This power source has three outputs, and it will work with any LEGO remote control (with a LEGO infrared receiver) or SBrick.  The three outputs are:
  1. Always on: like in the original version of our PF power supply, when your PF battery is on, the lights connected to this port are on
  2. "On When in Reverse/Left": lights and effects connected to this port are turned on when the PF channel the power supply is connected to is put in reverse or turned to the left (for example, on the LEGO IR remote, when the orange wheel is turned to the left)
  3. "On When Forward/Right": lights and effects connected to this port are turned on when the PF channel is put in forward or turned to the right (for example, when the orange wheel on the LEGO IR remote is turned to the right)
The photo below shows the ports as they are located on the power supply circuit board.

Using this power supply, it is now possible to create a number of new lighting and effect setups, including:
  • Directional headlights on trains
  • Automatic reverse lights on vehicles
  • Individual control of building or other lighting using a LEGO remote
There are some important points to keep in mind about this power supply:
  • It will not operate with LEGO 9V transformers or trains.
  • Outputs are not dimmable-- they are either on or off.
  • When using with an SBrick connected to the same channel as a motor, both the forward and reverse outputs will be activated when the motor is moving slowly.  When the motor is operated at high speed in either direction, this problem goes away and only the correct port is activated.  This is an issue with the way in which SBrick controls motors, and it not related to the Brickstuff power supply.  When used with a LEGO infrared control system, this issue does not occur.
The power supply has three red indicator lights as shown in the photo above.  These indicate when a given output channel is activated.
The following illustrations show several configurations for the power supply.  All configurations work with SBrick ports as well (though note the SBrick behavior above when connected to the same channel as a motor).


1. Dedicated Connection to One Power Functions Channel
Picture
 (as you can see in the above illustration, Brickstuff lights and effect controllers can be connected to any of the outputs on the power source.  This allows lighting effects to be triggered by a LEGO or SBrick remote)


2. Connection to Channel With Motor
Picture
 (in the illustration above, directional headlights are created by connecting the power source to the same Power Functions channel as a motor)


3. Connection to Channel with Servo
Picture
 (in the illustration above, a the power source is connected to the same Power Functions channel as a servo-- when used with our Flashing Pico LEDs, you can create automatic turn signals for vehicles.

The scenarios above are meant as a starting point-- the power source is flexible enough to be used with almost any Power Functions configuration.
