I have a winch that I would like to supply with a DC switching power supply. The winch has a current of approximately 40A at 24V under the specified load, but the inrush current will be much higher, I think over 100A. What I would like to use as the supply is a 24V, 100A switching power supply, which has a current limiting function and will shut down after 5s of overload. Since the inrush current will settle down to the nominal current in no time, I think the power supply could handle this. Am I right?
According to the datenblatt, the PSU is programmable to either deliver constant current, or to deliver constant current and then shutdown after 5 seconds. So it looks like you need not have a problem with shutdown if the winch doesn't accelerate fast enough.
The inrush current from an unlimited supply may well be very high, but as your PSU has a current limited output, that will define your starting current. This means the winch will have a lower starting torque than would be expected for starting from a battery.
As the specified load takes 40A, then at a limited 100A, you will have up to 6.25 times the rated load torque for starting, or less if either of your armature or stator saturates at 100A.
