The Linear regulated Power Supply is capable of providing 1..24V at 0..1,5A.
The power supply consists of a LM723-chip with a Darlington-transistor stage as regulator and more current flow. The basics are already explained under “Powoer supplies -> LPS LM723”
Since the FMAS only has one single DC voltage with only 9V, I had to rectify the 24V AC and filtered it. This voltage was then put on the input of the voltage regulator.
With the help of a shunt resistor and a voltage divider the current as well as the voltage could be displayed on a small digital voltmeter. With the flick of a switch you can change between voltage and current measurement. Although the accuracy is not the best (tolerances of ca. 15%) it is enough to see tendencies and errors. You can increase the accuracy by using presicion resistors and a wheatstone bridge. With this it should get way more accurate.
The power supply is one of the biggest modules for the FMAS, so it takes up some space.
