LEM DHR 400 C420, Hall Effect Current Sensor, 400Amp , True RMS 4-20mA output
Compact and versatile transducers for high AC and DC currents from 100 to 1000A 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
- VFD and SCR waveforms current measurement
- True RMS output
- 4-20mA current output
- Panel mounting
- Eliminates insertion loss
- Isolated plastic case recognised according to UL94-V0
Advantages
- Large aperture for cable up to ?32mm
- High isolation between primary and secondary circuits
- Easy installation
Applications
-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. Current measurement gives faster response than temperature measurement
-Application Domain
Energy and Automation
