LEM AHR 1000 B420, Hall Effect Current Sensor, 1000Amp, True RMS 4-20mA output, 104 x 40mm aperture
Compact and versatile transducers for high AC and DC currents from 500 to 2000A True RMS with signal conditioning. Choice of output types: 4-20 mA, 0-5 V or 0-10 V, Bandwidth: DC 20..6000 Hz
True RMS sensing - the most accurate way to monitor power supply or input power
VFD output indicates how the motor and attached load are operating
Accurate measurement of phase angle fired or burst fired(time proportional) SCR's and switch mode rectifiers. Current measurement gives faster response than temperature measurement.
Continuous condition monitoring allowing automatic failure detection and prediction
