International Rectifier, a provider of power management technology, introduces a quartet of devices in a new line of RAD-Hard solid state relays (SSRs) for high reliability (hi-rel) applications. The ...

Since the mid-1980s, semiconductor technology has promised to provide smart power products for solid-state relays that could carry high current and provide unique functions for customers. However, ...

Most of Europe’s 240 million electricity meters are expected to be replaced by smart meters by 2020. It is currently estimated that approximately 78 million of these meters will need to use AC ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the power dissipation in a ...
