AC/DC Current transducer DHR-C10
The transducer for the electronic measurement of DC & distorted AC
waveform currents, with galvanic isolation between the primary circuit
(power) and the secondary circuit (measurement). True RMS 0-10V
voltage output.

Note :
(*) The Max. Peak AC Current is the highest peak level of the primary signal that is
taken into account for accurate True RMS calculation. Yet the device is designed for
maximum continuous True RMS value equal to IPN, whereas the output is limited by
the above specified output limitation.
Features
• VFD and SCR waveforms current
measurement
• True RMS output
• Panel mounting
• Eliminates insertion loss
• Insulated plastic case recognized
according to UL94-V0
Advantages
• Large aperture for cable up to
Ø32mm
• 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
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.
Application domain
• Energy and Automation
