With 51.1 VDC on input of the regulator, the unit powered on 3 separate times successfully without incident, however, on 4th attempt it quit!

No display. Any thoughts?

•  Yes, that’s exactly the model in question; NC 900 watts Regulator # 200150

Again, 51 VDC into the input with no load conditions..turn the regulator on and off a total of 3 times just to check to see if output could be adjust from 80vdc to 63 vdc, but output failed to be adjusted, so the unit was turnt off again, and on the 4th attempt to repower unit failed — no display!

I have since returned unit for a refund. I will purchase same model and try again.

Thanks for your reponse.
