1. Product Overview:
Three-phase digital ammeter tunes CT parameters and PT parameters through panel key, and display a running system visually, three rows of LED display three-phase value clearly, It can replace traditional analog pointer meter. It is a kind of high-performance automatic meter which is suitable for industrial and mining enterprises, civil construction, building automation and some other modern distribution system.
2. Main features:
2.1 Four bits LED display type, 0~9999
2.2 High bit AD conversion, high precision.
2.3 Single chip design, strong anti-jamming performance
2.4 With a number of menu programming, flexible operations
2.5 accurate measurement, reliable performance
2.6 It is easy to expand functions, and it can extend to alarm output and programmable unit.
3. Standard Configuration:
3.1 Meter measures high/low voltage three-phase current value on the grid. It shows high precision for digital zeroing, digital tuning. This product is cost-effective.
3.2 Standard CT inputs, standard PT input or input directly.
3.3 A wide range of AC and DC universal power supply: AC/DC80-265V or AC220V.
3.4 Three rows of four LED real-time digital display, and the meter can set display value through display panel button.
3.5 It uses the installation of disk opening with a hole.
