Suited for metering applications requiring 0.2% accuracy, PA3207NL Sidewinder® is linear from 0.1–200 A and fits standard 0.750 x 0.093 in. buss bar of ANSI 2S smart meter. Sensor provides accurate measurement of AC current at 50 or 60 Hz and also meets ANSI C12.20 standard for immunity to external magnetic fields. While primarily designed for smart meter applications, unit can be used in industrial motor controls, power line monitoring, and commercial and industrial circuit panels.

Current Sensing Resistors range from 0.25-500 ohms.

2013-07-16 14:31:13| Industrial Newsroom - All News for Today

Designed to provide optimal performance when mounted on chassis or cooled heat sink, Models VHP4Z and VPR247Z offer power ratings of 10 W (heat sink) and 3 W (free air), and 4-terminal Kelvin configuration for accuracy in high-power applications. Hermetically sealed units feature low TCR of ±0.2 ppm/°C, PCR of 4 ppm/W typical, and tolerances to ±0.01%. Offering welded construction and screw-mount for attachment to heat sink, VHP4Z has copper leads, while VPR247Z features gold-plated copper leads.
