Is it okay to leave UPS on all the time?

The UPS is intended to be left on constantly, so there is no advantage to turning it off every day, in my opinion. Additionally, the UPS performs a UPS self test each time you turn it on, and if this happens too frequently, the battery will be slightly unnecessarily discharged. It adds up if you do this a few times per day for a year.

Can a UPS run a TV?

Uninterrupted Power Supplies (UPS) can be used to power a TV, and depending on their size (and price), they can keep the TV running for anywhere between 15 minutes and two hours. It makes sense to use a UPS as affordable insurance for your TV (or other expensive electrical equipment).

What is type of relay?
