Set the voltage using your multimeter on the lighting buss or individual building. These modules will power more than one building depending on the number of leds in each building. If a single led draws 20mA, a 2.5A module will power 100+ leds.
When I posted I mentioned 1/10 of 1 volt makes a huge difference. I found it easier to dial it in with a micro screwdriver without holding meter leads on terminals while screwing.
one nice thing about the built-ins is that you can move the display value up or down if your looking for round even numbers. I calibrated mine to my fluke actual outputs.
It is kitchen table easy, looks cool to the visitors & blows them away when you tell them you built it. You’ll be impressed with yourself also.
