AC/DC Current transducer DHR-C420
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 4-20mA
current output.

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.
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 I
PN
, whereas the output is limited by
the above specified output limitation.
