Each of these ETA power conditioners contains three important elements — a high-energy surge diverter, a low-impedance isolation transformer, and a power line noise filter. ETA’s integrated design provides a high-performance solution to ensure the cleanest power possible for digital audio or video workstations, mixers and digital signal processors. Our special low-impedance transformer design guarantees all the current needed for a high-powered audio system even when sudden dynamic changes result in greatly increased demand for current. Each of these power conditioners will withstand a worst case power surge of up to 6,000 volts and safely reduce it to less than 10 volts between hot and neutral and less than .5 volts between neutral and ground — the precise electrical environment demanded by high-performance digital systems.
