Thank you so much for this thorough review! I was just to buy a power supply but ordering online can be like buying a pig in a poke, this solves my problem!
VERY GOOD REVIEW KERRY.
Another excellent review. You measure the important stuff.
I like that you keep the UT61e+ around. I always appreciate the speed and accuracy of mine.
electrophoresis supplies are nice for hv experiments, they can go to 3kV. good for tube amp projects but need to be loaded by a few meg resistor to even turn on and immediately shut off when theres a abnormality like current going to ground.
So, how can you reduce the noise/ripple ?
I would like you to test the power supply with a full short circuit on the output at full current and increasing voltage.
Will it survive?
You should dig out the electronic load you built, which had a larger power capacity.
I am planning to purchase this to test flyback converters, which later-on, will be run on mains.
What is your purpose of purchasing this HV power supply?
Definitely would be nice to have the 160v isolated so you can inject it into a psu cap. Also 160ish is the peak output of 120v mains.
Is this supply limited to 2A across all voltages or will it allow more current at lower voltages to achieve the 300W output?
To give it a better test to find its real current and voltage wave form you need a resistive load, not a digital electronic load.
Eevblog also found out this the hard way where both instruments where fighting each other making a horrible ripple, but when eliminating the electronic load it was MUCH better
I was debating that. In my last OWON PS test I used a pure resistive load, but I didn't have anything suitable for the voltage range I was testing with this power supply.
@@KerryWongBlog Try some incandescent light bulbs?
@@KerryWongBlog space heater, any ac heater that is resistive works just the same at DC 😉
I like the video but that PS sucks . horrible lack of filtering
Seems that the power supply is almost useless for electronics usage.
Maybe it's usable for electro-mechanical work.
I hoped that it would have a linear final stage to clean the switching noise.
I’m just looking for a higher voltage when anodizing titanium, so this should work fine. I particularly like the ability to recall memory and change the output digitally without trying to adjust finicky potentiometers.
Resistiv load!!!! Electric load fals....output on...(load on)...OHM load!!!
