Low voltage -> High amperage -> Exceeds component thermal capacity -> component failure.
It does not happen in electronics. It only happens when wild speculation invents fears. Otherwise we have read numbers that justify that wild speculation.
We, who actually do this stuff, routinely verify damage cannot happen. For example, one peer
(Tom MacIntyre
) demonstrates:
> We operate everything on an isolated variac, which means that I can control the voltage going into the unit I am working on from about 150 volts down to zero. This enables us to verify power regulation for over and under-voltage situations. ...
Switching supplies ... can and will regulate with very low voltages on the AC line in; the best I've seen was a TV which didn't die until I turned the variac down to 37 VAC! A brownout wouldn't have even affected the picture on that set.
Die as in power off; without damage.
Demonstrated is what the informed know and do . We actually do stuff. Do not post wild speculation as if it proves anything:
Low voltage does not damage electronics. Low voltage is a threat to less robust appliances: ie central air, refrigerator, vacuum cleaner, furnace.
Only wild speculation claims damage. By posting subjectively - also called a lie.
International design standards
(long before a PC existed
) said all voltages down to zero must cause no damage. One standard was so blunt as to write, in all capital letters, across the entire low voltage area: "No Damage Region."
He operated that 120 volt TV even at 37 volts before it powered off. Without damage - since international design standards demand it. International design standards do not make claims from wild speculation. Reality is based in and demonstrates by numbers.
No datasheet and no number was cited because low voltage does not do that damage. Only lies from wild speculation promote that fable.
