ACT Communications AC Surge Protection Devices (SPDs) 471


ACT offers real-world solutions to all of these power quality problems.

Since the late 1980’s, the industrial markets like water treatment, schools, prisons, refineries and all types of factories, has been transitioning over from an electrical environment to a purely electronic environment. This electronic environment includes not only specialty equipment like Industrial Control Panels, Robotics, Computers, Printers, but also includes Facility Alarm & Security, and energy saving devices such as lighting ballasts and Variable Frequency Drives.

This means that equipment failures can be caused by anomalies that originate from outside and inside the industrial facility. Not only is the electronic equipment more sensitive from outside transients, but their power supplies generate high frequency noise that will hurt other electronic equipment tied to the same power bus.


  • No other protection company is offering this breadth of power filtering and monitoring capability in a single package.
