In modern power distribution systems, precise measurement of electrical parameters, energy metering, and reliable monitoring of equipment operating status are fundamental to ensuring power supply safety and achieving energy efficiency management. Various types of embedded power meters serve as key measurement components, widely used in incoming and outgoing cabinets, providing data support for system operation.
Among embedded energy meter products, the APM series is typically used for incoming circuits, featuring multi-rate metering, harmonic measurement, and voltage sag/swell monitoring. Its modular design allows users to expand functional modules based on actual needs, such as adding analog input/output, digital control, or various communication interfaces (e.g., Profibus-DP, Modbus-TCP), enhancing configuration flexibility.

For environmental monitoring, temperature and humidity controllers such as the WHD series can be used for automatic dehumidification in distribution boxes and switchgear, preventing equipment failures caused by humidity. Their accompanying heaters can be selected based on the space volume to achieve precise temperature control. Additionally, small temperature and humidity detection modules can be integrated into the system via RS485 interface to monitor environmental parameters in real-time at multiple points, suitable for substations, warehouses, and other scenarios.

In practical projects, such as the Shenzhen Sea World Cultural Arts Center, embedded energy meters are installed in the metering control box to achieve precise metering and monitoring of the power circuit. Related products all possess type approval certificates, CE certification, and other qualifications, ensuring compliance with national metering and safety standards.
