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 ...

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” ...

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 ...

The A_S-1WR and B_LS-1WR series of 1-W SIP dc/dc converters feature continuous short circuit protection and are enclosed in a 0.77 x 0.37 x 0.24-in. package. They feature a continuous output short ...

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.

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 ...

Note: This article is based on the 2011 NEC. Article 430 provides the requirements for electric motors while Art. 440 offers amended and additional requirements for hermetic motors, such as those used ...
