Note:
1.The zero cross function turns ON the SSR when the AC load voltage is 0 V or close to 0 V. SSRs with the zero cross function are effective in the following ways.
・ Clicking noise when a load is turned ON is reduced.
・ Effects on the power supply are reduced by suppressing inrush current with loads, such as lamps, heaters, and motors, thereby reducing inrush current protection circuits.
2. For 200-V models, use a triac on the output switching elements.
