The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

ABB has launched its latest generation Fiber Optic Current Sensor (FOCS-FS) to complement its portfolio of optical sensors. The FOCS-FS gets its name from its ‘free standing’ design. A salient feature ...

The ACS722 and ACS723 Hall-effect current sensor ICs from Allegro MicroSystems Europe are being offered in a new high-isolation SOIC16 package. It is a low-profile surface-mount package which provides ...

LEM has announced three-phase current sensors that fit silicon carbide power modules typically used in 800V vehicle traction inverters. “Developers of automotive traction inverters are increasingly ...
