Voltage Transducer LV 25-P  
IPN = 10 mA  
For the electronic measurement of voltages : DC, AC, pulsed...,  
with a galvanic isolation between the primary circuit (high voltage)  
and the secondary circuit (electronic circuit).

must be passed through an external  
resistor R 1 which is selected by the  
user and installed in series with the  
primary circuit of the transducer.
