Power surge is a very brief spike in your power TV or cable line. It can be caused by thunderstorms, changes in the power load from appliances going on and off, problems with your local utility company and more. Why worry about power surges? The investment you've made in your home entertainment system, not to mention your home, can be wiped out in an instant. At a minimum, surge can reduce the lifespan of your equipment. How does surge protection work? In a power surge, excess energy is absorbed by a component called on MOV (Metal Oxide Varistor). This component absorbs excess energy and releases that energy as heat. If the MOV is overloaded, there can be sparks and fir. What is joule rating? This number represents how energy an MOV-based surge protector can absorb in a single event, without failure. Higher joule ratings indicate greater protection. Just Power It Up by Monster gives you the easy and safe power protection you need, backed by Monster's 40-year history as the power expert.
