OMRON BU150SW is a 1500VA / 1050W online double-conversion UPS made for the Japanese market. Its output can be set to 110/115/120V, so it also runs on North American and other 110–120V mains. The replacement battery is the BP150XS, and runtime can be extended with the optional BUM150S expansion battery.Japan-domestic UPS units like the BU150SW are often built into Japanese-made machines — semiconductor and SMT lines, inspection systems, machine tools and lab analyzers.
