CCFL inverters question

Johnny · Post by **Johnny** » Sat Jan 24, 2004 7:36 pm

Ive purchased the mx222 rev 1.4, i wish to connect 3 case fans, three inverters for 6 CCFLs. is it possible with the current GPO setup or does it require modification??

Can the low power GPOs support any of these items. I would like to control the 3 inverters for my CCFLs on separate gpos as they are different colours.

But, can i wire two inverters onto one GPO (spec of inverter below)
Can i wire all the standard case fans together onto one gpo?

Specifications of Inverter
Input Voltage = DC12V
Input Current = 0.6A
Output Voltage = 1.2KVrms
Light Current = 5mA
Frequency = 40+/-5
Load = 2 x 300mm CCFL

thanks

With Revision 1.4 there are only three high powered GPO's. Each GPO can handle up to 1000mA of current. You can connect more than one fan per GPO as long as you stay within the given limitations. With just three fans, you should be fine...Unfortunately low powered GPO's cannot handle any of these functions unless modified.

thanks miles!

so three inverters on the high powered gpos

how easily can the low powered gpos be modified to handle 12v 0.6A? Can you point me in the direction of a tutorial?
