I have a 12volt 3amp DC water pump with an ac to DC power supply rated 12volt 8amp 96watts, connected with 75 feet of 12 guage wire.
The power supply when not in use reads 12.3volt output, but when connected to pump voltage fluctuates 14-20 volts. I've tried connecting a DC to DC buck converter rated 9-36volt input and output of 12volt 5amp 60watts, but then the voltage output with pump running reads 9.xx volts and the DC male to DC female adapter after power supply started to smoke some.
Should I just not use buck converter, or what would be the proper buck converter/voltage regulator to use???
