    Tips: What are the differences in the use of zero-crossing SSR and random turn-on SSR?

    The zero-crossing SSR is used as a switch on/off. In terms of the switch function, it is equivalent to an ordinary relay or contactor. The solid state relays we usually talk about are mostly zero-crossing type (zero-crossing SSRs can only be used as an on-off switch, not for voltage regulation).
    Random turn-on SSRs are mainly used for chopper control. But the control signal of the random turn-on SSRs must be synchronized with the grid and rise with square signals ranging of 0º-180º to realize voltage regulation which, however, fails under the circumstance of a single voltage signal or 0-5V analog signal. From the voltage regulation function point of view, random turn-on SSRs are completely different from ordinary relays or contactors. It must be emphasized that devices used in the all kinds of voltage regulator module or solid state relays as an output contactor are SCRs, and achieve the purpose of voltage regulation relying on changing the operating angle of SCRs. Therefore, the output voltage waveforms are sine waves with unfilled corners (different from the full sine wave from the autotransformer output), and accordingly, there are higher harmonics and certain noises, and the grid has some pollution.
