Last month we examined the operation and application of the potential starting relay. This month we will cover voltage specifications of the potential relay. Compressors may have one of three voltage ...

AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a ...

Description: This product provides direct line-voltage control without the use of low-voltage pilot relays. The compact, multichannel line-voltage relay solution communicates on any Reliable Controls ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

What's a designer to do when challenged with a switching application that requires handling up to 70 kV? These applications are not as rare as one may think. In fact, a broad range of applications in ...

The circuit was designed to provide a voltage over and under the specified value with the use of a switch that will be operated by a relay. LM741 – a general purpose single operational amplifier with ...

In this QuickChat, James Morra, senior editor at Electronic Design, sits down with Robert King, product development manager at Pickering Electronics, to explore the evolving role of high-voltage ...

The circuit shown in the figure uses stored energy in the multiplexer relay coil to boost the power-supply voltage from 3.3 to 5.1 V. This extra voltage enhances the amplifier's ability to produce a ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess ...

Automotive components that have a hidden secondary function are usually limited to cartoons and Michael Bay movies, but this project that [Jesus Echavarria] created for a client is a perhaps as close ...
