STEP 1: Choose a correct type for current
For Resistive load: Current of SSR =2 x working current of load
For Inductive load:Current of SSR =6 x working current of load
For Capacitive load: Current of SSR =10 x working current of load
STEP 2: Choose a suitable heat sink.
When SSR working, it will give out a lot of heat, so in order to extend the life of your SSR, please install a heat sink , also if the current is over 60A,the cooling fan also required.
And don't forget apply heat-conductive silicon greasebetween SSR and heat sink.
Attention: 1. Use fast fuse to protect SSR from load short circuit.
2. The temperature of heatsink atuse must below 80°C.
3. It is better to use varistor for inductive load..
Product details
Solid state relays is a kind of electronic switch that without mechanical contacts, adopting photoelectric device and transformer to
electric isolate or signal couple the control circuit (input circuit) and load circuit (output circuit), drive solid power device to make and break or switch the load circuit. Although there are various solid state relays of different specifications in the market, their working principle is similar, and mainly made up of input (control) circuit, drive circuit and output (load) circuit.
The input circuit of solid state relays is used to input control signal and work as the triggering signal source. Generally, the input
circuit of solid state relays is DC input (like resistant input, the input current will have a linear variation when voltage changes), but some are AC input.
