 +To use a Lenove Power supply together with my traveling solder station T12-642 I build a small TRIM adapter. The Lenovo power connector is called "TRIM Series connector" and my solder station needs a 5.5mm round jack power connector. So I needed a TRIM to 5.5 jack plug.\\

 +To adjust the power of the supply one has to put a resistor between the signal pin and ground. Because I need 100W I used a 1k resistor between the signal pin and the ground.\\
