XFR12

• Buy XFR12

I tested the XFR12 that I use as part of my bench test setup since I had everything set to go anyhow. I use it to power whatever booster I am using during a test.

The results are shown in the graph below. I have also included the source Excel spreadsheet so you can look at the data directly. The line voltage was wandering around a bit while I did the test, which is why the XFR12 seems to drop done a bit. The open circuit voltages are probably worst case at a line voltage of 122 volts.

The open circuit voltage of the XFR12 was 19.46. This is in excess of the maximum 19.2 volts specified for the PH1, but is well within the 22 volts specified for the PB110A ten-amp booster. Although I have been using it with the PH1 with no problem, the XFR12 should probably only be used with the PB110A or other high current boosters.
