Solid state relays (SSRs) have revolutionized the way we control electrical loads. SSRs offer numerous advantages over traditional relays and have become an indispensable component in a variety of applications. This article delves into the world of SSRs, highlighting their importance and widespread use. Table of Contents What is a solid state relay? A solid […]

SSR and SCR are two common actuators used in industrial equipment, especially in temperature control systems. They have 4 BIG differences, as detailed below: Names differences between SSR and SCR SSR stands for Solid State Relay, while SCR stands for Silicon Controlled Rectifier. Different functions of SSR and SCR SSR is an electronic switching device

Solid state relays can be classified as single phase DC AC solid state relays, single phase AC AC solid state relays, three phase DC AC solid state relays, three phase AC AC solid state relays, and DC DC solid state relays.  Different solid state relays have different wiring diagrams.  So now let’s have a look

Purchasing a good quality solid state relay is one thing, but how to test a solid state relay is a same vital matter. Solid state relay is a kind of electronic switch, which has the characteristics of fast response and high reliability, and is widely used in industrial control, automation equipment and other fields. However,

Contents Overview Although there are many models and specifications of solid state relays on the market, the working principles of solid state relays are basically similar. It is mainly composed of three parts: input (control) circuit, drive circuit and output (load) circuit. The working principle of the solid state relay is illustrated below through two
