Three-phase solid state relay Random trigger, DCto AC control  
   
1. It replaces the shortcomings of heat dissipation, current resistance and voltage withstand voltage of single-phase SSR, and is inconvenient in assembly.

2. Built-in over-temperature protection system (included above 55A), the heat sink temperature is above 95°C, and it is automatically returned below 70°C.

3. Applied to load: IR tube, quartz tube, heater.

4. Small size and high capacity, the fuselage and heat dissipation are integrally formed, and the heat dissipation is optimal.
