Here is my scenario. I have a 12v DC power supply capable of outputting 6A. I am using this to power a led light bar and small DC water pump. I also have a battery powered aerator (running off 2xD size batteries, batteries are in parallel)
I want to run this aerator from my 12V supply. To do this I bought a variable voltage regulator from Jaycar, put it together, verified that I can get 1.5v out of this device when it is connected to my 12V supply. Unfortunately this will not run the aerator motor.
I have measured the current in the circuit when the batteries are powering the aerator and it was approx. 250mA. When my voltage regulator is trying to power the aerator the measured current is only 7mA. So it looks like I am not getting enough current out of my regulator.
Is it possible to increase this current or have I done something wrong
Thanks,
Jason
