Precautions and FAQs

● If the load current is 10A, a heat sink must be equipped; if the load current is 40A or more, an air-cooled radiator or a water-cooled radiator must be installed.
● When the load is an inductive load, be sure to connect a varistor in parallel with the output terminal, whose voltage value is 1.6-1.9 times the load voltage.
● What are the differences between Panel mount SSR and PCB mount SSR?
The panel type solid state relay (or device type, screw mounting type) needs to be fixed on a metal base plate or a heat sink, and is cooled by a heat sink or an air-cooled radiator. The PCB solid state relay (or pin mounting type) has the industry standard pin configurations, and can be mounted directly to the Printed Circuit Board, and the natural cooling as heat dissipation without the need for a heat sink. The PCB type has a smaller mounting size and a larger power density than the panel type.
