[QUOTE="el bandido, post: 1087910, member: 316102"] We are not building a nuclear bomb. We just want to move a satellite dish. When I first got the Prodelin, I tested several different positioners and found they all act similar. A VBox may say it is rated at 36 volts dc and 3 amps. This would be over 100 watts of power for the actuator if the thing could hold at 36 votls and pull 3 amps. The reality is the dc voltage drops rapidly, and you will end up with something like 3 amps at 20 volts dc, then you may see 4 amps at around 15-16 volts dc as the load is increased. So more or less, the power output in watts is the same, even when the amperage is increased. As for reliability, I burned up a couple of the V Boxes testing them, and I agree, circuit design is important. But these amperage ratings we have seen for these positioners do not mean much.
