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.
