It’s hard to say anything at this point. The plan was to have something in the next year, but due to the lack of a very large number of components,...
Today is possible to make high quality and precisely drilled PCB with any silkmask in many different colors (incl. blue and black). Therefore module's front panels can be made as...
This issue require firmware change as reported in [#177](https://github.com/eez-open/modular-psu-firmware/issues/177) and removing of Q27 in r2B11 version or Q10 in r3B3 version of the DCP module. That MOSFET was added against...
Ramp is needed on both power up and OE on if set current is below 170 mA, but it seems that is not so simple. With higher Uset bigger Iset...
I can't test 115 Vac and 60 Hz here, I only have 50 Hz, but it seems that the situation is even more alarming. Fortunately, capacitors help in this case...
What will happen if R4 burns out? Soon after the power up DCP and DCM modules will report an error as they will get DC at their inputs only for...
The capacitor used is 4u7, X2 Kemet [R46KR447050P1M](https://hr.mouser.com/ProductDetail/80-R46KR447040P1M). A bleeder resistor can be connected in parallel (470K to 1Meg): 
It seems that only one capacitor is needed, even if three Mean well's are used: 
@gregdavill this is really strange since @goran-mahovlic reported that only single 0.47uF rectify this problem for him. I tested it on my side with 4.7uF as already reported. I still...
I tried right now two new Mean Well randomly selected from piles and another AUX-PS "green" version. Not the slightest change in temperature can be measured on R4. See pictures...
