OMRON BY75SW is a 750VA / 450W standby (offline), sine-wave output 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 BXB75S.Japan-domestic UPS units like the BY75SW 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.
