When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s). It utilizes a current transformer, single ...

Solid-state relays are much smaller than corresponding single-pole relays. They are also faster, dissipate less power, and withstand a larger number of operations. And unlike electromechanical relays, ...

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system. Introduction to AC and DC Power ...

Switching ac power on and off has been a challenge since Edison and others started switching power more than 125 years ago. Now, a solid-state relay (SSR) uses a patented zero-voltage crossing ...

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

With a few mouse clicks you can easily purchase Solid State Relays (SSRs) online. Or you can make one at home with a handful of different electronic parts. The question is– should I buy it or make it ...
