Bench Power: Help a rebel out
« on: March 27, 2019, 10:00:53 PM »
I went about 5 years with the same inexpensive MPJA bench power supply, but it died on me last November so I upgraded slightly to a digital by the same manufacturer. That one died on me after about a month while I was putting 5v into the simplest CMOS oscillator you can make, so they sent me a replacement.  I’ve had it about three weeks now and tonight, while powering a RobotDyn ch34 mega clone which was rated for 9-12 on the Vin, it let the smoke out of the USB chip and stopped reading any current draw.

You all know I’m not new to this but it seems like ever since I turned my iron towards musical instruments I’ve been on a path of destruction.  Can anyone give me some pointers about variable V/I bench supplies, or Did I really get 2 lemons?  (The old one was V only.)
