Good and hope you get a solution.But sensitive electronics do fail some times irrespective of the power supply conditions but your case since it was happening frequently to multiple devices we can have some assurance with the ups. BTW it was me who advised Lingam as well and hope it’s a good solution for you both so you both don’t end up killing me if something goes wrong
The UPS part here is clearly for power back up but we are losing on the pure sine-wave output part according to subbu sir. Is it better if we go for a CVT/Isolation transformer alone without UPS?Good and hope you get a solution.But sensitive electronics do fail some times irrespective of the power supply conditions but your case since it was happening frequently to multiple devices we can have some assurance with the ups.

Yeah it is upto each individual. My case I have decided to take the risk of using only an isolation transformer. I have no surge protection or voltage stabilizer. I have also connected my Tv directly to the mains with no protection and sadly it’s the most expensive gear in my chain. With the Tv in chain my PA screams like a motor.Not sure why but even after LG replaced the panel, power supply board and power chord the tv is causing the PA to scream like a motor.The noise is passed through the power chord of the tv. Thankfully isolation transformer is able to block it. Also at times the same behaviour mildly without the Tv so some other devices are also is causing it. With isolation transformer all other devices are electrically disconnected and hence the PA doesn’t make any sound.
I use an Emerson 3 kva double conversion online UPS on a dedicated phase to connect my audio setup. It outputs a steady 230V as per the display. Despite this, I've had an issue of equipment damage due to power surge, which the online UPS should have prevented. I'm now considering adding an over/under voltage cut off device between the online UPS and the power strip. I can set the range to, say, 210 to 250. My question is whether this device will cut off the power quickly enough in case of a surge? And will this arrangement be sufficient protection for my equipment?All you need is an overvoltage/undervoltage cutoff device. And one that let's you set those cutoff thresholds. Like this one: https://www.amicikart.com/products/c5c77f7440/450878000000062247
Unless you want to spend big bucks for audiophile protectors - in which case...
Found some explanation here, could be complete marketing but this comes from the manufacturers
You think this kind of Product would be of any use to cover more power related threats?
This doesn't appear to have user selectable cut off voltages. Otherwise it looks good.
According to the company the time to cutoff is user settable - lowest setting is 0.1 seconds.
Is that good enough?

I recall the Denon AVR I got in 2005 explicitly mentioned it should NOT be connected to any UPS. So is it is okay do it with online UPSs?
I have a Rega Brio, Schitt Dac, and a RPi streamer I want to protect.
Should I go for a UPS or will a product like this suffice?

The protector will become permananently shorted and due to this equipment will get zero voltage and get protecte3d. Also your house fuse/circuit breaker will go off whenever the surge protector will be connected. Basically once the surge protector has experienced overvoltage it will become useless unless you replace the MOV inside. (There are some MOVs that open instead of shorting. But when one uses these kind of MOV, they will have a warning LED to indicate fault). The surge protector above has a resettable fuse. If this fuse goes off, make sure your voltage is ok, before connecting the equipment and resetting the fuse.

Thanks for the detailed description
Consider using power conditioner like surgex it's the best inhave been using the same over 2yrs now
Against a surge of what origin? For power surges from the grid, possibly good enough. For a direct lightning flash, nothing will protect except physically unplugging the equipment. For a side flash, maybe. But there's no absolute guarantee and I wouldn't bet on it - there are too many variables.
Thanks @keith_correa . This is useful. So a double conversion UPS or a CVT plus such a device should provide a safeguard in most situations, except in the event of a direct lightning flash. In addition, will an isolation transformer provide added safety?
