2020-03-09 Newer power supply not yet delivering what I want 1 year ago
I did some more testing with the HP power supply I bought last November. In previous tests the output voltage seemed to be limited at 13 volts and it seems limited to 13.10 volt at the moment. The RM Italy HLA300V plus amplifier I have will only output about 55 watts maximum in digital modes so that's less than I expect. A higher input voltage may fix this, but I'm not sure how to get the power supply to deliver this and keep running. The previous power supply gave up in a busy weekend but before that the HF linear amplifier delivered more power. I have seen it go over a 100 watt on digital modes. The difference in output from the linear amplifier with 13.10 or 13.27 volt power is quite large, which surprises me.
