Power Source

Postby Ger15 » Thu Nov 15, 2018 1:22 pm

Ok this is probably a stupid question but anyway I’m currently wiring up my dash 2 and sensors which are Race Technology sensors, Has the power supply to these sensors be 5v or 12v ? The packaging says 5v but when looking it up online it’s saying 12v so not sure which to fit with thanks

The wheel speed sensor connects to 12v, the others all connect to 5v.

Hi...there are power management chips from companies like Maxim with multiple outputs, although your current draw requirements means that any such monolithic chip will require augmentation with external transistors, etc.
Bear in mind that you're asking for 300W PER OUTPUT, which is not going come in a small form factor, given, say 10% efficiency, and 3 outputs, the box has to dissipate a minimum of 90W on its own.
