Your switch stack, two servers, and the NVR all need clean power, and the last brownout took them down together. You need more headroom than a 1000VA can give you. This unit delivers 1350W of continuous sine-wave output with zero transfer time, so nothing blinks when the grid dips. Same 3U footprint, same eight C13 outlets, same Li-ion pack that recharges in about six hours. Built-in bypass and EPO for service without pulling the loads down. Multi-function LCD keeps you informed at a glance. RCM-marked for Australian installations. Add to cart and stop worrying about the next brownout
