Uninterruptible Power Supply.
WARNING: Do not open your UPS if you don’t understand what you’re doing. Always remove the mains plug & switch off the device. Do not touch the internal components – you may get an electric shock.
DO NOT SHORT-CIRCUIT THE BATTERY!
Mercury 600VA UPS
Used to power my PC & 17” CRT monitor.
The power electronics circuit with all its relays, inverters & transistors.
The transformer.
Changing the UPS battery is very easy. Open UPS, remove the old battery, buy a new battery with same specs, & connect red jumper to red pin & black jumper to black pin. That’s it!
So if you have a UPS with a dead battery, there is no need to buy a new UPS. Just change the battery & it’ll be as good as new.
