    It was fault product.
    Output voltage is 32V at 0A, but supply current only 1.6A, output voltage became down to 24V.
    Open the case then I found two resistor (330Ω5W). Another one product(OK product) have three resistor (330Ω5W).
    I put on resistor, but I cannot fix.
    Finally, I found fault soldering, then I resoldering that.
    then I could fix it.
