Choose Best APC P11U2 and BE425M Surge Protector + Battery Backup Bundle
Overvoltage protection devices provide the best surge protection, and selecting the right protection devices can significantly protect sensitive electronics such as computers, stereos and home theater devices. Fortunately, you do not have to be an electrician to make an informed decision. People just need to know the difference between a multiple socket and a surge protector, how to understand the different levels of protection that various surge protectors offer, and some additional features that are also useful.recommend APC P11U2 and BE425M Surge Protector + Battery Backup Bundle
Which equipment does the surge-protector need?
Any device connected to a power outlet can benefit from over-voltage protection. The most vulnerable teams are those with memory and sensitive electronic circuits. Surge protection is essential for: PCs and peripherals such as printers, monitors, and routers. Televisions, DVRs, cable boxes, satellite receivers, sound systems and other components of home theater systems. Lighting, tools, small appliances and office equipment. Note: If you need to protect a computer, consider using an inverter that provides surge protection and battery backup to keep your computer running in the event of a failure.
To select the best surge protection for your computer and other devices
Most people have lost a device or electronic device because of an outbreak or lightning, but high-quality surge-protectors can help protect your valuable equipment from possible damage (and believe me, there will be a neighbor).
For maximum protection, it is important to choose the best surge protection for the equipment concerned. And when it comes to surge protection, the "best" is not automatically the most expensive.
Some high-end models offer less real protection against over-voltage and light loss than some of their cheaper counterparts.
Before I go into detail what to look for in a surge-protector, I'll briefly explain the difference between a surge-protector and a standard power strip. I recommend that you replace your surge-protector immediately after the power supply in your home has been touched by an increase or a fire, even if the unit shows no obvious signs of damage. And if you live in a storm-prone area, it's a good idea to replace them every year after the end of the storm season.
How does a surge protector work?
When the voltage exceeds the allowable level, the surge arrester removes the surge to avoid damage. In particular, internal components, called metal oxide varistors (MOVs), absorb the excess voltage and redirect it to the ground wire, preventing it from reaching the connected equipment. To work effectively, a surge-protector must be plugged into a grounded, wired outlet. Some surge-protectors contain indicators that alert users to possible wiring problems.APC BE425M Protector Battery Backup You can check price APC P11U2 and BE425M Surge Protector + Battery Backup Bundle
