-Signal Pin +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.\\
-  power rating resistance +
-  36 W 7,3 kΩ +
-  45 W 120 Ω +
-  65 W 280 Ω +
-  90 W 550 Ω +
-  135 W  1 kΩ +
-  170 W  1.9 kΩ +
-  230 W  4.6 kΩ +

 +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.\\
