SURGE PROTECTION: Is Your AV System Truly Protected?

standalone483x303

Power surges take many forms — lightning, inductive-load switching, electrostatic discharge, and more. These unpredictable voltage transients can be catastrophic to today’s AV devices, which are highly vulnerable due to their internal microprocessing technology. This circuitry is incredibly sensitive and is not built to withstand sudden changes in current. With hundreds and even thousands of dollars of AV equipment on the line, surge protection is a vital and foundational element in any installation.

COMMON CAUSES OF SURGE & SPIKE EVENTS

SURGE PROTECTION: What Is SERIES PROTECTION?

Series mode protection is a more reliable and stronger option ideal for maximizing protection of expensive, sensitive AV components. Series mode protection’s internal circuitry leverages a large, high-current inductor that is followed by an energy-absorbing circuit that’s generally comprised of a bridge rectifier and capacitors. The series inductor slows the incoming current spike, which in turn spreads out the peak surge energy in the time domain and allows the surge to be harmlessly absorbed by the capacitors. With this design, series mode protection eliminates sacrificial design challenges.

In addition, some designs incorporate a capacitor bank that is always in circuit. In time, these capacitors will degrade. They are also susceptible to sustained over-voltage failure which causes a long term reliability problem.

If not replaced, capacitors can become leaky, or in some cases, fail completely. This is a well-known problem in the audio world, and audiophiles will “re-cap” their amps after a period of time. However, as part of the core for ensuring systems dependability, this is an expensive and inconvenient long-term solution.

Look for solutions that leverage Series Protection to its maximum capabilities, which has been engineered as the best way to manage energy. Middle Atlantic Products invested years of time and resources in its engineering and R&D teams. They went deep into the science of energy and series mode protection to discover ways it could provide a more reliable and enduring solution. The result is Series Protection, the industry’s fastest responding, long-lasting patented surge protection technology that benefits all AV components. Series Protection is designed to deliver superior series mode protection through two unique capabilities.

WHAT MAKES SERIES THE BEST?

1. Nothing is FASTER

Middle Atlantic’s Series Protection detects a surge event prior to the event moving all the way through the inductor. With a sensor placed before the series inductor, the system can detect, react and eliminate the surge energy at a near instantaneous rate of speed. As a result, there’s a faster response and events don’t reach a threshold where equipment can be damaged, like in a traditional series mode product. This also protects the unit, unlike the sacrificial design time of MOV surge protection and other series mode units that have to be replaced frequently.

2. Near ZERO volt load on Capacitors

To ensure the highest possible reliability, Middle Atlantic’s Series Protection disconnects the capacitor bank from the circuit under normal voltage conditions and connects it at the moment a surge event is detected a surge event takes place. This keeps the capacitor at near zero volts, ensuring a lower temperature, a longer life, and ultimately preventing leakage current from damaging the capacitor. It’s the only patented series mode protection solution that takes a systems approach to protecting sensitive AV systems while also preserving your investment in power protection.
