DHR 400 C420
VFD and SCR waveforms current measurement
True RMS output
4-20 mA current output
Eliminates insertion loss
Isolated plastic case recognized according to UL94-V0
Large aperture for cable up to Ø32mm
High isolation between primary and secondary circuits
VFD Controlled Loads
VFD output indicates how the motor and attached load are operating.
SCR Controlled Loads
Acurate measurement of phase angle fired or burst fired (time proportioned) SCRs. Current measurement gives faster response than temperature measurement.
Switching Power Supplies and Electronic Ballasts
True RMS sensing is the most accurate way to measure power supply or ballast input power.
