Instructions for use of the voltage transducer model LV 25-P

Primary resistor R

s optimum accuracy is obtained at the nominal primary current. As far as possible, R

calculated so that the nominal voltage to be measured corresponds to a primary current of 10 mA .

Example: Voltage to be measured V

a) R

W, I

Accuracy = ± 0.8 % of V

b) R

5 mA

Accuracy = ± 1.6 % of V

Operating range (recommended) : taking into account the resistance of the primary windings (which must remain low compared to R

to keep thermal deviation as low as possible) and the isolation, this transducer is suitable for measuring nominal voltages from 10 to 500 V.
