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.Tighten the SSR terminal screws properly. If the screws are loose, the SSR will be damaged by heat generated from connections. Also, excessive screw mounting torque may damage relay internal components. We recommended screw installation torque as follows : M4 screw mounting torque range is (0.98~1.37)N.m, M3 screw mounting torque range is (0.58~0.98)N.m.
4.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.
5.KS34 relay use for inductive load, it is suggested to select random turn-on(i.e., a model with "P" letter) products; KS34 relay use for capacitive load, do not choose products with varistor protection(i.e., a modelwith "Y" letter) .
6.Listed parameters are based on resistive load. Please do not use the relay beyond the descriptions in the datasheet.
