Electrical equipment that operates below its voltage rating can overheat or power down. Here's how to determine your load's operating voltage. Voltage drop across switchgear and feeder and branch ...

Voltage Drop Calc gives line workers a tool to determine the proper wire size for an electrical circuit, based on the voltage drop and current carrying capacity of an electrical circuit. Available ...

Frederik Dostal explains the rise of the ideal diode and how it can be used to develop more robust power systems.

With the holiday season in full swing, lights and decorations are appearing on homes and businesses across Chicagoland. But ...

This circuit is a Mosfet-based linear voltage regulator with a voltage drop of as low as 60mV at 1A. The circuit uses a 15V-0-15V transformer and employs an IRF540 N-channel Mosfet (Q1) to deliver the ...

Environmental systems that precipitate dust and carbon particles frequently use high-voltage dc power supplies. However, failure of high-voltage components caused by a change in their properties over ...

When clients call you because operating problems on pieces of their 120V equipment cause them to suspect their facility's power supply, you have to decide where to start your investigation. Don't ...

There are many circuits for low voltage regulators. For higher voltages, such as supplies for valve circuits, the situation is different. That’s why we decided to design this simple regulator that can ...

Achieve max electric fuel pump output and safety using a relay plus an oil pressure safety switch. Achieving maximum output and safety with a custom-wired electric fuel pump requires a properly ...
