Pedal Power
The P2 is a pedal power module that produces up to two times 1000 mA off 9V power intended to power pedals from your case for easy integration with eurorack systems.
The main limitation of power out from the P2 module is how much current you can draw from the +12V rail in your system. Be sure to check that your eurorack system can supply enough current through this module to the pedal or other equipment you are powering with the 9V from this module.
If you connect a pedal to the 9V out that needs 100 mA the module will draw 100 mA from the +12V in your case. The modules will use the same amount of mA on you +12V as the load used on the 9V side all the way up to maximum load of two times 1000 mA.
These merchants probably sell this module. Huh?
