PDB 24V keeps dying
 

The 24V ports on our PDB keep dying. The green LED stops lighting up after seconds of running our robot. So far we have 3 broken power distribution boards....:mad: An ideas why?

Re: PDB 24V keeps dying
 

Do you drill over your robot causing them to short out often?

Re: PDB 24V keeps dying
 

nope. This is our third PDB and I just changed it 10 min. ago. drove for about a minute and it stopped

Is your Crio electronically isolated from your frame?

Re: PDB 24V keeps dying
 

the whole electronics board is on lexan.

Re: PDB 24V keeps dying
 

Yes but lexan can still carry a current for approx. 4-6in. When mounted directly to the frame.

Re: PDB 24V keeps dying
 

what would you suggest for me to do ?

Re: PDB 24V keeps dying
 

When you touch the robot do you might get shocked but when you touch say a bolt on your lexan board do you get shocked? If so you need to isolate your board.

heres a picture

Re: PDB 24V keeps dying
 

nope not getting shocked.

Re: PDB 24V keeps dying
 

Garten, I'm very confused by several of your responses in this thread. Do you have data to support your claims that Lexan can conduct electricity 4-6 inches and that the voltages on the robot are sufficient to cause noticeable electric shock?

Jsasaki, verify frame isolation with a meter. Then, check the insulation on the wires coming off the right hand side 40A breakers - you may be shorting there.

It would be nice to see the other end of the four pin connecter.

Re: PDB 24V keeps dying
 

Also, those wires touching the Crio from the jag in the upper right corner at touch the Crio and those are getting power.

Re: PDB 24V keeps dying
 

Looks to me like the wire on the 5 volt camera plug is a little long.. Either that, or it's something blocking my view..

Re: PDB 24V keeps dying
 

Yea I saw that too.
