Please explain more, I didn't get what you mean exactly.
Do you mean, if I; for example, used this PSU output pins which provide DC voltages 3.3, 5 and 12 volts, there will be inrush current, which will pull a high current and then blow the PSU fuse ?
Yes. If there's a short circuit on the output the light bulb is not going to help you. For example.
Okay the power supply Max output voltage is 12 volts at 275 watts.
Maximum output current is Watts divided by volts.275÷12=22.916Amps.
Now you just bought a 12 volt 275 watt light bulb because you're going to use it as a load on your output just in case there is a short circuit the output will see a load? maybe?,that 22.916 amps is what the light bulb will draw when it's hot with a resistance of
0.524 Ohms (rounded up)when it's hot!
Rule of thumb is 10 times...so in this case it is 10 times less resistance.
0 0524 Ohms when the light bulb is cold. 12 Volts ÷ 0.0524 Ohms =229amps . That is your in-Rush current the cold light bulb is going to draw(That will never happen). That is overcurrent and that will trigger overcurrent protection circuitry whatever that may be. My point is if you're going to use a incandescent light bulb as an output load resistance keep in mind the difference between the light bulbs cold resistance and hot resistance of the element because it takes several milliseconds for the bulb to heat up and if there's a short circuit on your output the short circuit current could be 10 times greater than the rating of the light bulb. Whatever light bulb you get make sure when you "ohm it out" (measuring the cold resistance), it's at least 0. 524 ohms and you'll be okay. I have used incandescent lamps as a load and still do...
