Advice on these Chinese DC - DC converters?
March 14, 2012
SO, I got a couple of these 80w DC - DC buck converters to supply power to Houston. One is going to be the 5 volt supply for the servos, the other is going to be a 7.2 volt supply for the Rover 5. Last night I got a motor out and adjusted them to the proper voltages.
The thing that's got me confused is the "constant current" part. There are two multiturn pot type adjustments. When I ran the motor, it pulled about 350ma turning the current pot didn't seem to change anything.
I have a similar 100 watt boost converter that will be supplying power to my SBC at 18v 5a. I figure I can connect a 100w 4 or 3.5 ohm resistor to that one and make sure it works safely, but I'm not sure how to go about setting these up to power an arduino, a D4CMC, and some servos.
Here are a couple of pictures
