Technical Specifications

Overall dimensions




Note: If instruments are installed side by side on a unified horizontal plane, it is recommended to have instrument openings spaced 30mm apart.
Application requirements: Real time monitoring of voltage, current, power, and energy consumption in the electrical circuit of the production line, analysis of harmonic distortion and three-phase imbalance issues, to ensure the safe operation of equipment.
Instrument advantages: high-precision measurement (± 0.2% error) and power quality analysis function, can capture voltage fluctuations, frequency deviations and other abnormalities, and connect to industrial automation systems through Modbus protocol to achieve energy consumption statistics and fault warning.
Application requirements: Conduct sub metering of power distribution systems in shopping malls, office buildings, and other buildings, calculate the electricity consumption of lighting, air conditioning, power, and other circuits, and optimize energy allocation.
Instrument advantages: Supports multi rate energy statistics and extreme value recording (including timestamps), can be connected to building automation systems through Ethernet modules (MODBUS-TCP), and combined with FTP protocol to achieve remote data upload and report generation.
Application requirements: Wind and photovoltaic power stations need to monitor the quality of grid connected electricity to ensure that harmonic content and voltage fluctuations comply with grid standards, while recording power generation and grid connected electricity.
Instrument advantages: Wide range auxiliary power supply (AC/DC 85-300V) adapts to voltage fluctuations in new energy power plants, UL certification ensures grid compliance in the North American market, and harmonic analysis function meets the technical requirements for grid access.
Application requirements: Export projects must comply with local electrical standards (such as UL in North America and CE in Europe) and adapt to different power grid standards (such as 60Hz frequency and 115V voltage).
Instrument advantages: Multiple certification coverage (UL, CE, CPA), support 50Hz/60Hz dual frequency, adapt to multiple voltage levels from 66V to 690V, expand Ethernet communication for remote operation and maintenance, making it an ideal choice for Chinese manufacturing supporting exports.
