Operating from a 24-Vdc isolated power supply, the devices use an input control from 4 to 20 mA or 0 to 10 Vdc. Features of the relays include an integral heat sink for controlled cooling, DIN-rail ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

This file type includes high resolution graphics and schematics when applicable. According to the research firm IHS Inc., about 54 million relays and timers were purchased in 2013, a number projected ...

Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal operating conditions that overload devices and breakers cannot see, guiding ...

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 ...

This 6V solar charge regulator meets most small-scale 6V application requirements. With a current rating of 6A, it can handle up to a 50W solar panel. Its principle of operation is very simple and ...

Many varieties of ON/OFF control circuits use some form of flip-flop that responds to a pushbutton switch or other control input. These all have volatile memory and default to an OFF condition if ...
