OK, this is what I have:
I simulated a highly conductive electroplating setup by using almost a dead short across the power supply terminals. The resistance was what 3 feet of 14 AWG wire and two banana plugs provided, about 0.02 Ohms. Low value high wattage power resistors were than added in 0.05 Ohm increments until the power supply would start up properly.
HY1503D (3A CC/CV rectifier)
Will not start with less than 0.2 Ohms in series.
HY3020E (20A CC/CV rectifier)
Will not start with less than 0.5 Ohms in series.
For reference, I also did the same tests on a $1200.00 Xantrex XHR100-10. This is a professional 1,000 Watt CC/CV offline switcher.
Starts with the almost dead short as described above.
Also tested was 500W CC/CV switcher of my own design.
Starts with the almost dead short as described above.
I took the cover off the 20A CC/CV rectifier, it is also an offline switcher, but nowhere near as sophisticated as the Xantrex.
Something you should know about off line switching power supplies; the 120 VAC is rectified and applied to the circuit directly, it is not reduced to a lower voltage with a transformer as in linear power supplies. The necessary isolation transformer is further down stream in the circuit. This means there is 204 - 374 VDC present and at more than enough current to kill you instantly. Don't open them up!.
I expect the 3A rectifier is also a switcher. Both of these are much better than I was expecting for the price.
In Gabourie's case; 5.3V @ 9.4A is 0.56 Ohms, and 3.8V @ 10.6A is 0.36 Ohms.
