An overload or short circuit in a fuse or mini circuit breaker can lead to undersupply or failure of an entire 24-V dc power-supply system. Selectivity protection using an electronic fuse offers a ...

If you’ve got the hankering to own a lab full of high-end gear but your budget is groaning in protest, rolling your own test equipment can be a great option. Not everything the complete shop needs is ...

Connecting a DC power supply to a load appears to be a simple, straightforward task. In other situations, it can be a challenge. This white paper will describe various types of loads that can be ...

Because stationary batteries and 48VDC power systems serve as lifelines for telecommunication networks, the reliability of these systems is of the utmost importance. Many system designers rely on ...

This is probably fairly straightforward for an EE to weigh in on so I thought I’d post this question here for posterity in the hopes that it’ll solve the issue for other designers. The challenge is ...

You use an active-load test circuit to ensure that a power supply for a microprocessor or for other digital loads supplies 100A transient currents. This active load can provide a dc load for a power ...

Suppose you have a 60A breaker supplying a branch circuit. What size conductors do you need for that circuit? One table in the NEC says No. 8; another says No. 4. Which one is right? What does the ...

Semiconductor memory, card readers, microprocessors, disk drives, piezoelectric devices, and digital systems create transient loads that voltage regulators must service. Ideally, regulator output ...
