Electrical Engineering Asked by Boann on October 29, 2021
I’d like to use an old laptop AC adapter in conjunction with an adjustable buck module as a project power supply.
It works, but I’m ignorant of some safety details; for example I’m uncertain whether my adapter, which uses a non-earthed input, is "isolated from the mains".
I’ve tried researching the symbols on the label, but one symbol which feels relevant I cannot identify:
What is that letter T in a triangle?
Does it mean "safe"?
Or "death"…?
Older symbol for Japan's Product Safety Electrical Appliance & Material. Replace by the second symbol.
