Currently, the power monitoring field is plagued by the pain points of data dispersion and system fragmentation. Traditional single-function electricity meters lead to low efficiency in energy efficiency management and high operation and maintenance costs. We adopt a fusion solution of multi-core processors and intelligent algorithms, and through integrated design, the Multifunctional Power Meter simultaneously realizes three functions: power quality analysis, load forecasting, and fault early warning. Measured data shows that this solution reduces the comprehensive operation and maintenance cost by 42%, and shortens the fault response time to 2.1 minutes, perfectly meeting the refined management needs of industrial power grids and smart buildings.
Core technical advantages
- 128th harmonic analysis: Supports simultaneous monitoring of THDu/THDi with accuracy meeting IEC 61000-4-30 Class S standard

- Anti-misoperation design: Equipped with three-level password protection and operation log tracking function
Installation and operation guidelines
① It is recommended to calibrate the voltage transformer accuracy every quarter (error ≤ ±0.5%)
② Ensure environmental humidity ≤ 85% RH for long-term operation
③ Firmware supports remote online upgrade
Frequently Asked Questions
Q: Is it possible to upgrade the existing system?
A: The standard DIN rail installation design is fully compatible with the traditional Multi-Function Ammeter installation dimensions, and the upgrade process does not require power distribution interruption.
Q: What is the maximum number of scalable measurement channels?
A: The basic configuration has 12 measurement channels, which can be expanded to 36 channels through expansion modules, supporting full parameter measurement for three-phase four-wire systems.
Q: How is the security of data storage ensured? A: Dual backup storage using EEPROM and SD card is adopted, with data retention time of ≥ 10 years after power-off, meeting the GDPR data security standards.
Q: How is the adaptability in extreme environments?
A: The operating temperature range is -25℃ to 70℃, with a protection level of IP54. It has passed the 5g vibration test and the 10kV pulse group anti-interference certification.
The practice of a certain intelligent manufacturing factory shows that after the deployment of the Multifunction Meter system, the monthly peak-valley balance rate of electricity consumption has increased by 38%, and the capture rate of power quality events has reached 100%. Its unique load pattern learning function can automatically identify the operating status of equipment and generate an optimized electricity usage plan, providing data support for the energy-saving transformation of enterprises. This technical solution that integrates measurement, analysis, and early warning has redefined the value positioning of power metering equipment in the era of the energy internet.
