AC current sensor fits existing solid conductors
Capable of being clamped onto an existing solid conductor without having to disconnect it, the PA3828NL 50/60Hz, di/dt AC current sensor has been unveiled by Pulse Electronics. The clamp-on sensor is suitable for applications include metering, industrial motor control, power monitoring, circuit protection and current fault monitoring.
For high precision power measuring applications at 50/60Hz AC, the sensor features a linear current range of 0.1-200A with 1.0% accuracy. The PA3828NL has an internal diameter of 6.2mm which opens to 7.0mm to clamp onto a conductor. This clamp feature can be opened and closed multiple times.
The clamp-on current sensors are RoHS compliant and meet ANSI C12.20 accuracy Class 1.0 standards. They are core-less, not containing a magnetic core, which makes them more accurate, highly linear, lighter, easier to assemble, less expensive and more flexible.
Glenn Roemer, Field Applications Engineer, Pulse Electronics, comments: "Pulse's new current sensor is quite unique. 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 PA3828NL clamp-on current sensors are sold in trays priced around $1.75 (USD) in 10,000 unit quantities. Leadtime is 8-10 weeks.
