DC 5-60V Dual Power Automatic Tranfer Switch,Two Ways Without Power Outage 0.007S High Speed ATS

Worked perfectly on a secondary 12v battery backup to solar system

No where near fast enough switching. There is no what it switches in the claimed .007 seconds. You might as well just buy the cheaper units unless you really need the enclosure

This switch is not 0.007s as advertised, I was hoping it can switch the power on my router without rebooting but so disappointed i should have believe the review.

ok

Does what expected. When auto switching to the back up source, DC power supply, I haven’t noticed any issues and it swaps right over. Going back to the AC power supply it does cause my Starlink router to then reset. Not a big issue as going to DC power source is what takes a little bit for the router and everything to boot up. I haven’t noticed a reboot if going from the primary AC power supply to the DC power supply. I do notice a cycle going back from DC to AC. Like I said not too much of a problem as AC power supply initializes the router much faster than the DC.I have this installed in my rv so when I pull shore power my Starlink will swap over and then run on the DC supply. When I then reconnect to shore power it will kick the AC supply back on. I added som 5.5mmx2.1mm pigtails to get this all connected and no need to strip the ends off my power supply’s.

This is great for diy projects. It is fast switching. This gives you easy access to automate your power plan. I set it up so that when I have solar coming in it uses that but once the sun is gone it switches to grid power. That gives an automated way to use solar every time its available and not have to micromanage it. If you want to have power switching, give this a go. Be sure to read the specs so that you have the right voltage range for your application.

Considering returning this item as I do not have a solid answer from seller on what the two leads are from coming from middle of the device. This device will switch fast from B (backup) to A(priority): B is 12VDC source. A is 12VDC source. When A is off and then turned on, this transfer switch cuts to A(priority) power with an insignificant slight glitch or flicker in the power. When switching from A to B by turning A off, there is a full cutout of power such that the load drops out and back on. If using as backup for a power outage, this will reset and device connected on the load or output.
