The ETA-PD8LA was designed to be flexible with features that allow it to be used in a variety of applications. The ETA-PD8LA can be used solely for protection against voltage surges or for AC distribution. The unit includes seven rear panel switched outlets and a single unswitched outlet as well as the circuit breaker reset switch. The front panel includes a single unswitched outlet as well as a pull out LED lamp.

The integrated AC power conditioning is designed to eliminate or reduce fuzzy video or static pops that can be the result of unclean power.The ETA-PD8LA features noise filtering for unwanted Radio Frequency Interference (RFI) that is commonly introduced into AC lines by nearby radio transmitters or wireless products. EMI filters are also incorporated to reduce noise from Electromagnetic Interference (EMI) generated by items such as electric motors and switching power supplies.

Unstable AC Mains voltage is one of the main reasons for equipment failure. The amount of energy that can be injected into the power system can be immense with voltages reaching 6kV or amperage peaks of 3000A. These spikes are very fast and usually only last for a very short period of time. The ETA-PD8LA's circuitry is very fast and can suppress unwanted energy within a nanosecond response and sustain the suppression up to 2 milliseconds.
