power supply hums when electric blanket on
When I dare to use an
A) electric blanket, or a electric frying pan set on "low", at the same time when there is a B) UPS computer power supply, or Ham radio power supply also turned on anywhere in the house, the power supplies hum most worryingly. One must make a choice: A) food, warmth, or B) fun. What is the name of this waveform resonance with the current limiters of A phenomena? Is there some kind of filter I can apply? |
