Is your A/V equipment completely protected against damaging surge energy? That’s what Zero Surge wants to know, as its products incorporate Total Surge Cancellation (TSC) technology to entirely cancel damaging surge energy from protected equipment, not just suppress the surge to a lower value, the company says.
TSC first filters off the most dangerous surge frequencies and then cancels the remaining residual surge voltage, Zero Surge says. Here’s how the company explains it: When the TSC filter encounters a transient surge, the surge is filtered and delayed. At the same time, an auxiliary winding develops a canceling voltage, which is generated from surge current flow in the transformer. Adding the canceling voltage to the delayed residual surge voltage prevents any residual surge voltage from exceeding the power wave peak voltage, reducing the surge voltage let-through to zero. The damaging surge energy is totally removed.
TSC power quality filters are certified to withstand up to 1,000 of the worst case category-B surges, which measure 6,000 Volts/3,000 Amps, says Zero Surge, which adds that according to the American National Standards Institutes’ report on the typical surge environment (ANSI C62.41), 6,000 Volts/3,000 Amps power surges can occur up to 100 times per year, meaning the technology has a minimum 10 year life.
