Note 1: The unit of temperature in the table is ℃
Note 2: When tested room temperature is 28 ℃
8.4 Expansion experiment
In order to prove that improve the level of heat sink will improve the SSR limit operating current, I did an
expansion experiment.
Since I had not a larger heat sink on hand, so I installed a fan (which I take for my PC’s CPU) above the
SSR. As shown in Figure 3.
I just test the stable time of different operating current, as shown in Table 2.
