A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

In various industries and applications, it’s crucial to monitor the current and frequency of devices in real-time. These ...

Automotive, industrial, and FireWire peripherals all call for high-efficiency, space-saving power supplies with high current capabilities at very high voltages. The problem is that high-voltage, ...

The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers and an Arduino compatible ATmega328p microcontroller. Sense resistors are used to measure how ...

The ability to turn on loads in a controlled manner is important in applications where the power budget is limited. Hard switching a load can cause the input power rail to droop and result in a fault.

A 480V, 3-phase, squirrel-cage motor is a common piece of equipment in many facilities. When sizing circuit breakers, fuses, and conductors for a general AC motor branch circuit, National Electrical ...

Diodes Incorporated has announced the introduction of the AP22913, a 2A single-channel, slew-rate-controlled load switch with true reverse current blocking for high-side load-switching applications.

This constant resistance dummy load has not yet been tested in the real world. [YS] was inspired to come up with the circuit after reading Wednesday’s Re:load dummy load post. That was a constant ...

For modern distribution protection, Negative Phase Sequence (NPS) Protection is often relegated in favor of common elements such as Overcurrent (OC) or Earth Fault (EF), but NPS is an incredibly ...
