Any time you are working with burglar alarm, access control, sound, nurse call, or intercom systems, as well as computer networks, lighting dimmer controls, and low-voltage industrial controls, you ...

In this exciting video, we dive into the world of controlling high voltage DC motors and the intricate process of designing a ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Short circuit current ratings should not be overlooked during panel design. Negative impacts can occur to production, equipment and, worst case, plant personnel. Per 2014 NEC Article 100, short ...

The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE NO contacts ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

Faced with ever-increasing cost pressures and demands for improved performance, machine builders are actively seeking new automation solutions with improved cost/performance ratios. In response to ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

One of two uninterruptible power supply (UPS) systems had become “interrupted,” and no one onsite knew where the bypass ...

One simulates up to 50× faster than the other, and both will give you comparable accuracy. Which engine would you choose for your power supply circuit? Sounds like a trick question, but it isn’t.
