ProteK Rack 8 + 1
The front panel of the PR-81B displays the voltage coming from the AC outlet that the PR-81B is connected to as well as the current draw of your connected devices.
Power surges can originate both inside and outside the home. When your home loses power or the power company performs a
grid switch can cause a surge or power in your home. When higher power devices, such as an Air Conditioner, hair drier, or electric oven are turned on and off can also cause a spike of voltage throughout your homes electrical system.
The status indicators on the PR-81B let you know when yourconnected equipment is protected, if the AC outlet the PR-81B is connected to is properly grounded, the correct polarity, and if unsafe voltage is coming from the wall.
