The ETA-PD8A 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 incorporated to reduce noise from Electromagnetic Interference (EMI) from such items as electric motors and switching power supplies. The benefit of these filters can be seen on video products or audibly by reducing static pops and external signal interference.

The ETA-PD8A is unique in that the integrator can select the power cord length that is required for the installation. A removable 12' IEC power cord with a retainer bracket is supplied with the unit. A shorter or longer cord can be purchased separately if needed.

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-PD8A’s circuitry is very fast and can suppress unwanted energy within a nanosecond response and sustain the suppression up to 2 milliseconds, thus ensuring virtually trouble free protection. The front panel also features AC fault and ground status indicators providing quick, visual reassurance the equipment is safe.
