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 ...

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, ...

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

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

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 ...

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 ...

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 ...
