Tripp Lite?s Hot-swap PDU systems enable live-replacement of standard UPS systems for maintenance with no interruption of connected server or networking loads. Dual input power cables support PDU connection to separate Utility and UPS power sources. Manual transfer switch with lighted status indicators controls the source of power to connected equipment between Utility and UPS. Set the switch to UPS during normal operation and connected equipment will receive full-time conditioned power from the UPS. Set the switch to Utility to momentarily power connected equipment from the Utility line cord and bypass the UPS while the UPS system is removed and replaced with a fresh one. Once the new UPS is up and running with all data and electrical connections restored, set the switch back to the UPS setting to once again provide fully-conditioned UPS power to connected equipment. PDUB15 is universally compatible with any Tripp Lite or other brand of 100-127V UPS rated up to 1500VA with a NEMA 5-15P input plug. Pair of attached 5-15P PDU input cables connect to separate Utility and UPS power sources. 8 5-15R outlets support critical networking loads in both Utilty and UPS operating modes. 2U rackmount installation in 2 or 4 post racks with support for space saving rear-post mounting in the same rack space as your Tripp Lite Rackmount UPS (select installations, see manual).
