    Tips: AC solid state relays vs DC solid state relays

    Depending on the type of load power supply, SSRs can be divided into AC Solid State Relays (AC-SSRs) and DC Solid State Relays (DC-SSRs). AC-SSRs use a bidirectional thyristor as a switching device to turn on or off the AC load power supply. According to the type of control trigger, AC-SSR can be divided into zero-crossing and random turn-on. Zero-crossing AC-SSRs switch on when AC power supply goes through approx. zero voltage after control signals input. Therefore, their interference is small. The random turn-on AC-SSRs switch on or off in any phase of the AC power supply, so there may be more interference the moment they turn on.
    Compared with AC-SSR, DC-SSR has no zero-crossing control circuit and does not need to install a absorption circuit, and its switching devices generally use high-power switching transistor, except which, they have the same working principles. When DC-SSR is used, it should be noted that:

    1. In the case of inductive load, such as DC solenoid valves or electromagnets, a diode should be set in parallel at both ends of the load. Meanwhile, its current should be equal to the operating current, and its voltage should be 4 times greater than the operating voltage.
    2. During its operation, try to put SSR close to the load, and its output lead should meet the needs of the load current.
    3. Its filtering electrolytic capacitor should be large enough when the used power supply is obtained by AC brownout rectification.
