PWM relays allow engineers to go beyond simple "on-off" control to realize significant power savings and reduced heat ...

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.

This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

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, ...

This new range of AC and DC solid state switching devices is an ideal solution for switching resistive, slightly inductive and motor loads, thanks to the reduced size per unit - starting at only ...

Here’s a MEMS relay with an integrated FET that can handle higher power levels, breaking away from the “low power” moniker associated with MEMS parts. Paul Rako takes a closer look at what makes this ...

Relay selection can significantly impact power consumption, system behavior, and long-term reliability in electronic designs.

Sometimes, the most unexpected detours lead to the most interesting discoveries. After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be ...

Omron has designed a relay that can interrupt 200A at 500V, aiming to displace contactors from dc electric vehicle chargers, batteries and solar inverters. “A proprietary gas-less design cools arcs ...

Meeting the requirements of MIL-PRF-83536 specification and ISO-9001 certification, this new series of power relays has been specifically engineered for mission-critical commercial aviation, defence ...

An electrical relay is a type of heavy-duty, remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. Relays install between the ...
