Middle Atlantic's Series surge suppression is not new – but their Atlantic's Series Protection™ technology is, and it responds more quickly to a surge event than anything they have made before. This patent-pending technology provides instantaneous protection of AV systems from damaging surges and is available in a brand new family of power distribution units.


  • Industry’s fastest patent-pending non-sacrificial surge technology protects equipment from damage without contaminating system ground
  • MOV-free design is non-sacrificial and non-degrading
  • Connected devices are automatically disconnected (protected) from sustained over & under input voltage
  • Automatic recovery after an over/under voltage event minimizes system downtime (unlike devices that require hard reset after a surge event)
  • Half rack model – an industry first that requires minimum space without compromising functionality. Features flexible mounting options, for mounting behind screens or other space-restricted areas. Fits in the new HRF Series racks and on the back of VisionFrame™ monitor walls
  • Series Protection technology is available for the RackLink™ Power Management System
  • Series Protection technology meets the most current and applicable highest standard for safety and reliability. ETL and CETL Listed
