Surge Protectors
You may not be aware of it but power surges happen all the time in homes and businesses. Everyday activities such as starting the dryer or dishwasher, using the garbage disposal, operating the copier, turning on the air conditioner or opening the garage door cause power surges. These small, frequent bursts of electricity can slowly deteriorate the internal circuitry of any device that is plugged in to a power outlet, phone line or cable.
Spikes of electricity, from lightning for example, are rapid and infrequent but much more powerful and destructive to computers, TVs, and other electronic devices.
Surge protectors are designed to prevent damage due to electrical surges and spikes. They act like a sponge, absorbing excess voltage before it reaches devices that are plugged into them. This protection is exceedingly important for valuable electronics and devices that store important data. Devices with microprocessors or “chips”, which are used commonly in most electronic devices, are particularly sensitive to voltage fluctuations. Portect yourself from costly Tv Repair !!
Consider using a surge protector on these electronic devices:
o Computers, laptops and portable hard drives
o Printers, copiers and scanners
o Phones and fax machines
o Scanners
o TVs and surround sound systems
o VCRs, DVRs and DVD players
o Game systems and stereos
o Microwaves, convection ovens and other kitchen appliances
o Medical equipment
o Tools and machinery
o Anything that’s recharging
When shopping for surge protectors, compare them for these features:
o UL clamping voltage - The lower the UL clamping voltage, the better protection. Make sure the rating reflects 500 amp test results for household or office use.
o Joules - The higher the joule rating, or MOVs, the more energy a surge protector can absorb before reaching its limit. A higher rating means better protection longer.
o Circuit breaker - When a circuit overloads, a breaker stops the flow of electricity (this is separate from surges and spikes).o Cost - Surge protector prices range between $10 and $40, the most common difference being how long they will last before they need to be replaced and manufacturer guarantee.
