In another thread I mentioned I'm building a AC/DC power supply for my laptop (see here:
https://www.eevblog.com/forum/projects/a-46win3-power-adapter-with-active-pfc/).
Since I don't want myself killed, I think I should be able to test my finished product with an insulation meter.
According to UL60950-1, for world wide input voltage (I mostly live in the US, but I go to China every year to visit my family), it needs to withstand 2.5kV peak transient.
The transformer I used is designed for telecommunication system and is only certified at 1.5kV RMS isolation (2.1kV peak), therefore I need to test it myself to see if it will withstand 2.5kV.
Is there a good insulation meter that can do 2.5kv testing? So far I know Uni-T has some cheap ones, particularly UT533 and UT502A. I'm not interested in the much more expensive UT513A. My budget is $300 or less.
I don't need high accuracy -- just a qualitative test. For precision works, I have a Keysight U1461A and a Keithley 2410 SMU, but both only go to 1.1kV, even series connect them together it is still not enough to generate 2.5kV test voltage.
Any recommendations? Thanks in advance.
Bought UT502A.
