1.When choosing a SSR,please pay more attention to actual load current and ambient temperature. When the SSR is used for full load operation, we'd better install an adequate heatsink or take other effective cooling measures. When the ambient temperature is high, the load current must be reduced. Please refer to the curve of "Max. Load Current vs Ambient Temperature".
2.Apply heat-conducting silicon grease or a thermal transfer pad on the space between SSR and heat sink. Then, screw the heatsink firmly. In that case, it would keep the SSR from damaging by overheat.
3.It's recommended to use the matched heatsink by Jinxinrong. If the user needs to use home-made heatsink, it's needed to ensure that the SSR base temperature does not exceed 85
4.Tighten the module screw terminals properly. If the screws are loose, the module would be damaged by heat generated from connection. Also excessive screw mounting torque may damage module internal components. Recommended screw mounting torque as follows: M4 screw mounting torque of (0.98~1.37)N.m, M3 screw mounting torque of (0.58~0.98)N.m.
5.Please do not use the relay beyond the descriptions in the data sheet.
