Your server's been riding the internal battery for twenty minutes and the runtime counter is ticking down. You need hours, not minutes. This pack bolts onto your existing SRT 3kVA RM and extends runtime through a prolonged outage. Lead-acid cells at 96V. Cell, module, and cabinet-level monitoring so you see actual remaining runtime, not a guess. 2U rack mount. Slots into SRTRK3 or SRTRK4 rails. Operates from 0 to 40 °C, handles 95% RH non-condensing. Add to cart and have it racked before the next storm season hits
