## Questions & Answers

**Q: what are the amps on the transformer?**
A: This is several months old now but I'm going to answer to help others because the other responses are wrong or were not helpful.  A volt amp or VA is 1 amp at 1 volt so 1 amp at 24 volts would be 24 volt amps.  So the common 40VA transformer = 40VA/ 24V = 1.67 Amps.  And a 75 VA transformer = 75VA/24V = 3.125 amps.  The transformer should draw less than 1 amp at 120V input and the output at 24 volts can provide as much as 3.125 amps if the load requires it. You can search for a volt amp calculator to verify my answers if you wish.

**Q: Where is the ground?  Also, which of the two black/Yelow wires go to the postive 24v  and which to the negative**
A: The transformer gets grounded by the mounting base and this is an AC output, so there is no polarity,

**Q: Security panel on 2nd floor - display bad - characters randomly display.  Current 40va transformer in basement.  Would 75ma fix this problem?**
A: Maybe, maybe not. Have you measured the supply voltage at your security panel with the problem?

**Q: is this UL approved and if so can i get documentation that it is. I may buy alot of them?**
A: It sure is.  I cannot put a link or a photo of the UL label into my response here though.  If you check the Functional Devices website, you'll see the UL.
