I'm trying to put together a CIP system, and am using a NorthStar Pump that draws 10A at 12V. To power it, I ordered a 12V 10A AC/DC power supply from Amazon. However, when I connected the power supply to the pump, the power supply immediate shuts off, as if it was overloaded.
To troubleshoot whether the problem was the pump or the power supply, I connected the pump to a 12V 10A motorcycle battery, and the pump operated as expected. While the battery was connected, I inserted a multimeter and found that the pump starts at a low amperage (~4A), and ramps up to around 10A. (typically around 6-7A, though it very briefly hit 10.9A once)
I verified that the power supply is delivering 12V, but couldn't verify the amperage, since it shuts down immediately when the circuit is connected. But with the voltage being correct, it looks like it can't handle the amp requirement, despite being rated for it.
I'm curious if anyone else has run into similar problems? What power supplies are people using for their pumps? Any suggestions?
Thanks,
