3ヶ月くらい前からUPSがピーピー鳴り出していたのですが、先週出力電源が無くなり、主電源のスイッチを入り切りしても全く反応しなくなりました。
UPSはSANWA UPS-650Dという機種でマニアルを読むとメーカーに送るか買い直すように書いてありました。
電気屋の私としては、変なマニアルだなと思いながら、底蓋を開けるとバッテリーが2個でてきたので取外し電圧を測ると片方は0v,残りは4vと寿命が来ていました。定格は6v、12AHです。
ネットで探して12V,12AHで寸法もピッタリ同じ物が有ったので、購入し取り付けるとバッチリ復活、2200円で元通り。
The UPS has been making beeping noises for about 3 months, but last week the output power went out and it stopped responding at all even when I turned the main power switch on and off. The UPS is a model called SANWA UPS-650D, and when I read the manual, it said to either send it to the manufacturer or buy a new one. As an electrician, I thought it was a strange manual act, but when I opened the bottom cover, two batteries came out, so I removed them and measured the voltage, and found that one was 0V and the other was 4V, indicating that they were at the end of their lifespan. The rating is 6V, 12AH. I searched on the internet and found a 12V, 12AH one with the exact same dimensions, so I bought it, installed it, and it worked perfectly again.
