If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

Process automation projects are most often driven by bottom line results, return on investment and an appropriate value position or justification. More and more, systems are expected to: All of this ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.

I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...
