Mitsubishi Electric FREQUPS FW-S10C-1.0K 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 FW-SBT-1.0K.Japan-domestic UPS units like the FW-S10C-1.0K 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-S10C-1.0K Usable on 110–120V mains Yes — set the voltage mode to 110/115/120V. Suitable for the USA, Canada, Mexico, Taiwan, the Philippines (110V areas), parts of Central/South America and Saudi Arabia, and Japan. For 220–240V mains a step-down transformer is required.
