List Members, Thanks for all the great replies! Would it make sense to see if the end product can pass safety with the non-LPS power supply? Is the the LPS clause just a CB scheme requirement or is it required for NRTL approval also? Best regards, Christine Rodham

They recently changed vendors to another power supply with the EXACT same rating Except it was not marked as a LIMITED voltage power supply. Our supplier says this is not a compliance / safety issue because both supplies are recognized by UL and have the same voltage and current rating. So the $64,0000 dollar question is can you use a non- LPS in place of a LPS if they have the same rating? Thanks in advance, Thank you in advance!
