OMRON BZ50LT2 is a 500VA / 300W standby (offline) UPS made for the Japanese market. It is rated for AC100V only, so outside Japan it needs a step-down transformer or a 100V supply. The replacement battery is the BP50LT2.Japan-domestic UPS units like the BZ50LT2 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.
