There is a limit to the amount of current that an active busboard can supply, and this depends entirely on how much current your modules draw.
With some set-ups you will be able to easily run three rows from one active module (1 active + 2 passive).
If you have very power hungry modules in your set-up, then you may need an active busboards on every row.
A good middle ground starting point is to have one passive module per active module.
If you need more power, then you can easily upgrade any passive busboard to an active busboard.
Simply remove the Quick-Clip-4 cable connecting it to any other active modules on the right hand side, attached a Quick-Clip-2 cable to supply 15V DC on the left hand side, and install the 3 Active Modules in their respective sockets on the busboard.
**GIF of removing 4-core cable, connecting 2-core cable from daisy chain, installing active modules, then powering board.**
Remember to match the the correct module with the correct socket and orientation. For example make sure the +12V module goes in the socket marked “+12V” and the -12V module goes in the socket marked “-12V”.
- If the red LEDs on the Active Modules are lighting up, but not the green LEDs on the busboard, you may have installed the wrong module in the wrong socket.
- If none of the LEDs are lighting up, then you may have either installed the Active Module the wrong way round, or improperly in the socket.
