TAB V372-1D racking power supply issue.
Posted: Sat Sep 15, 2012 1:11 am
Hello everybody.
I'm currently racking up a TAB V372-1D card as a dual channel mic preamp.
Finished the basic part and everything worked fine except for the 2 Vu Meters (JLM Large VU meter) because I didn't have a 12V rail to power them.
So the idea was to get an other TREX2 kit (I already use one to obtain the 24V rail to power the amp card and for the 48V phantom power) and to use it to get a 12V rail to power the VU meters. Problem is when doing this, my main power supply ( 48v 25w 520mA SMPS) turns off probably because there is a protection inside to prevent damage.
My question is the following: Is it a power issue ? Is the 25W power supply not enough to handle the two TREX2 and I should get the 40W version or is the problem somewhere else?
Thank you.
Ben
