Spikes/surges are common in every house, office and building. The intensity varies and you never know when that killer spike will occur. Even milder spikes will gradually degrade the reliability of your equipment by repeatedly blowing microscopic holes in electronic circuitry until the equipment is rendered unreliable or non-functional. Data is particularly at risk. Noise & RFI (Radio Frequency Interference) are also abundant and can cause serious harm to data. The Sollatek PureAC is extremely simple to plug and connect and will provide full surge/spike, noise & RFI protection. Available in 3 size (3, 7 and 13Amps).
