[RE-wrenches] battery box fan

[Larry Brown]

Wrenches.

On an upgrade to an existing system, we just installed a Xantrex  
XW6048 inverter.  We have a 48 volt dc battery box vent fan that we  
used to run through the relay on the old SW5548.  The XW6048 has a 12  
vdc aux output so I assume we need to install a relay to run the fan,  
12vdc input, that will allow 48 vdc output
Any suggestions on what relay to use?

Thanks
