    Tips: Zero-crossing Solid State Relay vs Random Turn-on Solid State Relay

    When a valid control signal is applied at the input, the random solid state relay output is immediately on (in microseconds) and the zero-crossing solid state relay is turned on until the load voltage crosses zero (± 15V). When the control signal is undone at the input, the zero-crossing and random SSRs are turned off at the time when their holding current fails.

    Although they are likely to cause a maximum half-cycle delay, zero-crossing solid state relays reduce the impact on the load and RF interference, which makes them ideal switching devices that are most commonly used in "single-pole single-throw" switching applications.

    Random solid state relay is characterized by fast response. It can control the phase-shift trigger pulse to easily change the AC grid voltage, and therefore, it can be used to accurately adjust temperature, dimming and other resistive loads and some inductive loads occasions.

    Solid state relay (SSR) is simple but widely used in the automation fields. Thus, it is not complex to wire a solid state relay. In this vedio, ATO takes a 40 Amp SSR (DC - AC) for example to show the wiring of a SSR and then switch on/off a motor with this SSR.
