SS-6B-PRO Features at a Glance 6 Outlet block Heavy duty steel construction 15 foot power cord Illuminated ON/OFF switch Circiut Breaker EMI/RFI noise attenuation Extreme Voltage Shutoff Overvoltage 140VAC +/- 7 VAC undervoltage 95 VAC +/- 5VAC The SS-6B-PRO adds Extreme Voltage Shutdown to the venerable SS-6B for exceptional performance and protection. The SS-6B-PRO is a 6-outlet power block with standard level surge suppression protection EMI/RFI filtration Extreme Voltage Shudown (EVS) heavy duty steel construction and a 15ft. Power cord. The EVS provides over/under voltage protection and will automatically turn back on once the incoming power has stabilized.
Another great value of the EVS circuit is that not only does it protect the connected equipment the EVS also protects the SS-6B-PRO making a sacrificial situation highly unlikely.
