      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.
