We get frequent power surges in this building and bought this to keep the computer on, but when the power surges the UPS says power overload and beeps until it is restarted.

UPS in overload. Try removing some of the attached devices one at a time to determine which on is causing the overload... it may also be a combination of devices causing the overload.

Hi Subramanian,
If this is a small desktop UPS like the one pictured in your post then it is most likely overloaded. If you have a printer plugged into the UPS then try unplugging it from the battery backup outlet(s) and into the surge protection outlet(s). Other things to try would be to unplug connected devices until beeping stops... and a good away to narrow it down is by unplugging one device at a time to find the one causing the fault. If one device is the cause then plug that device into a surge outlet, another UPS, or into the building outlet -- if not then plug it back in and try another device until you find the one that is overloading the UPS. **There may be more than one device that is plugged into your UPS that is overloading it**
Hope this helps. If you would like more assistance please give me a call: 407.380.9200.

Most surge protection power boards will protect computer equipment from mains spikes and surges.
A better and more expensive solution is to use an uninterruptible power supply (UPS). These units provide surge and spike protection and also provide power in the event of mains power failure.
Make sure you select an UPS model that meet the power requirements of all your computer equipment that is connected to the UPS with a mains down time of say 1/2 hour to give you time to shut down your computer in an orderly manner.

Try unplugging some equipment from the UPS. The total load should be less than 865 W. Printers and scanners often are culprits.Some gaming desktop computers can have a power supply that will be too much for this UPS. (I've found that even having the printer on the surge only part of the UPS can be a problem. I have the printer on a separate surge protector.)

Since the overload is new, did you add any equipment to the UPS recently or upgrade components?

If you reduce the load, and the problem continues, the UPS may have a fault in the circuitry. If it is under warranty, contact APC.

I hope this helps.

(I have replaced APC units after 3+ years when they can't properly recharge the battery - with a new battery. The symptoms are 1) getting a overload when a small load is on the UPS. Small load - desk lamp, 13" TV or 2) not keeping the item on when the power goes off.)

There should be no problem with what you are trying to do, one way or another. Just be sure not to overload your UPS (battery protected outlets). I myself have a power bar connected to my UPS to increase the number of battery protected outlets and everything works fine.

this is normal when especially when we have short flow of power,or power spikes,surges and sags.it is not overloaded at all i had such a problem some times back en ma technician told me it is ok

First, most of the UPS sensitivity can be adjusted. Setting a higher sensitivity will make the UPS compensable much faster if the current goes to high to too low thus always providing a good power quality to the equipments. For example, on a BackUPS RS the low level can be configured from 94V to 104V and the high level from 126V to 136V. An entry-level UPS such as the APC BackUPS ES will switch to battery mode as soon as the power goes out of the sensitivity range. On the other hand, a high-end UPS for workstation like the APC BackUPS RS has a feature called Automatic Voltage Regulation (AVR) that compensate at some extent without requiring the battery; this makes the battery last longer before needing to be replaced.

Second, most of the UPS have "Battery Protected" and "Surge only" outlets. Make sure that the computers are connected to the "Battery Protected". The "Surge only" outlets will only protect from parasites or surges like a thunder storm. They should be used for less important stuff like a desk lamp or devices with high demand peek such as a laser printer.

Third, the use of a power bar connected to the "Battery Protected" side should not have any impact as long as it is not overloading the UPS. Personnaly, I have a power bar connected to both my UPS.

I agree with first thought circuit overload.

I dont think it is the printer, I think it is your power supply in house. Just moving it to another socket does not change it from what might already be a circuit with a lot of load already.

You are experenceing surges that are normal operation ie at power on quatz lamp turns on reaching temp of 180 deg cel, then idles, if print command is issued back on comes the lamp drawing power.

Hello,

My name is Vikram Kumar Thumu, from India-Hyderabad. I have seen your message on the issue related to Shutdown of UPS whenever there is a Power Surge. I would like to provide my suggestions on the issue. I hope that this should work for you and will resolve the issue.


I see that you are using


Generally, the issue happens if you are not using the UPS as per Manufacturer specifications or if it is overloaded frequently then UPS  shutdowns


To isolate the issue, I recommend you to check and go through below information.

If you see ON BATTERY a Yellow LED OR Flashing Yellow
LED with Audible Alarm (Beeping) then it means this condition for the On-Battery LED can indicate 1of 2 problems: They are:

1. The UPS is on battery backup and an intermittent audible alarm is on. The UPS will begin shutdown procedure.

2. Battery is low. The UPS will sta rt shut down. The buzzer sounds an audible alarm .


if you see a Solid Red on your UPS , then it means that UPS is either fault or overload.  It happens if there is a issue with UPS. The LED will be lit continuously and the unit will sound an audiable alarm for 10 seconds. Other cause could be with Battery is weak or Bad, the Battery needs to be replaced under this condition.

If you use a Flashing Red LED, then it means that battery is trying to give more power than it should. It happens then UPS is overloaded.

Let me tell you,,,,

Only data sensitive equipment such as a computer, monitor and external drive should be plugged into these outlets. Battery power is automatically

provided in case of a power outage. Power (AC or battery) is not supplied to these outlets when the UPS is switched off. (Do not plug surge protectors or power strips into the battery back up outlets).

 Most Important factor that effects the issue is that,
 

Caution: Never connect a laser printer or scanner to the backup outlets of UPS with other computer equipment. A laser printer or scanner draws significantly more power when in use than when idle. This may overload the UPS.

And caused the UPS to shutdown whenever there is Power Surge

To isolate the issue further, let me tell you the way where you can test the UPS if it is fine or not.

1. Charge the UPS for around 4 hours, and try below steps.

  

To Conduct a Self Test

 

Use the self-test to verify both the operation of the UPS and the condition of the battery. In normal utility power, push the On/Off/Test

button less than 2 seconds and the UPS performs a self-test function. During the self-test, the UPS operates in back-up mode.

Note! During the self-test, the UPS briefly operates on- battery backup power (the on-battery LED comes on). If the UPS passes

the self -test, it returns to on-line operation. If the UPS fails the self-test, it immediately returns to on-line operation and lights the replace battery LED. The loads are not affected. Recharge the battery overnight and perform the self- test again. If the replace battery LED is still on, the battery will need to replaced.

 

This should resolve the issue for you.

 

 If you need any further assistance on the issue, you can mail me at [email protected] . I'll be glad to help you.

 

Bye.
