Smart Energy Monitoring and Load Control
The PC473-Z enables continuous energy monitoring by connecting current clamps directly to power cables. This non-intrusive measurement method allows accurate tracking of power consumption without disrupting existing wiring.
By combining energy measurement and relay control, the PC473 supports:
• Real-time load monitoring
• Remote switching of connected circuits
• Schedule-based load management
• Energy optimization strategies in smart buildings
This makes the PC473 well-suited for energy monitoring systems (EMS) and automation platforms that require both visibility and control.
Application Scenario
The PC473-Z is suitable for a wide range of smart energy and automation projects, including:
• Sub-metering and relay control in residential or light commercial buildings
• Energy monitoring in smart buildings and property management systems
• Integration into Tuya-based platforms for centralized energy visibility
• Load shedding and schedule-based control in smart panels
• Customized energy monitoring devices for HVAC systems, EV chargers, and high-demand equipment
• Smart grid pilots and distributed energy management projects
