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 ...

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 ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

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 ...

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, ...

Sensata Technologies announced the availability of two new three-phase DIN rail- and panel-mount solid-state relays (SSRs), the DR67 and PM67 series, for use in a variety of industrial power ...

Pickering to include a new variant with an electrostatic shield between the switch and the coil to help minimise noise.

Cooper Power Systems delivers increased protection and control and communication capability through seven different capacitor bank protection relays. The Idea Workbench easily functions by ...

Getting power to anything from lighting to video walls should not be an afterthought. Today’s digital endpoints have added new challenges, putting a spotlight on the need for proper power control and ...

This 12V solar charge regulator meets most small-scale application requirements. With a current rating of 6A, it can handle up to a 100W solar panel. Its principle of operation is very simple and ...
