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” ...

Each motor branch circuit must be protected against short circuit and ground faults by an overcurrent device sized no greater than the percentages listed in Table 430.52. A branch-circuit ...

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 ...

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 ...

Testing a circuit breaker is about judging reliability under fault conditions, not just checking continuity or voltage. A ...

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.

Circuit breakers now sport advanced features that include remote control and operational status reporting. Engineers have long considered circuit protection a stable if somewhat unglamorous area.

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...
