Why does electronic equipment (home theater etc.) need more protection than everyday appliances?
Electronics devices operate from an internal dc voltage that is derived from the incoming ac voltage using a rectifier and energy storage capacitor. Disturbances on the power line can reflect into dc voltage anomalies that can damage this power input stage. Electronic devices also use sensitive digital electronics that can be damaged or put into ‘phantom’ states by power disturbances. 6. Why don’t manufacturers build power protection into their products so we don’t need external devices? Manufacturers design equipment for ‘nominal’ industry-standard line voltages – 120 volts +/-10%. Designing for a wider range is expensive and puts them at a competitive disadvantage. Also, designing fail-safe power protection adds cost that puts them at a competitive disadvantage. Finally, power protection is designed to be sacrificial in case of a worst case hit. If the power protection is inside the equipment, one would still have failed equipment. 7.
