## Questions & Answers

**Q: Need 5vdc out, input varies 7-15vac...will it regulate at 5vdc out or will it be proportional to varying 7-15 input**
A: They are very precise about the output.  I used on with 12 v input and 5v output for an arduino.  When I connected it to 24v - still, exactly 5v!

**Q: Will this modual go from 12v ac in to 3v dc out ?**
A: Yes

**Q: Is there a UL Listing for this?**
A: You don’t need one. If you’re going to embed this into a system then the system gets UL approval.
That’s the point of an embedded system.

**Q: Can this convert 24v ac to 24v dc or will there be a drop across the device?**
A: This conversion broad has worked great for me.   My demands are not great , I can get the DC voltages I need.  I recommend!
