Moving coil measuring instrument PR series

voltagecurrentindustrial

The moving-coil rectifier panel meter are suitable for measuring sinusoidal AC currents and voltages. The frequency range for voltmeters an milliammeters up to 600 mA is 25 to 10.000 Hz. For current higher than 1A - 5A, the frequency can not exceed 50 or 60 Hz. (On request: 400 Hz). It is possible to measure higher currents and voltages connecting the instruments through suitable measuring transformers. Electrical data Overload capacity according to DIN 43780 Continuously 1,2 times rated value Short duration 10 x IN 5 s ammeters 2 x UN 5 s voltmeters The setting time is approximately 1 minute. Consumption Voltmeterr: aprox.. 1 mA Ammeter: up to 800 mA: 1 up to 1.5 V voltage drop from 800 mA: aprox. 0.25 VA Moving coil instruments with rectifier SSelf-shielding moving-coil rectifier system, with core magnet movement and hairsprings for the creation of the restoring torque. Pivot suspension with spring loaded jewel bearings for vibration and shock resistance. Scales 90º scale (PR..)/ 240º scale (PAR...n), practically linear. Slightly compressed at the beginning for voltmeters under 40V. The graduations at the beginning of the scale are electrically suppressed in rated value voltmeters. o-fino. • For direct measurement of the alternating current and voltage or • For connection at the current and voltage transformer • Class 1.5
