20 Amp Current Sensor AC/DC can measure up to 20 amps of AC current and between –20 and +20 amps of DC current. It has a dual output design, which allows users to measure the AC and DC components of a complex current waveform separately. This sensor is ratiometric.
The 20 Amp Current Sensor AC/DC measures up to 20 A AC and –20 A to +20 A DC, offering separate ratiometric outputs for AC and DC components. It is a ratiometric sensor designed for use with PhidgetInterfaceKit and PhidgetTextLCD devices.
The manual explains hardware installation, connection of the sensor cable to a PhidgetInterfaceKit, software setup on Windows or Mac OS X, and how to interpret sensor values using provided formulas. Detailed device specifications, connector pinouts, and alternative interface options are also included.
