Mitsubishi Electric FREQUPS FW-F10H-0.5K 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 FW-FBT.Japan-domestic UPS units like the FW-F10H-0.5K 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. We ship genuine new units from Tokyo by FedEx; tell us your country and we will confirm voltage and plug before you order.Quick facts for international buyers Model FW-F10H-0.5K Usable on 110–120V mains No — this is a Japan-domestic model rated for AC100V only. Outside Japan, use it behind a step-down transformer that supplies 100V, or inside Japanese equipment that already provides 100V.
