Solid-state relays provide robust solutions for electronic switching in load control applications and hold many advantages over electromechanical relays. New, emerging solid-state relay designs offer ...

Mitsubishi Electric recently visited EnergyVille, a collaboration between the Flemish research partners KU Leuven, VITO, imec and UHasselt, to install a prototype of its HVDC line protection relay ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding interconnections, and increasing dependence on distributed energy ...

To be competitive, some electrical contractors often supply low-voltage (LV) service entrance switchboards and switchgear that meet the minimum safety requirements of the National Electrical Code (NEC ...

ABB's Coral Springs, Florida, facility has begun the production of the Relion 615 series ANSI-based distribution protection relays. This is a major milestone not only for ABB in North America but also ...

Hawthorne, Calif. — A new series of LSD PCB-mount, DC solid-state relays from Teledyne Relays combines a thin, compact design for board space savings and a thermally conductive metal base for heat ...

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 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 ...
