Both the XPRT-6kVA model (4U) and theXPRT-10kVA (6U) are the smallest available solutions including hot-swappable internal batteries, automatic bypass, integrated maintenance bypass, and dual-voltage output.XPRT dual-inverter design provides simultaneous output voltages of 240120V, 208120V, 230115V, 220110V, or 200100V without the need for transformers - saving space, weight, and power. XPRT- 6kVA is available in two configurations:Hardwire model provides terminal blocks for hardwired Input and output connections.Plug and receptacle model provides an L14-30P input cord with output receptacles. The XPRT-10kVA features hardwired input and output terminals. Optional output receptacle module is available. XPRT-10kVA includes one internal power module and two internal battery modules. The chassis contains a bypass switch allowing all modules to be removed without powering down the connected load. Up to threeXPRT-10kVA systems can be paralleled for capacity or n+1 redundancy. 3 Year Warranty on all UPS Electronics Optional service plans to 5 years are available. Modular Battery Packs are available for Extended Battery Runtimes. Dual-Voltage Output: 240120V, 208120V, 230115V, or 200100V. Internal Maintenance Bypass allows UPS electronics and battery to be serviced or replaced without interruption to critical loads.
