SSR Heat sinks categories

Lorentzzi provides many kinds of SSR heat radiators for different solid state relays. From product dimension aspect, they can be classified as small radiators such as I-50 and W-70 heatsinks, large heat sinks including Y-110 and H-150. If from installation aspect, they can be  din rail heatsink like D-74 and panel mouting heatsink as I-50, and so on. We can cut these radiators length according to your requirements.

Frequently asked quesions

During the working process of the solid state relay, the solid state relay will generate a lot of heat. If the heat is not dissipated in time, it will cause damage to the solid state relay. In addition, because the operating temperature range of the solid state relay is -20-80 degrees Celsius, too high a temperature will cause the output current to decrease, resulting in insufficient output power.

If the solid state relay output current is not more than 10 amps, no need to use it with heatsink. Once above 10A, you should choose a suitable heatsink. You can contact with us to get more suggesions to choose a suitable heat radiator.

Yes, there are two colours available for the heatsinks. One is silver colour without any surface treatment, this one is much cheaper. The other is using anodizing treatment to make it black colour, its price will be higher but have better corrosion performance resistance.
