For alternating current 15 - 100 Hz Class 1.5 Description The moving-iron panel meters are mainly used for measuring AC currents and voltages in the frequency range of 15 ... 100 Hz. They indicate the rms value of the wave, even with high harmonics, with a minor ininfluence on the accuracy. Our instruments are normally calibrated for sinusoidal AC. For current above 100A or high voltages, the instruments must be connected through measuring transformers. Movin iron instruments can be connected in any order without observation of polarity (ki) on the current transformer. Electical Data Overload capacity according to DIN 43780 Continuously 1,2 times rated value Short duration 10 x IN 5 s in ammeters 2 x UN 5 s in voltmeters The setting time is approximately 1 minute. Mounting in DIN rail (EQ35n) For measuring current and voltage in panel boards with 35 mm DIN rail according DIN 50 022. Dimensions: 85 x 45 x 65 mm / Weight: 0.1 Kg The instruments of this line are adapted by their dimensions to common installations devices. The installation width of the instruments of 45 mm corresponds approx. for 3 units. They can easily mounted on DIN rail bars by snap on mounting. The terminals are protected against accidental contact. The movin iron meter is jewelled with silicon oil damping. Comsumption Amperimetro max. 0,5 VA Ammeters more than 15 A 0,8 VA Moving iron instruments Moving-iron movement with silicone oil damping. Pivot suspension with spring loaded jewel bearings for vibration and shock resistance. Scales 90° scale, cmpressed at the beginning. Coarse-fine division. For ammeters with overload scaling, it covers between 10% (for 1,2In) y el 35% (for 5In) of the total scale lenght. Table for norm scales of voltmeters for connection to voltage transformer * Voltmeter for connection to voltage transformer: The final scale value is 1.2 times the rated voltage, for example: for connection to transformer sec. 100 V the measuring range is 0...120 V for connection to transformer sec. 110 V the measuring range is 0...132 V Please indicate primary voltage, scale and secondary voltage when ordering..
