Overview

Q96-RZC Q72-RZC Q144-RZC Voltmeter AC is embedded in the power equipment installed on ships or other occasions to measure the AC voltage and AC current with rated working frequency of 50Hz and 60Hz. It measure the effective value of AC voltage and AC current, Overall dimensions...... din43700, Comply with marine codes and IEC standards. The selection of common Voltmeter AC should generally make the indication value about 2 / 3 of the full scale of the dial. For example, a voltmeter with a full scale of 500V should be selected for 380V, and a voltmeter with a full scale of 300V or 400V should be selected for 220V. High voltage voltmeters are used together with voltage transformers. For example, a voltmeter with 6000 / 100 on the dial shall be selected for 6kV and a voltmeter with 10000 / 100 on the dial shall be selected for 10kV. We call 6000 / 100 and 10000 / 100 transformation ratio, and the transformation ratio of voltage transformer is the same. The wiring of AC voltmeter is regardless of polarity, but in a system, the wiring of all voltmeters shall be consistent, especially 220V or voltmeter using transformer must comply with this rule. AC voltmeter and its voltage transformer circuit must be equipped with fuse to prevent short circuit.

Working principle 

We measure Voltmeter AC, which is generally expressed by AC RMS, because AC 220V and DC 220V ignite the same bulb with the same luminous effect. That is, the electric power generated is the same The alternating current is first detected into pulsating direct current, and the deflection of Al pointer of current meter is directly proportional to the current. Due to mechanical inertia, the average effect of deflection force per moment is equivalent to the deflection effect of a direct current passing through the meter

Features

1) High input impedance: generally, the input resistance is at least 500K Ω. After the instrument is connected to the tested circuit, it has little impact on the circuit.

2) Wide frequency range: the applicable frequency range is about several hertz to several thousand megahertz.

3) High sensitivity: microvolt level can be measured at the lowest voltmeter.

4) Wide range of voltage measurement: the range of the instrument can range from hundreds of volts to 1 mV.
