Suitable UPS for ASUS RT-AC88U

[plato2322]

i would ask Telstra what they do for larger loading of the UPS for commercial customers. You may have to talk the the business contract reps instead of residential. You can place UPSs in series, but you will need to check if the stepped sine wave input to the second UPS will cause an issue. This has been a problem in the past.

Yes, thought this would be an issue but even getting to talk to a techie who knows what they're talking about is a feat in itself, so I was more likely to go with one or the other rather than both and I'm thinking the:

Is what I'll end up getting to do the job. Just have to make sure that when it goes from Power to Battery there is nothing more than a single beep, if that. If it will accomplish that and run a router for 3 hours I'm in front.

Most likely it won't. The UPS you are looking at has low efficiency at under 10% load. You'll lose battery capacity mostly to heat. One more time - you need power backup and not uninterrupted power supply. They are different devices for different purposes. Good luck!

If you go the the specifications tab for that UPS, there is a data entry where you can input the total watts loading and it will give you the predicted runtime for fresh, new, fully charged batteries .

47 min for 100 watt load
22 min for 200 watt load

The output circuitry is designed for at least 40% max load as minimum. Otherwise, it is very inefficient generating AC.
You will need a much larger and/or higher energy density battery and a smaller UPS max load wattage rating to get 4 hrs runtime.. A UPS plus a small generator would be practical.

i understand why you were looking for a DC output UPS. But you would still need to get a DC : DC transformer to output the correct voltage for the router DC input. An then you have the issue of the server power input - AC or DC ? same issues.

A UPS plus a small generator would be practical.

I would suggest wind turbine farm, a dam with cascaded water turbines, Tesla solar panels on the roof and Tesla Powerwall inside for increased efficiency and redundancy. Go green!

you need power backup and not uninterrupted power supply..... I know that, I know they are different devices, I know some do both depending on what power point you use on the device. OK so it's not going to power a router,pc and monitor..... but power drain of just a router will be nowhere near 100w it's closer to 13w so surely it will go for 3-4 hrs, otherwise these things are pretty useless.

 

[Tech9]

otherwise these things are pretty useless

So you know uninterrupted power supplies are not power backup and continue to call them useless for power backup... okay. If you don't accept advice, can't read specifications and rely on luck after trial and error - what's the point of asking questions?

 

[plato2322]

If these Power Backup units can only supply backup power for minutes then they won't accomplish what I need. Seems it would be extremely expensive but I think a router using only 13-20watts of power (not 100watts) could go for 3-4 hrs. Specs are pretty ordinary and only specify the units lasting minutes, so to that extent I don't see their value. No wonder there is a flood of them on the second hand marketplace.

Listen... for an events place, no matter for-profit or non-profit, if you don't provide the needed user experience you'll lose the people coming. If you don't comply to safety requirements for public access places you'll get into legal trouble sooner or later. If you really have known and expected Internet and power interruptions you need alternative ISP to backup your Internet line, UPS devices for critical equipment and emergency power generator for the entire place. The game events can't continue on candles and in an emergency event all fire and safety equipment including emergency lighting, exit door lights, fire alarm system, CO detectors, door access system, makeup air and/or ventilation, etc. have to remain operational. I strongly suggest getting professional help and doing it the way it should be done.

Relax. It's all good and yes all safety requirements are in hand, well and truly. We mostly play during the day, so interruption to lights, air con., fans and even the hws in the kitchen won't be a concern. No we don't have regular or intermittent power issues or internet issues. The internet issue can be solved with a router that has a 4G backup in the event of internet line outage and I'm sure one of these backup units 1600VA units will run a router for 3-4 hrs. However, most these units DON'T tell you how long they will operate under any loads. A Bridge event goes for no longer than 4 hours. The active power drawer for one of these modems is 13 watts so I'm hopeful something can run this for 3-4 hours. If not we're just out of luck. Life goes on. thanks

 

[Tech9]

Relax.

Have a nice day.

To calculate the backup time for my 12W router using a 1200 VA (720 W) UPS, I can use the following formula:

Backup Time (hours)=UPS Capacity (Wh)Load (W) /Load (W)

1. Convert UPS VA to Wh: Since the UPS is rated at 1200 VA, and assuming a power factor of 0.6 (typical for UPS systems), the effective wattage would be:
   UPS Capacity (W)=1200VA×0.6=720W

Since the UPS can deliver 720 W for 1 hour, I can convert this to watt-hours (Wh):

UPS Capacity (Wh)=720W×1hr=720Wh

1. Calculate Backup Time:
   Backup Time=720Wh /12W= 60hours

So, with a 12W load from my router, I should be able to expect approximately 60 hours of backup time from a 1200 VA UPS, assuming the UPS is fully charged and operating efficiently.

Of course conditions (like UPS efficiency, battery age, temperature, etc.) may reduce this time, so it's good to have some margin in my calculations, after all I'm only looking for max 4 hours runtime..

I’m on 120v/60hz and use an APC BR1500MS2. I get about 3.75 hours of backup power for my cable modem and RT-AX86U Pro, and has worked flawlessly during power outages with no downtime on the equipment when switching.

One feature to look for is the ability to mute (I learned the hard way with a prior UPS.) Many UPS devices have an alarm that will continuously beep when the utility power is pulled. You may not initially think that it matters much, but it will drive you bonkers to the point you’d rather live without internet than keep hearing that beeping! Check the specs and read reviews to ensure what you buy has the capability of being silenced.

Doesn't that model (most models/brands have a mute button on the unit to silence the beeping? I use 1500Va models too. BX1500M to be exact and one of the 3 buttons is a mute. I've not heard a beep in a long time. Great for when you're sleeping and the power goes out

Yes, this adds up to me. Sadly, muting the beeps should be as simple as a physical button but seems need to check to see if it can be done by software application... why one should repeat when on battery power is beyond any purpose other than annoying. Like isn't that why people buy these things?

It is as simple as pressing a button. See the manual: https://download.schneider-electric...-6291B-EN.pdf&p_Doc_Ref=SPD_BU-UM-990-6291_EN. In addition to the software override already mentioned;

Quick Mute
The Back-UPS is able to temporarily mute user correctable audible alarms such as On Battery. During such audible alarms, a short press of the POWER button will temporarily mute the audible alarm until the condition has been reset. A short double beep will confirm that Quick Mute has been activated. Pressing the POWER button for more than 2 seconds will turn off the UPS.
Other critical events such as Battery replacement and Charger notification can not be temporarily muted. The unit in these cases must be turned off.

Thanks, the reality is I don't even want the thing to start. I don't want an audible alarm at all. This will be mounted on a top shelf which means it will be a total 'pain in the a**' to have to get on a small ladder to press a button. Don't want any alarm full stop. thanks.

So that's where the software configuration option comes in. Should be a one-time task as far as I can tell. But like I said, check with customer services to be absolutely sure that's the case with your particular model.
