Power - The Switched Mode Power Supply
The Eurorack SMPS is a powerful, lightweight and safe PSU for your Eurorack portable system.
It's able to deliver 1.25A per rail (+12/-12V).
The front panel only takes 4HP and hosts both the DC input jack, the main switch and 2 LEDs for +12V and -12V.
This PSU also includes on its input a reverse polarity protection, a over-voltage protection (transients, wrong input voltage etc) and a fuse in case something bad happened.
