One of the disadvantages of much electronics is finding enough chips to connect everything together. For a desktop computer, you may need additional jacks for monitor, printer, desktop speakers, wireless routers, mobile devices, and other devices. For a home theater system, there are televisions, stereo receivers / amplifiers, preamps, subwoofers, speakers (sometimes), turntables, DVD / Blu-ray players, game consoles, and cable set-top boxes.recommend P3 INTERNATIONAL Save a Watt Phantom Power Indicator
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.
Where Do Power Surges and Voltage peaks come from?
Lightning is known to cause outbreaks. However, power surges can also come from high-power devices that are on the same circuit. These can generate powerful spikes in the power line when turned on and off.
For example, if you have a refrigerator or air conditioner in the same line as your computer, you may experience interference that could damage your computer. Sometimes it can be an unexpected restart. However, it can also cause hard disk crashes that can not be recovered.
The medium overvoltage protection does not protect your radios. If this is a major problem in the area where you live or work, you should consider complete protection of the construction with an external lightning rod that deflects the lightning rods to the ground.
If you are worried, contact your energy company and telephone company. Ask them what precautions they have taken to protect you and what features you have when lightning strikes.
You have options to protect against outbreaks. They include over-voltage protection, protective strips, a backup battery or surge protection on the wall. Most surge protectors use MOVs, a type of variable resistor. MOVs are low voltage resistant, so they do not conduct electricity during normal operation and allow the current to flow directly to the connected equipment. When subjected to a higher voltage, the resistance of the MOV decreases and begins to move the current away from the connected equipment. Overvoltages cause the MOV to wear, causing over-voltage protection to lose its protective function over time.P3 INTERNATIONAL Phantom Power Indicator You can check price P3 INTERNATIONAL Save a Watt Phantom Power Indicator
