12V power supply for roborio

[juchong]

In past years we've used the power adapter included with the D-Link radios as a power source for cRIOs/RoboRIOs.

IIRC the D-Link took 5V and the cRIO took 12-24V. That doesn't sound like a good combination. Do I remember incorrectly?

We have a 12V power supply we use to test both the cRIO/roboRIO for programming and the entire robot if we are doing long bench tests and don't want to have to keep switching batteries.

I'm thinking about getting one of these for our benchbot

Supposedly 12 100 AMP - Put the normal connector on it (Anderson? ) and use it through the pdp just like it was a battery. I'm thking 100 AMP would be enough even to power 2 CIM's if they have no load on them right?

According to Andymark, a CIM motor's free current is 2.7 amps. That is if it has absolutely no load on it. 100 amps will be more than enough to power 2 CIM motors at free speed. The problem comes when you attach them to gearboxes and wheels. I'd still say with a properly geared gearbox that you're pretty safe doing a 2 CIM drive off a 100 amp power source.
