OMRON BU100RW is a 1000VA / 800W 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 BUB100R, and runtime can be extended with the optional BUM100R expansion battery.Japan-domestic UPS units like the BU100RW are often built into Japanese-made machines — semiconductor and SMT lines, inspection systems, machine tools and lab analyzers.
