When cheap SSRs cost you more: technical and safety failures explained Choosing low-cost, poor-quality SSRs might seem like a way to save money, but it can lead to serious consequences. These products often feature hidden compromises—lower-rated components, flawed designs, and inadequate testing or certification—that put both your equipment and personnel at risk. Key dangers of […]
AC SSRs : difference about switching thyristor and triac AC switching solid state relays use back-to-back Thyristors and TRIAC’s as their built-in output switching device. What is the difference between Triacs and Thyristors ? Working principles of Thyristors and Triacs Most common output devices used in AC SSR are silicon-controlled rectifiers (SCRs) and triacs, both are part […]
3-phase Solid State Relays and Contactors A three phase Solid State Relays (SSR) is 3 individual single phase SSRs packaged in a single housing with a common input so that each SSR is energized simultaneously. In fact, it is not unusual to use 3 individual SSRs to switch a three-phase load but this is of […]
DC Solid State Relays In a DC Solid-State Relay (DC SSR), various semiconductor technologies are used for switching the DC load. The main technologies typically used in DC SSRs are MOSFETs, IGBTs (Insulated Gate Bipolar Transistors), and Bipolar Junction Transistors (BJTs). Each of these technologies has its own strengths and trade-offs, and they are suited […]
7 reasons to use solid state relays A solid state relay is ideal when fast, frequent switching is required. Throughout this article, we will give you the key advantages of using a solid state relay. 1- SSRs have an infinite lifespan for a long service life SSRs do not have any moving mechanical parts so they […]
