I have a 12v DC Fan made by SPAL. It is rated @ 40amps. The fan is used in cooling a radiator on my engine dyno. The fan cycles on and off about once per minute for 10 minutes at a time.
It is currently drawing power from a car battery which is connected to a 2.5 amp battery tender. I wanted to eliminate the battery and tender and use a AC to DC power supply. So I bought the venom ps600 40 amp power supply.
The problem is that the power supply goes into protection mode as soon as the fan turns on. Turns out the ps600 has an over current protection circuit.
Can someone explain what I need to do to either bypass the protection circuit or reduce the inrush current of the fan?
Thanks
