WiFi Electric Meter 3 Phase with 16A Relay for Smart Energy Monitoring

Why WiFi Electric Power Meters Are Becoming Essential in Modern Energy Systems

As energy costs rise and electrical systems become more complex, the demand for WiFi electric power meters has increased rapidly across residential, commercial, and light industrial applications. Property managers, system integrators, and energy solution providers are no longer satisfied with basic consumption readings—they require real-time visibility, remote control, and system-level integration.

Search trends such as wifi electric power meter, 3 phase electric meter wifi, and electric sub meter wifi clearly reflect this shift. Users are not only asking how much energy is consumed, but also how to measure, control, and optimize energy usage remotely.

At OWON, we design connected energy metering solutions that address these real-world requirements. Our PC473 WiFi electric energy meter is built for both single-phase and 3-phase systems, combining precise measurement with 16A dry contact relay control for intelligent energy automation.

Understanding WiFi Electric Energy Meters

A WiFi electric energy meter is a connected device that measures electrical parameters such as voltage, current, power factor, and active power, while transmitting data wirelessly to a cloud platform or local application.

Compared to traditional meters, WiFi-enabled meters provide:

Real-time and historical energy data
Remote monitoring via mobile or web platforms
Integration with smart energy systems
Remote load control and automation

These capabilities make WiFi meters especially valuable for electric sub metering, distributed energy management, and demand-based control strategies.

Single-Phase and 3 Phase Electric Meter WiFi: One Platform, Multiple Scenarios

Many projects require flexibility across different electrical architectures. The PC473 is designed to support both single-phase and 3-phase electric systems, allowing one product platform to serve multiple applications.

Typical scenarios include:

Single-phase sub metering in residential or small commercial buildings
3 phase energy monitoring in light industrial facilities
Multi-circuit monitoring using external current clamps
Distributed panels requiring scalable metering solutions

By supporting a wide current range (20A to 1000A clamp options), the PC473 adapts easily to different load conditions without changing the core device.

Why a 16A Dry Contact Relay Matters in Smart Energy Systems

Many energy meters stop at measurement. However, modern energy control requires action, not just data.

The 16A dry contact relay integrated into the PC473 enables:

Remote ON/OFF control of electrical loads
Schedule-based energy management
Load shedding during peak demand
Automated control based on energy thresholds

This combination transforms the meter from a passive monitoring device into an active energy control node, suitable for smart panels, energy automation, and load management applications.

Key Technical Capabilities of the PC473 WiFi Electric Power Meter

The PC473 is designed with both measurement accuracy and system integration in mind:

WiFi 2.4GHz connectivity for stable data transmission
Measures voltage, current, power factor, frequency, and active power
Energy usage and production tracking with hourly, daily, and monthly trends
Fast reporting cycles (energy data every 15 seconds)
DIN rail mounting for professional electrical panels
Lightweight clamp-based installation without breaking circuits
Tuya platform compatibility for rapid ecosystem integration

These features allow the PC473 to serve as a smart wifi electric power meter suitable for a wide range of deployment environments.

Typical Applications of WiFi Electric Sub Meters

Smart Buildings and Property Management

WiFi sub meters enable property managers to monitor individual circuits, tenants, or zones, improving transparency and cost allocation.

Energy Management Systems

By combining energy data with relay control, systems can optimize energy usage automatically, reducing operational costs.

Distributed Energy and Solar Monitoring

The PC473 supports both energy consumption and production measurement, making it suitable for solar-integrated systems.

Smart Panels and Load Automation

DIN rail installation and relay output allow seamless integration into smart electrical panels and control cabinets.

How WiFi Electric Meters Support Smarter Energy Decisions

Data alone is not enough. What matters is how that data is used.

With real-time visibility and remote control, WiFi energy meters support:

Energy efficiency analysis
Preventive maintenance
Automated response to abnormal loads
Integration with HVAC, EV charging, and other high-demand systems

This is where connected metering becomes a foundational component of modern energy infrastructure.

FAQ: Common Questions About WiFi Electric Power Meters

Considerations for System Integration and Deployment

When selecting a WiFi electric energy meter for real projects, it is important to evaluate:

Measurement accuracy under different load conditions
Communication stability
Control capability (relay vs monitoring-only)
Platform compatibility
Long-term scalability and maintenance

OWON designs energy meters like the PC473 with these deployment realities in mind, ensuring they can be integrated into larger smart energy and building management systems without complexity.
