I recently discovered in my collection of interesting things that I had a Kerio Energy Knight I. When plugged into the 12V car socket the output was measured at 24V. There is an orange two pin device that when removed looks like a fuse. On inspecting the data sheet found above I discover that it is called an output voltage adjustment device {ovad} . Until now I thought it was broken somehow. I do not have to my knowledge any alternative ovad but I now know that I have a way of getting 24V from my car...
