Middle Atlantic Series Protection(TM) Compact Surge Device Receives U.S. Patent

FAIRFIELD, N.J. — Oct. 14, 2015 — Middle Atlantic Products today announced that its Series Protection(TM) technology has been awarded a U.S. patent, recognizing innovation in its series-type surge-suppression capabilities. The company’s Series Protection Compact Surge Device now offers the fastest-responding technology in the most compact stand-alone surge-protection appliance in the industry.

The Series Protection system is engineered with nonsacrificial and nondegrading protection to ensure system reliability by effectively absorbing surges without contaminating the system ground. It safeguards against both under- and over-voltage events, with automatic recovery that does not require a hard reset after a surge event — a feature that minimizes system downtime.

Patent US 8947844 B2 addresses the design of Series Protection technology, which is capable of detecting a surge event before the voltage spike reaches extreme levels, resulting in unprecedented response time. The technology’s energy storage capacitors are also kept discharged or minimally charged under normal voltage conditions to provide significantly increased reliability. 

“The patent for our Series Protection technology reaffirms Middle Atlantic’s commitment to innovation for the benefit of our customers and ultimately the end user,” said Keith Carney, VP of engineering and quality assurance of Middle Atlantic. “Integrators rely on our products to make their lives easier. This patented, ultra-compact surge device offers protection for installations where space is at a premium, making it ideal for discreet placement behind flat-panel displays.” 

Middle Atlantic offers more than 350 power products and was recently awarded another patent for its IsoCenter(TM) Series Isolation Transformer. Both patents recognize the company’s power innovations, providing integrators with an unmatched level of protection that helps ensure system reliability and longevity.
