The Slim PSU is a simple +/-12V design that can supply 500ma for a single panel. These PSU power busses can be daisy chained from one Mean Well brick allowing less clutter and easier setups between multiple panels.
The Slim PSU can power up to 12 Prism Circuits modules.
Once PSU is completely built you can probe the corresponding voltage pads with your multimeter and adjust the trim pot until the voltage output reads +12V and -12V. You are now ready to install power in your case.
