The use of digital display three-phase ammeters is becoming more and more popular, and factories have entered the homes of ordinary people from the beginning. The digital display meter is an electronic instrument for performance. It focuses on the low-voltage power distribution terminal for the consumption of electric energy. In order to strengthen the measurement assessment and management of the terminal electric energy, it is convenient for users to use, transform and upgrade on-site. It is aimed at the traditional series of wall hangings. It is inconvenient to use and install the electric energy meter in the field, so it has the advantages of high measurement accuracy, strong overload capacity, stable and reliable performance, wide operating voltage range, and low power consumption. At present, it is widely used in our existence and in all walks of life. Because its performance data is accurate and clear at a glance, it has replaced the pointer type instrument in many places.
In modern electrical engineering, it has a great use. It will be very troublesome to switch between different ammeters under different conditions. Our meter solves this problem well. It can not only be applied in high-voltage and low-voltage systems, but also can measure three-phase (or single-phase) AC current values, and at the same time can realize three-phase/single-phase automatic identification. After understanding these basic knowledge, let's share with you some cold knowledge of digital display three-phase ammeter that you don't know!
It is a kind of multifunctional intelligent instrument with programmable measurement, display, digital communication and electric energy pulse transmission output. It can complete electric energy measurement, electric energy metering, data display, acquisition and transmission. It can be widely used in substation automation, power distribution automation, Electric energy measurement, management, and assessment in smart buildings and enterprises. The measurement accuracy is 0.5 grade, realizes the LED on-site display and remote RS-485 digital interface communication, and adopts the MODBUS-RTU communication protocol. Equipped with a universal (AC/DC) switching power input interface. If no special statement is made, standard products with a 220V (AC/DC) or 110V (AC/DC) power interface are provided. The operating power supply voltage of the instrument is AC/DC: 80-270V, please ensure that the provided power supply is suitable for this series of products, and the above will prevent damage to the product.
It is recommended to install a 1A fuse on the live wire side when the instrument uses AC power. For areas with poor power quality, it is recommended to install a surge suppressor in the power circuit to prevent lightning strikes and a fast pulse group suppressor. The product adopts the calculation method that each measurement channel is collected separately to ensure complete consistency and symmetry when used. The digital display three-phase ammeter has a variety of wiring methods, which is suitable for different load forms.
