Features
● VFD and SCR waveforms current
measurement
● True RMS output
● Panel mounting
● Eliminates insertion loss
● Isolated 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
AC/DC Current Transducer DHR-C5
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 0-5V
voltage output.

Notes :1) 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
I
PN, whereas the output is limited by the above specified output limitation.
2)
According to the UL 508 Standard for Safety for Industrial Control
Equipment, the supply voltage must not exceed 42VDC.
