Tenma 72-7570 Schematic
« on: June 28, 2023, 02:17:13 pm »
Anybody have any source to the schematics for this power supply? something is a miss with my right channel ( left channel works ) .

My Google Foo is failing me.


( looks like a Dual Version of a Aim-TTi CPX400SP )

OK, Found this link here:

https://www.eevblog.com/forum/repair/sorensen-xpf-60-20dp/

Going to confirm its the same unit and post here, if same unit, i will update that post and delete this post

The power supplies are pretty much the same, the Tenma has a different front, not programmable, no RS232/Remote Power/GPIB interface.

The Left / Right Power Supply modules have silk screens of CPX400 PCB , the front has CPX400A CONTROL
