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.

Applications
● VFD Controlled Loads
VFD output indicates how the
motor and attached load are
operating.
● SCR Controlled Loads
Acurate measurement of phase

● Switching Power Supplies and
Electronic Ballasts
True RMS sensing is the most
accurate way to measure power
supply or ballast input power.
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
Application domain
2)
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.
According to the UL 508 Standard for Safety for Industrial Control
Equipment the primary current must not exceed 475 A.t.RMS through the
transducer hole.
