ETA-S20
AC Power Distribution Unit & Surge Suppressor
INTRODUCTION
Thank you for purchasing the ETA Systems ETA-S20 AC Power Distribution & Surge Suppressor Unit. The ETA-S20 has been designed
to meet most installation requirements for AC power distribution and equipment power protection.
The ETA-S20 features noise filtering for unwanted Radio Frequency Interference (RFI) that is commonly introduced into AC lines by
nearby radio transmitters or wireless products. The benefit of these filters can be seen on video products or audibly by reducing static
pops and external signal interference in sound reinforcement systems.
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currentpeaksof3000A.Thesespikesareveryfastandusuallyonlylastfora
very short period of time. The ETA-S20’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. If the suppression circuitry is damaged, the
AC Protect LED will turn Off to indicate a fault has occurred.
The ETA-S20 offers power management control, noise filtering, and protection against abnormal voltages, spikes, and surges.
