When UPS is working, the power is automatically cut off every 20 days

This is a backup UPS, and the general backup time is only more than 10 minutes. What you mean, is it in the case that UPS has no mains, if that's the case, it means that the battery is discharged and automatically shut down, which is a normal situation. If this problem occurs in the case of mains, it must be the problem of UPS itself, or find your dealer to deal with it.

I haven't encountered this situation yet, theoretically there shouldn't be this kind of problem, it can be discharged for two hours, it's unlikely, generally it is out of power and then turn on it will definitely not delay for another 20 minutes, it is recommended that you consult the ** business.

It is recommended that you do not let it work at the startup after the first UPS shutdown, if you keep letting it work, the battery may be deeply discharged, resulting in the battery will not flush up.

It's 20 minutes each time.

It can't be a matter of power supply. Or maybe it's just that your UPS voltage is unstable.

Go try it differently. If so, it's a problem with your settings.

I'm also not very good at setting it up. Hehe.

Just to help you analyze the analysis.

Hehe, it seems that the UPS you bought is quite high-end, and it also has a timing function. Haven't seen anything like this.

If your mains power is normal, then there is a problem with your UPS, and you can take it to the dealer to change it!

Is the power outage too long? After some UPS power failure, the battery is discharged, and it will not turn on itself after the call comes again, and it needs to be turned on manually. Otherwise, the UPS is broken.

UPS uninterruptible power supply, power failure and then call, can not work, that is, can not "return", the load can not take power, the "uninterruptible" function is gone.

UPS AC power**, 1 is taken directly from the mains, and the other is from the battery inverter.

Even if the battery is broken, the energy recovery of the mains path should still be checked, and the energy should be provided first, and then the alarm should be called.

Therefore, whether the battery is damaged, or over-discharged, should not cause the UPS not to work after "reset".

Unable to "revert", indicates.

1.There is damage to the mains path (element).

2.Detect damage to the detected line for the restoration of the mains.

Disconnect the UPS power supply, and turn it on when it is fully charged.

Specifically, what brand, what model.

First check the fuse, check the switch, still can't work, find a maintenance master to solve it.

It is a kind of uninterruptible power supply with energy storage device and constant voltage and constant frequency with inverter as the main component.

It is mainly used to provide uninterrupted power to a single computer, computer network system, precision instrument, data center or other power electronic equipment**.

When the mains input is normal, UPS will stabilize the mains voltage to the load for use, this cover is an AC voltage regulator, and it also charges the battery in the machine; When the mains power is interrupted or the power is stopped in an accident, UPS immediately continues the power of the battery in the machine to the load through the method of inverter conversion, so that the load can maintain normal operation and protect the load software and hardware from damage.

UPS equipment usually provides strong protection against either excessive or low voltage.
