The UPS connected to the wall, if converting, will keep the second UPS from converting since it will have AC input. The UPS connected to the other UPS, if converting, must not have an AC input and hence the other UPS is not converting. Since you will never have double conversion, there will be no degradation.
If a UPS lasts long enough, the cost of replacement batteries overruns the initial cost. If you are buying quality UPSes, therefore, give more consideration to the running cost of the UPS than to the initial purchase price.⁶. A midrange UPS from the same manufacturer costs about ⅓ that of a true-sine UPS with the same headline specs.
16. As a very rough rule of thumb, the wattage rating of a UPS is approximately 0.6 * its VA rating so, as you have seen, a 700VA UPS is good for a power load of around (0.6 * 700) = 420W (your specs said 405W). Conversely, the minimum VA rating you need is approximately 1.6 * load wattage. Your 700W PSU gives you some idea of how much power ...
A good (online) UPS gives you some protection against over-voltages (how much depends on the type of online UPS), as well as a chance at a clean shutdown. Of course, instead of replacing your PC you may simply have to replace the UPS. Share. Improve this answer. answered Mar 22, 2010 at 18:06.
3. Yes, it will shorten the life expectancy of its batteries. Every night, with the UPS unplugged, the batteries self-discharge. Every day, when you plug the UPS back in, the batteries have to charge back up to compensate for the self-discharge. This daily partial discharge, full charge cycle will reduce the battery life.
The typical (standby and line-interactive) UPS will pass through the line power when in normal mode. Typically only a high-quality UPS will output true sinusoidal AC power when in battery mode. A UPS of lesser quality will convert the DC battery power to a simulated sinusoidal AC wave.
If this is the case, connect the monitor to the surge protected outlet. If you want to keep using the pc, the monitor is crucial, so put that to the battery backup too. Do note, that it will drain the UPS battery quicker because now 2 devices are draining its battery. For that reason, my recommendation would be to use the PC on battery, monitor ...
0. Since your PC restarts when you switch off the mains, the UPS does provide enough power. Otherwise your PC would simply shut down and you wouldn't be able to start it while on UPS. This means the switchover time is most probably the root cause. You'll need a Line-Interactive UPS, which has no switchover at all.
2. I've had a couple UPS in the past, but the beep on this UPS (CyberPower CP1350PFCLCD) is a little obnoxious and loud. The "mute notifications" button only stops it from beeping during a power outage, and their included software doesn't have anything to stop it from beeping when I turn it on / off. I'm fine with a beep to let be know it is on ...
As FiascoLabs notes, UPS batteries use a fibreglass mat to store the acid in the battery. As such, tilting them (or placing them horizontal or vertical) won't effect the battery at all. I don't know if UPS batteries use a liquid acid to store power (like car batteries) but if it does, there should be warnings plastered all over it about tilting ...
