How could a UPS switch between battery and AC wall socket fast from around 4 ms to 12 ms. What make it especial to switch in that very low time. As far as I know it has relays inside it to perform the switching action, but the relay itself can't switch as fast. I am asking this because I need something to switch between 2 DC lines and I tried multiple 12 V DC relays to 30 amps ones and my devices still has to switch off or to reboot once the main DC power source cutt so the backup can't keep up.
I have a DC power system and AC one. The DC works as the backup batteries and the AC is the city power which I don't care about consumed watts from it, but what I care about is every watt from my batteries as 70% of time I am on batteries.
I have a mini DC gaming rig with 60 watts GTX 1060 and low powered I3 8th gen and my total consumption is around 110 watts per hour. The PC is meant to work on battery systems as his input voltage is from 6 to 36 voltage wide input range and can use 250 watts max components. I already own an AC to DC 12 V adpater 300 watts to power it up, but I don't want it to switch off every time I lose the city power suddenly and I would like to keep it on so I bought a bunch of relays to switch between the AC to DC 12 V adapter and the 12 V battery system but none of them worked properly so I refunded them as the PC has to shutdown or restart at every power switching.
Note that of course I won't use inverter, switch the internal power supply to another AC power supply and use normal UPS to increase my power consumption to double of what I already have..... so please don't suggest AC stuff
I'm sure there must be a good question in here somewhere, but I'm struggling to find it through the 'blog post'. It would appear to be 'how do I keep my UPS working when most of the time it has no mains supply?' to which the answer would be 'get a bigger UPS'… but I'm not sure if that's really it... – Tetsujin – 2020-01-24T19:49:03.230

In my opinion this question would better suite to https://electronics.stackexchange.com
