Notes while using
- Different margins should be maintained for the current rating depending on the nature of the load. (For resistive loads, the selection can be made at 2-3 times the load current. For inductive or capacitive loads, it can be selected at 3-4 times the load current).
- The actual load current is greatly related to the ambient temperature. When the ambient temperature is high or the heat dissipation conditions are poor, the current capacity should be increased. To prevent load short-circuit during use, overload protection should be added in the load circuit or a GH19L overload current protection type solid-state relay should be used.
- To prevent harm from high-order harmonics of the power supply, an overvoltage protector should be connected in parallel at the output end to prevent damage to the solid-state switch in case of overvoltage. Selection of Metal Oxide Varistor (MOV): choose 430-470V for the 240V range, and 680-750V for the 440V range.
- The contact surface between the matching heat sink and this product must be flat and smooth, and a layer of thermal conductive silicone grease should be applied to its surface. When fixing, screws should be tightened symmetrically with spring washers and flat washers to prevent loosening due to thermal expansion and contraction.
