Introduction
To get the output signal that is proportional to the input signal, we use a component called a transducer. There are different transducers, including DC and AC voltage transducers. They are to produce a voltage output or DC current proportional to the AC input voltage and currently got from the unit. AC transducers separate input voltages from the transducer and are for transformer input. Thus, in this article, we are going to discuss the LEM LV 25-P VOLTAGE TRANSDUCER.
Overview of LEM LV 25-P VOLTAGE TRANSDUCER
LEM LV 25-P is a voltage transducer module, for electronic voltage measurements (DC, AC, pulsed, etc.) with galvanic isolation between the primary and secondary circuits. This voltage transducer is based on the Hall effect and may be mounted on a PCB. Between primary and secondary circuits, the device offers galvanic isolation. To measure a voltage, a current proportional to the measured voltage must be collected through an external resistor chosen by the user. Hence it is suitable for voltages related to DC, AC, and impulse circuits, which may be measured electronically with this device.
