Meanwell 1500 watt PSU UPDATE!

[AlanR]

Well you guys may have remembered me from back when I brought up the issue of the capacitors used in my power supply and the buss bar to metal frame clearance issue. Well today I have fixed both of these issues. The capXon capacitor values were 25 volt, 47uF; 50 volt, 10uF; and 50 volt, 3.3 uF. All replaced with Rubycon YXJ series except for the 10uF, which is a Nichicon TT series. I also put a single layer of Kapton tape on the surface of the enclosure that is close to the buss bars as you can see here:

I did a 24 hour load test for this 24 volt power supply by using a 0.50 ohm, 1000 watt resistor with a box fan blowing on it. The PSU did not let out any magic smoke and it held voltage at 23.95 volts.

So far I am satisfied with the results and have been using this power supply to characterize DC motors. Glad it works so well!! It also has no overshoot issues upon power up.

Fuhgeddaboudit! 


(I've got the 48V version... Gonna have to "Take it APARRRT!")
