The Excalibur powerline surge filter is a two-port device, and it has a single switched mains input and eight parallel-connected outlet sockets on the rear panel. These provide the power to the equipment that requires protection. A circuit breaker is provided on the rear panel, and this will trip if the total load connected to the outlet sockets exceeds 20A. The circuit breaker is of the re-settable type.

A front panel display allows the user to monitor the electrical parameters of the total connected load, and there are values displayed for:

  • Voltage
  • Current
  • Power
  • Energy
  • Frequency
  • Power Factor

To connect the Excalibur, follow the steps listed below:

  1. Using the supplied AC mains power cord plug, the cable into the power inlet socket on the rear panel and then insert the plug end into a suitable wall outlet mains socket.
  2. Using the individual power cords for the equipment to be protected, plug each item into one of the rear sockets on the Excalibur. There are eight in total.
  3. When everything is connected, the power can be turned on using the main switch on the front panel of the Excalibur. The switch will illuminate when the power is on.
