LEM AHR 2000 B420, Hall Effect Current Transducer, 2000A, 4-20mA True RMS output, 20-50VDC supply
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
Features
Split Core
VFD and SCR waveforms current measurement
True RMS output
4-20mA current output
Busbar mounting
Eliminates insertion loss
Isolated plastic case recognised according to UL94-V0
Advantages
Large aperture for cable or busbar up to 104 x 40mm
High isolation between primary and secondary circuits
Easy installation
Applications
-AC Power Supplies or Motors
True RMS sensing - the most accurate way to monitor power supply or input power
-VFD Controlled Loads
VFD output indicates how the motor and attached load are operating
-SCR Controlled Loads
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.
-Renewable Energy Installations or Backup Batteries
Continuous condition monitoring allowing automatic failure detection and prediction
-Application Domain
Energy and Automation
