During power failures, it is still necessary to keep certain functions operating. In these cases, having back-up batteries on hand is imperative. The RE2 rack mount enclosure is specifically designed to accommodate back-up batteries for rack-mounted power supply or chargers. The enclosure features a 2U rack mount chassis for use in standard EIA 19” racks, and it can hold up to four 12VDC/17AH batteries. The RE2 also has quick-release terminal blocks for easy installation and access.
