AC/DC Current transducer DHR-C420 IPN = 100..1000 A  
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.

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 IPN, whereas the output is limited by  
the above specified output limitation.
