LV 25-P/SP5

LV 25-P/SP5 is a LV25 series voltage transducer for the electronic measurement of DC, AC, pulsed voltages with galvanic separation between the primary circuit and the secondary circuit. For voltage measurements, a current proportional to the measured voltage must be passed through an external resistor R1 which is selected by the user and installed in series with the primary circuit of the transducer. The voltage transducer is suitable for use in single or three phase inverters, propulsion and braking choppers, propulsion converters, auxiliary converters and battery chargers. It is also used at railway (fixed installations and onboard) application domain.
