The PA3207NL Sidewinder is a core-less, light weight, lower cost, AC current sensor for highly accurate metering applications requiring 0.2% accuracy. The current sensor is linear from 0.1 to 200A. It provides accurate measurement of AC current at 50 or 60 Hz and meets the ANSI C12.20 standard for immunity to external magnetic fields. Although primarily designed for smart meter applications, the non-round shape can be used in industrial motor controls, power line monitoring, and in commercial and industrial circuit panels.
"Instead of shaping the bus bar to fit the sensor, Pulse has designed the sensor to fit the bus bar," explained Glenn Roemer, field applications engineer, Pulse Electronics. "This simplifies the meter base design and assembly and provides measurement and control engineers with a lower cost current sensing solution." The sensor costs $2.15 (10,000).
