CyberPower UPS

[shovenose]

I have a CyberPower UPS from Costco. Works fine, but every time my refrigerator (some cheap shit from Target, doesn't use a lot of power) turns on at least one of my three Samsung monitors turns off and on again. The computer never crashes it has a bigger power supply that is not affected, but it's just annoying.

The refrigerator is not on the UPS, but the entire computer set up including the monitors is. I have looked in the CyberPower PowerPanel Personal Edition that came with it, it does not customize how senstivie the UPS is, which is annoying - APC can do this??

Another thing I might consider is replacing the power supplies of the monitors with something better but I really don't feel like spending the money or time to do that when there is nothing wrong with these, and they are geniune OEM Samsung supplies that came with the monitors!

Any input is appreciated.
Thanks!

PS: I'd rather have CLICK, BEEP, CLICK than the monitors turning on and off. I don't know why!

Re: CyberPower UPS

I am curious if you have just the monitors hook up to the UPS and nothing else, then simulate the lost of power by pulling the cord on the UPS and see if the monitors will still cycle on and off when it switches to batteries mode.

I know for a fact that if I pull the plug on the UPS the monitors have no issues. It's only when the fridge goes on which is not sensitive enough to trigger the UPS which is my problem. I think it has to do with the speed at which the UPS kicks in.

Re: CyberPower UPS

I think when the fridge kicks on, the line voltage drops below the Voltage regulation capture range which will cause the UPS to go into battery mode. What is the model of this Cyber power? It should have transformer tap switching to try to regulate the output voltage, but when it goes beyond the capture range, it will go into battery most, most of them has 2 boosted taps, and one buck tap. If it does beep, then it is on battery mode, tap switching mode will not make the UPS to beep (my does not). May be during the tap switching is what causing the output to drops enough to black out the monitors. If you have VARIAC you can then try varying the voltage feeding the UPS and you can hear the relays clicking when it does the tap switching and then you can see if the monitor will go ON/OFF, that is one way I can think of simulating the cause of the problem.

Taps?

Re: CyberPower UPS

The transformers in the UPS has multi-taps on the transformer which is how it regulated the AC out put to be at 120V (+/-5V is typical) by boosting or bucking. The spec sheet of the UPS will tell you what the capture range is for it to maintain 120V output, when it can no longer regulated when the AC input is beyond the capture range, the it goes into batteries mode. The manual should indicate if it has AVR function or not.

Automatic Voltage Regulation - AVR technology stabilizes the AC voltage and maintains a safe voltage level without switching to battery-mode. This conserves battery life, and delivers cleaner AC power to connected equipment.

AUTOMATIC VOLTAGE REGULATOR
The CP850AVRLCD / CP1000AVRLCD stabilizes inconsistent utility
power. The incoming utility power may be damaging to important data
files, but with Automatic Voltage Regulation, the computer will not
experience damaging voltage levels. An Automatic Voltage Regulator
automatically increases low or decreases high voltage to a consistent,
computer safe 110v/120v. The unit’s powerful sealed lead-acid
batteries will provide power only if the incoming voltage drops below
90v or increases above 140v.

Re: CyberPower UPS

make sure your monitors are not plugged in "surge only" outlet.

whats the exact model of your ups?

Re: CyberPower UPS

Any follow-up on this? Is the problem solved?

Re: CyberPower UPS

Sorry I was awaiting some two prong adapters from Amazon to put the monitors on their own UPS on their own outlet. If this does not resolve it I will post here.


The UPS has AVR but obviously it is just false advertising or else I would not have this problem!!http://www.cyberpowersystems.com/pro...350avrlcd.html

Re: CyberPower UPS

Well, knock on wood, now that i set it up all nice, my monitors no longer have problems even when the refrigerator turns on. YAY Thanks to all who helped.

I have however reached out to cyberpower regarding how to increase tolerance from 90v to 100v as that would make me feel safer about the voltage dips to the connected devices. I hope this is possible, as I know that my old APC UPS can customize this setting, I don't know why a nicer new unit couldn't do that...

Re: CyberPower UPS





Guess I didn't knock on my desk hard enough - still having the problems.

The only thing hooked up the UPS on the battery ports, are my computer and the three monitors.

On the surge only ports, I've got my pair of computer speakers and a hard drive dock. That's it.

I'm definitely not overloading the unit. But it doesn't seem to notice the problems

The monitors only go out half as much as before, but it's still annoying! I kind of understand how you described the transformer taps, however I am not going to take a brand new, under warranty UPS apart to look at it, especially because there's no way I could fix it even if I did.


I bought three of these UPS units, I am having a problem with one of them, where it smells bad and whines while it's plugged in. When it's operating on battery it's fine. Should I bring it back to Costco?

Re: CyberPower UPS

If you get a UPS get a decent one. The cheap ones (like almost all other damn cheap electronics) are prone to blowing up.

Re: CyberPower UPS

So from the screen shot, it looks like it did not detect any Power Outage/Under Voltage/Over Voltage/Boost mode at all, and yet the monitors still black out.
COSTCO has pretty good return policy.

If it blew up at least I could make a big fuss to CyberPower. Right now it's not that it isn't working just it's not sensitive enough!

Problem is if I exchange it for another one, I will have the same problem. And I do not want a refund because then I won't have a UPS!


First world problems.

Refund and GET A BETTER ONE UPS.

Re: CyberPower UPS

They don't have a better one.

Perhaps, but if it took your computer with it? I know a guy on another forum who used a cheap UPS which blew up and he lost that plus $1500 worth of computer.

The real good UPS brands don't do that, and if they do, the company will pay for anything that gets damaged.

We all know how bad cheap PSUs are. A Cheap UPS is not that different.
