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.
In this case, since the load is inductive, the current peak value
of the first cycle becomes high due to the transient phenomenon,
and the current peak value becomes low and reaches a steady state
along with the successive progression of the cycle.
The phase of the load current during this process is delayed 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.
