AC SSR Relay AC SSR of Three Phase

Description of AC SSR Relay

When an input voltage is applied near the peak value of the AC power voltage, the current will not flow immediately to the SSR output circuit. When the voltage becomes close to zero due to a drop in the AC power voltage, the triac of the SSR output circuit turns ON, and the current will flow to the load.
The phase of the load current during this process advances up to 90 degrees to the phase of the AC power voltage.
Even when the input voltage is turned OFF, the SSR does not turn OFF immediately. It turns OFF when the load current decreases and reaches below the holding current of the triac.
Note that since this is a capacitive load, the voltage generated by an electric charge stored in the capacitor and the power supply voltage will be added, and a voltage double the peak value of the power supply voltage may be applied to the SSR. Therefore, when using an SSR with a power supply voltage of 110V, SSR for 220V is recommended to be used.
