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 is the difference between a Standard Package SSR (TRIAC output) and an Industrial Package SSR (anti-parallel SCR output)?
For resistive AC loads, the difference between the two is small. Standard Package can use up to M5 screws, while Industrial Package can use up to M8 screws.
For inductive or capacitive AC loads, when the solid state relay is turned off in the on state, a large voltage-rise rate dv/dt (commutation dv/dt) will occur due to the inconsistent phase of the current and voltage. Such dv/dt affects the output efficiency of TRIAC, or even damages TRIAC, but the effect of commutation dv/dt on anti-parallel SCR is very small. Therefore, for AC loads with large inductance or capacitance, it is more suitable to choose industrial solid state relays.
