Feature: *Strictly prevent current breakdown: The breakdown voltage of the optocoupler determines the safety of the solid-state relay * Silent and low-noise, no risk of sparks: Solid-state relays use internal working methods, no mechanical contact Actions, no contacts, so no sparks *High-quality flame-retardant shell: good insulation performance, safe and lasting, the circuit design is protected by double triodes, and the control terminal is more stable *High-quality terminals: Welded and installed with copper pillars, the wiring is stable and not easy to fall off. The terminal board is made of copper, with good conductivity and corrosion resistance. *High-quality aluminum base plate: The aluminum base plate and the thyristor/chip (insulation package) are closely adhered to each other to transfer large amounts of heat instantly, creating strong heat dissipation performance.
