Hello for the converter in the link above when converting AC to DC should I have both inputs to the same AC source or do I just need one output connected? I have used the above with DC to DC successfully but I don't want to damage the component with an AC source. The two input wires are not shorted together. And I appologize but I was not able to find the datasheet for this converter.
The linked page says the thing can accept 16 - 40 Volts DC or 16 - 28 volts AC input. Apply your supply voltage (AC or DC) across the two input wires. Since it can take an AC input, polarity doesn't matter when using DC.
