We all need to use electricity meters, so we need to know something about electricity meters. Today we will talk about the mechanical kWh meter .
The voltage line and the current line in the mechanical watch are separated. The voltage line provides an alternating electric field, and the current circuit provides an alternating magnetic field. The two alternating fields generate the driving force on the aluminum plate that is less than the middle to make it rotate. This is the machine. The working principle of an electric energy meter.
The measurement accuracy of the mechanical kWh meter is 0.5, which realizes the on-site LED display and remote RS485 digital interface communication, and adopts the MODBUS-RTU communication protocol. It is equipped with a universal (AC/DC) switching power supply input interface. Unless otherwise stated, it is a standard product with a 220V (AC/DC) or 110V (AC/DC) power interface. The working power supply voltage of the instrument is AC/DC: 80-270 volts. Please ensure that the provided power supply is suitable for this series of products to avoid damage to the product.
This is the end of the understanding of the mechanical kWh meter. For more details, please visit the single phase energy meter . yhddb.com
