LP-TPR Tap Position Transducer

LP-TPR Tap Position Transducer

The LP-TPR resistance type tap position transducer converts a potentiometric voltage into a load independent dc current signal.
The unit provides an excitation voltage for the external resistor chain or potentiometer.
Power for the unit is derived from an external supply.
