of critical components and non-critical outlets for load shedding. A 10' power cord is included, and the unit has a surge suppression that utilizes a clean line-to-neutral design to avoid passing noise contamination. A power switch, mute button, and LED status indicators are located on the front of the unit for warning indicators and status notifications. If needed, the battery pack can be replaced via the front panel, and if desired, remote monitoring and power control is available after installing an IP card.
