Zero Crossing Detection
Without getting too technical, electricity flows to your equipment as an alternating current (AC), constantly switching between negative and positive cycles. Switching power at a peak point of the current cycle can create stresses to relays and components.
This happens extremely fast but the amazing AVC014 IntelliPlug determines when the voltage is in the middle of the positive and negative extremes, called zero-crossing, to introduce power to your equipment at the optimum point which is when no voltage is present.
This not only minimises wear of components in your equipment but vastly extends the potential life of the IntelliPlug to an estimated 1,000,000 operations.
