Pulse Electronics Corporation, a leading provider of electronic components, introduces its new 50Hz/60Hz, di/dt AC current sensor that can be clamped onto an existing solid conductor without having to disconnect the conductor.
The PA3828NL clamp-on sensor has a linear current range of 0.1 amps to 200 amps with 1.0% accuracy for high precision power measuring applications at 50Hz/60Hz AC. Another growing application is for arc fault AC current monitoring, sensing frequencies up to 1MHz. This sensor is the latest addition to Pulse Electronics’ Sidewinder® current sensor family. Applications include metering, industrial motor control, power monitoring, circuit protection, and current fault monitoring.
“Pulse’s new current sensor is quite unique,” explained Glenn Roemer, field applications engineer, Pulse Electronics. “It enables the sensor to be installed into an existing application without disconnecting the system, thus providing a lower installation cost for AC current measurement and AC power control applications.”
The sensor has an internal diameter of 6.2mm and opens to 7.0mm to easily clamp onto a conductor. It is core-less, lightweight, and can be quickly installed. The robust clamp feature can be opened and closed multiple times.
The Sidewinder family of current sensors provides a highly linear output voltage over a very wide dynamic range from 0.1 to 1000 amperes. These sensors differ from traditional current sensors because they do not contain a magnetic core. This makes them more accurate, highly linear, lighter, easier to assemble, less expensive, and offers flexibility of design to suit a wide range of applications.
