The heat sink is specially designed for single-phase SSR solid state relay, made of high quality and durable aluminium material, strong and corrosion-resistant, so that the product has good heat dissipation, fast cooling and long service life.
The mounting is stable and not easy to fall off, which can better protect the relay. Note that thermal conductive silicone grease needs to be evenly applied between the solid state relay and the heat sink.
It is an important part of temperature controllers and other mechanical control systems for solid state relays.
