You may have a number of expensive home electronic devices in your home, including a TV, Home Entertainment System, Audio Systems, PCs. Are you protected if a power surge occurs on your mains electricity supply?
If you need additional power outlets you go off to your local hardware store and purchase a power strip with maybe 3, 4 or 6 outlets. Do these surge strips have surge protection features enabled, or are they merely extensions?
A typical 4-way surge protection device might cost you £10-15 in your local highstreet store, but online you can purchase a surge strip for as little as £5-6. That is not much to pay when you consider that it might protect your pride and joy, that brand new 46 inch HD TV, or your £1500 home entertainment system you treat yourself and your family to.
Sudden increases in voltage on your mains power supply come without warning and if they are of sufficient magnitude they could severly damage unprotected electronic devices. A surge protection device will harmlessly route the excess voltage to ground, normally through the use of a MOV (Metal Oxide Varistor). The MOV typically consists of two variable resistance strips which decrease in resistance as an increase in voltage occurs. The least resistance path is to ground, so the energy is dissipated harmlessy.Once the voltage returns to normal, the resistance of the MOV increases and current flows normally to your attached equipment.
Some surge protection equipment even has additional outlets for telephone line and cable connection, therefore protecting any equipment connected via the telephone or cable.
It really is worth the investment of a few pounds to protect your most treasured home consumer electronics products.
