Caution, risk of electrical shock When operating the transducer, certain parts of the module can carry hazardous voltage (eg. primary busbar, power supply). Ignoring this warning can lead to injury and/or cause serious damage. This transducer is a build-in device, whose conducting parts must be inaccessible after installation. A protective housing or additional shield could be used. Main supply must be able to be disconnected.

Instructions for use of the voltage transducer model LV 25-P Primary resistor R: the transducer’s optimum accuracy is obtained at the nominal primary current. As far as possible, R should 1 1 be calculated so that the nominal voltage to be measured corresponds to a primary current of 10 mA. Example: Voltage to be measured V = 250 V a) R = 25 kΩ / 2.5 W, I = 10 mA Accuracy = ± 0.9 % of V (@ T = + 25 °C) PN 1 P PN A b) R = 50 kΩ / 1.25 W, I = 5 mA Accuracy = ± 1.5 % of V (@ T = + 25 °C) 1 P PN A Operating range (recommended): taking into account the resistance of the primary windings (which must remain low compared to R, in order to keep thermal deviation as low as possible) and the insulation, this transducer is suitable for measuring nominal 1 voltages from 10 to 500 V.
