Re: current-limited power supply.

 

Well, I ordered some of the Current Limited PSU boards from AliExpress and
they have arrived today.
I've tested the silicon with a DVM and they appear to be ok, and everything
appears to be present.
There is no documentation other than the cct.diag. and PCB layout. I've
attached the cct.diag to this post.
Can someone explain how it works to assist in faultfinding should it not do
so.

Ready to start my QMX high band kit build.

The assembly manual recommends using a current-limited power supply for the
first power-up.

What are members using for this. Lowest cost if possible.

Thanks
