Featuring DC to 5-MHz bandwidth, Allegro MicroSystems' galvanically isolated, high-accuracy magnetic current-sensor IC with zero current reference (ACS37030), and overcurrent fault with internal pull ...

The Allegro ACS713 provides economical and precise solutions for DC current sensing in industrial, commercial, and communications systems. The device package allows for easy implementation by the ...

To sense high dc currents, designers typically use shunt resistors or Hall-Effect-based current sensors. But shunt resistors are plagued by Joule (I2R) losses and the need to open the circuit where ...

I got a couple of INA 219 modules from an online seller overseas. I was looking for a different dc current sensor module to start a small battery charger project, so I welcomed them. The INA219 based ...

Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.

Isolation in this case, is from the mains, and it transpires that finding something that will do the job safely is tricky. Three isolated Hall-based current sensing modules are easy to obtain, as far ...

Allegro is claiming isolation up to 1.3kV dc (650V reinforced) for a series of current sensors that work up 400A (ac and dc) and respond in 2.5µs for fast over-current detection. Safety-critical ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...
