OMRON BU3002RH is a 3000VA / 2700W online double-conversion (always-on inverter) 2U rack/tower UPS made for the Japanese market. It takes single-phase 200–240V input, so it suits most of Europe, Asia, the Middle East and Oceania; input and output are both terminal-block connections for hard-wiring by an electrician. The replacement battery is the BUB3002R, and runtime can be extended with up to three optional BUM3002R expansion battery units.Japan-domestic UPS units like the BU3002RH are often built into Japanese-made machines — semiconductor and SMT lines, inspection systems, machine tools and lab analyzers. Replacing a failed unit with the same model avoids rewiring and re-qualification.
