Current Spike in a power supply...
Current Spike in a power supply...
(OP)
I have a power supply running 60 amps to the load.
What are the chances of lightning(storm)creates a huge spike in the load.I checked the load and it was destroy, butthe power supply is working ok.What causes this spikes in this power supplies.





RE: Current Spike in a power supply...
Tell us more about your load.
Tell us what part of the country you are in.
What kind of supply is it?
How is the load hooked to the supply?
How is the supply wired to its source?
Then we can get pretty specific in our help to you.

Is a sorensen power supply that can supply 120 amp but I only supply 60 amps to semiconductor diodes connected in series..... But sometimes goes to a max current and this destroy the load..
RE: Current Spike in a power supply...
A power supply fault, whether transient, intermitent or continous, or a power line transient may result in a voltage spike to the load. This may destroy the load or the diodes, and high current may be the result rather than the cause.
You will notice that I have used the word "may" several times. You have not provided enough information for the power supply experts like itsmoked to give a more definite answer.
respectfully

If so, are the wired to somewhere?
Tell me more about the load. Two diodes in series as a load makes no sense to me. (yet)

Setting the current limit on the supply to about 70 amps
should save the other diodes if one fails. If your load
is diodes then the voltage drop should go lower when they
heat up and then the supply will give more current,then
the diodes heat up more and so on.If I understand your load correctly.
