UNINTERRUPTIBLE POWER SUPPLY

UPS – UNINTERRUPTIBLE POWER SUPPLY
Uninterruptible power supplies provide protection against mains power faults to computer equipment.
These faults include voltage spikes/interference, over voltage and under voltage, mains supply interruptions and surge protection etc.
These faults can cause computer and electronic equipment that are connected to an unprotected mains supply to malfunction and/or sometimes fail.
A common problem, when burning Cds, DVDs etc. any slight power interruptions to the burning process will halt the recording process and rendered the disc useless.

There two type of Uninterruptible Power Supplies
The lower powered and cheaper type UPS are switch-over types, when the mains supply fails, the UPS switches over to the batteries and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.
NOTE : The mains waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave).
The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and then the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.

I have a Tripp Lite G1010USB uninterruptible power supply that only powers the surge surge-suppressor outlets and not the battery-backup outlets. Unless the UPS is unplugged from the wall, and then i


You know they have a TWO YEAR Warranty ?

Sounds to me that it is faulty (one of the relays or switches is not providing 'through' power to the supposed 'backup' socket when the AC power is on.).

Have you followed the manual ?
available here http://www.tripplite.com/support/model/mid/G1010USB

Have you done a 'self test' ?
'To Run a Self-Test: With your UPS plugged in and turned on, press and hold the MUTE/TEST button for two seconds. Continue holding the button until the alarm beeps several times and the UPS performs a self-test. See "Results of a Self-Test" below.
Note: You can leave connected equipment on during a self-test.' see manual

If the LCD does not give you the answer then it is faulty. Seems like something went faulty on restarting your UPS in the morning.

Seems like plenty of help available from this companys' website.

power supply malfunctioning


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.

after a storm, i had to reset my modem, but although all proper lights light up on router, there is no corded or wireless signal coming through it


Hi dsetzhsd

This is a normal reaction to a power surge or power cut which if severe, can easily damage computer equipment

Turn the (Router/)Modem off with its on/off switch or at the mains, then power it up again. If it has not been damaged, it should reset itself and then sequence itself through the lights. Each light represents the successful restoration of various functions, including Power (shows its powered up), LAN/WAN (shows it has re-established its link with the Network), Wireless (shows it has resumed creating a Wireless Field and broadcasting a Wireless Signal from it), Broadband (shows it has reconnected itself to the Broadband signal coming from your Internet Service Provider[ISP]), Internet (shows that it has reconnected to the internet), plus a light for each occupied channel with an active Device attached to it.

Since storms and power surges and power cuts can damage electrical equipment (especially computer equipment), for the future, (if you haven't already done so) ensure that all your computer equipment has Surge Suppressors/Surge Protectors between each item and the mains electricity. Good quality Surge Suppressor/Surge Protector manufacturers offer insurance type protection against damage if equipment is damaged while connected to their products. See examples here:

http://www.amazon.com/s/ref=nb_sb_ss_i_4_8?url=search-alias%3Daps&field-keywords=surge+suppressor+power+strip&sprefix=surge+su


The ultimate protection, if you live in an area susceptible to storms (and you don't already have one), is an Uninterruptible Power Supply (UPS) between the Surge Suppressor/Surge Protector and the Mains wall socket. This acts like a fast-acting automatic standby generator during a power cut, providing continued power to valuable equipment after the power cut, giving the user 5-30 minutes (depending on price level and model selected) in which to safely shut everything down properly until mains power is restored. See some examples here:

Uninterruptible Power Supply problems. My uninterruptible power supply (UPS) is not backing up during a utility power outage.


First, we do need to full charge it. Then see what's being able to pick up a load of this Ups power or not? If not then it means something is wrong with this Ups. Please put this change.

Hi. I returned from vacation and turned on my power strip and monitor, tried to start my emachine t5026 computer and got nothing. the power light on the back of the power supply is off. If I unplug or switch the power to 220 th elight blinks, faster if I switch to 220 than if I just pull the plug out. I couldn't find any reset switch. Help


Your Power supply is most likely dead.

A power strip is not sufficient protection against black outs, brown outs, power surges and other electrical interruptions that occur in the house. Many PC components are very sensitive to fluctuations in power and power supplies often are among the first casualties when a serious problem occurs.

To protect yourself against these common power issues you should invest in an Uninterruptible Power Supply or UPS. A UPS is basically a battery backup that will provide power when brown-outs or black-outs occur and will protect the delicate electronics in your PC. You can purchase them at most stores that sell computers and components.
