درجة حرارة TC لـ power supply is -- the surface temperature of the power supply at the position directly above the transformer when the power supply rises to a stable state.

The transformer is the most prone part of the power supply. To measure the temperature of the TC point, it is necessary to know how much the temperature reaches when the power supply is stable. The TC point is above the transformer, and the product labelon led driver is difficult to put in a very accurate position, so there will be some deviations. Need to point the TC point according to the position of the transformer inside.
