AC/DC Current transducer AHR-B5  
IPN = 500 .. 2000 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 0-5 V voltage output.

Continuous condition minitoring  
allowing automatic failure detection/  
anticipation.  
Note : 1) The max. peak AC current is the highest peak level of the primary signal that is  
taken into account for accurate True r.m.s. calculation.  
Yet the device is designed for maximum continuous true r.m.s. value equal to IPN  
whereas the output is limited by the above specified output limitation.
