Author: Article Manager

Define UPS and its Function

UPS is a device that provides electric power supply to the attached computers or other electronic gadgets during a loss of utility power or when there are outages, sags and surges. Mostly it is used to provide backup power to computers, as for successful operation of the computers it is important to back computer by a UPS. By the sudden loss of utility power computers might end up loosing some important data or damage some component of computers and in order to prevent this, it is vital to protect computers with UPS. Sudden shut down of computers due to power breakup not only can cause data loss but it can also cause damage to the computer component such as processor and motherboard. UPS should not be used as a generator and it should only be used for saving the data and for properly shutting down the computers.

Benefits of UPS

To have the facility of uninterruptible power supply, one need to has an energy storing backup battery, an AC-DC charger and an AC-DC inverter. Today most of the UPS comes with UPS software that works in conjunction with computers to automate data backup and system shutdown procedures in case or power failure when no is there to manually shut down the computer. Another benefits achieved by UPS is that it stops power abnormalities such as power sags, voltage spikes, and surges from reaching the computers and damaging data or other hardware component. It is a fact that 45.3% of data loss occur mostly due to power disturbance.

Types of UPS

Usually there are four types of UPS catering to different power disturbance problems and it is up to the individual choice and requirement that one select a right UPS. The four major types of UPS are:

• Standby or Offline UPS– This type of UPS is mostly found useful for small power spikes and prevent computer from outages. In a standby UPS, a switch is activated and then power is supplied from the battery rather than from the standard line voltage in case of power failure.

• Online UPS- Online UPS is known for providing a much greater level of protection due to its superior power-conditioning capabilities. It offers complete isolation and protection from electrical disturbances by providing conditioned electrical power along with added outage protection. This UPS is the best choice while used for mission-critical applications. There is no delay in backup power in the event of failure of utility power.

• Line Interactive UPS– Line Interactive UPS is online all the time and acts as a battery charger under normal conditions, but switch to battery backup upon power failure.

• Ferroresonant UPS- This UPS uses a ferroresonant transformer as a power buffer for supplying power while the UPS switches to standby power. The energy buffer of the ferroresonant protects equipment which can be affected during the transfer time from the primary to secondary power source.

Northwest Businesses: Power Outages

Once again it is the time of year when Northwest businesses are likely to experience power outages. Power outages can be very costly for small businesses; loss of computers, cash registers, and high-tech equipment are very costly. Loss of  valuable data can be more devastating than losing equipment.

Protect Your Business During a Power Outage

Protecting your Equipment:

High winds cause most of power outages in our area. If there is a high wind warning. TURN OFF and if possible unplug your computers before you leave your business.

Protecting Against a Power Surge:

Most power strips you buy today are also surge protectors, but some are not. Be sure when buying a power strip that it is also a surge protector. This will give your equipment some protection, but it does not protect against low voltage. Low voltage can be has harmful to computers and electrical equipment as a power surge. Check the surge protection on your power strip is working. A surge to a power strip may disable the surge protection.  Look for a power strip that has a “surge protection light” indicating the surge protection is working. If your power strip has weathered a few storms it maybe time to replace it.

Protecting Your Valuable Information:

BACK UP ALL FILES. Use an online file storage service. Be sure to update it frequently. It is also a good idea to keep all data on a hard copy, for example a CD, DVD , or jump drive.

A Word About Generators

Many homes and businesses have purchased generators the past 2 years because of the extensive power outages experienced in this area. Please be aware that most generators produce power what is referred to as “dirty voltage” not at a constant 120 volts. It best not to use a generator to run expensive, voltage sensitive equipment like computers unless you absolutely have to.

Before starting your generator turn off everything in your business. Then after you start your generator begin turning on the essentials. Any appliance that creates heat is going to use more voltage.

Have an electrician wire your generator into your power panel. Do not hook up your generator illegally. If you hook up your generator incorrectly voltage is  back feed  onto  power lines.  This  can injure or kill a lineman working to restore power. When a lineman is  injured or killed from from voltage created by an illegally wired generator, it is easily traced back to that generator.  The person that owns that generator will be liable for injury or death of power company employee and will  prosecuted.

e.releases

This article was copied from the following website in an effort to compare different options for internet press releases:

http://www.ereleases.com/welcome10s.html?gclid=CP7A0Pb8ppsCFSgYagodIz3_Cw

I know. You’re looking to distribute a press release. You don’t want to spend a lot of money. In fact, you’re not quite sure press releases work … or at least work for you.
This is what happens to the average visitor to our site …

* they see we charge a mind-boggling $297* to distribute a press release nationally
* they hit the back-button
* they go to the next site until they get to a free site or a sub-$100 site
* they distribute their press release (they might even try a few free press release sites)
* they get a few clicks to their website but no sales and no media coverage
* they pat themselves on the back that they were right about press releases
* they thank their lucky stars they didn’t spend $297* as they’ve proven press releases don’t work

This is what you don’t know:

* there’s no free lunch (free press release sites exist for ad revenue and to collect your email address for marketing purposes)
* there’s no lunch even there (free and sub-$100 press release sites don’t get your press release to the media OR distribute OVER a newswire)
* distribution OVER a newswire costs money ( PR Newswire charges over $800 for a 500 word press release while Business Wire charges over $750; vs. only $297* for 600 words from eReleases )
* emailing a press release to newsroom@ap.org is not newswire distribution
* most journalists don’t subscribe to RSS feeds
* most journalists judge you by the company you keep (free sites are filled with webpage spam and marketing copy formatted into a press release)
* SEO or search engine optimized press release services generally optimize your press release to rank high on that company’s website, not your website.
