Pulse Electronics Corp. has unveiled a 50 Hz/60 Hz, 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 50 Hz/60 Hz AC. Applications include metering, industrial motor control, power monitoring, circuit protection, and current fault monitoring.
The sensor has an internal diameter of 6.2 mm and opens to 7.0 mm 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.
The current sensor is RoHS compliant and meets ANSI C12.20 accuracy Class 1.0 standards. It is sold in trays with prices around $1.75 in quantities of 10,000. Leadtime is 8 to 10 weeks.
