RECOMMENDED MODEL & HEATSINK
Choosing compatible current is critical in selecting a right model of solid state relay. Our engineers recommend SSR models according to actual applications and internal components of relay. For example, when solid state relay is used for electric heating, because of the cold resistance effect (the resistance value is 60% of heating wire value when it is in cold state), the SSR’s current should be 1.67 times bigger than actual working current in order to prevent the over-current of solid state relay.
