Designers often use relays as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. However, the power dissipation in a relay ...

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 ...

Pickering’s smallest miniature SIP reed relay with a power rating up to 80 Watts offers alternative to mercury wetted reed relays or electromechanical relays Leading manufacturer of high performance ...

Omron has announced mosfet opto-relays that can switch 3.3Aac or 6.6Adc, giving them the highest-ever current carrying capacity, said the firm. Mosfet relays use light to isolate the primary side, ...

Not long after I began contributing to Hagerty eight years ago, I wrote a detailed four-part piece on electrical relays and how they work in cars. You can still find the articles here (Part I: Why We ...

The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

A May 2014 fire knocked out the Martin Drake Power Plant of Colorado Springs Utilities (CSU). The fire damaged all three coal-fired units, quickly disabling the entire 254 MW facility. The plant ...
