Choose the right radiator
Choosing the right heatsink canmake your product last longer
Step 1: Choose a control method
Step 2: Calculate the current
Equipment current + factor = selection current
Selection current X coefficient= equipment current
(Coefficient: resistive load is 3-3.5 times, inductive load is 5-7 times)
Resistive loads:electric heating, incandescent lamps,….etc.Inductive loads are:motors, transformers, capacitors, solenoid valves,air conditioners, lighting with inductance
Step 3: Choose the right radiator
The solid state relay generates a lot of heat. When the loadcurrent is higher than 10A, a heat sink must be used.Thermal grease must be applied between the solid staterelay base plate and the heat sink.(Above 40A plus fan cooling)
