In today’s fast-evolving energy landscape, smart power meters have become indispensable tools for energy integrators, utilities, and building automation providers. With increasing demand for real-time data, system integration, and remote monitoring, selecting the right smart power meter is no longer just a hardware decision — it’s a strategy to future-proof energy management.
As a trusted IoT hardware provider, OWON Technology offers a comprehensive range of smart power meters designed for flexible deployment and seamless integration. In this article, we explore the top 5 smart metering solutions tailored for energy integrators in 2025.
1. PC311 – Compact Single-Phase Power Meter (ZigBee/Wi-Fi)
Ideal for residential and small commercial projects, the PC311 is a single-phase smart meter that combines compact size with powerful monitoring capabilities. It supports real-time measurement of voltage, current, active power, frequency, and energy consumption.
Key Features:
Built-in 16A relay (dry contact optional)
Compatible with CT clamps: 20A–300A
Bidirectional energy measurement (consumption & solar generation)
Supports Tuya protocol and MQTT API for integration
Mounting: Sticker or DIN-rail
This meter is widely adopted in home energy management systems and rental property monitoring.
2. CB432 – Smart Din-Rail Switch with Power Meter (63A)
The CB432 serves dual functions as a power relay and smart meter, making it ideal for load control scenarios such as HVAC units or EV charging stations.
Highlights:
63A high-load relay + energy metering
ZigBee communication for real-time control
MQTT API support for seamless platform integration
System integrators prefer this model for combining circuit protection and energy tracking in one unit.
3. PC321 – Three-Phase Power Meter (Flexible CT Support)
Built for industrial and commercial projects, PC321 supports single-phase, split-phase, and three-phase systems with CT ranges up to 750A.
Standout Features:
Full-range CT compatibility (80A to 750A)
External antenna for extended signal range
Real-time monitoring of power factor, frequency, and active power
Open API options: MQTT, Tuya
It’s widely used in factories, commercial buildings, and solar systems.
4. PC341 Series – Multi-Circuit Monitoring Meters (Up to 16 Circuits)
The PC341-3M16S and PC341-2M16S models are designed for submetering applications where monitoring individual circuits is critical — such as apartments, hotels, or data centers.
Why Energy Integrators Love It:
Supports 16 circuits with 50A sub-CTs (plug & play)
Dual-mode for single-phase or three-phase mains
External magnetic antenna and high accuracy (±2%)
MQTT API for integration with custom dashboards
This model enables granular energy tracking without deploying multiple meters.
5. PC472/473 – Versatile ZigBee Power Meters with Relay Control
For integrators needing both monitoring and switching capabilities, the PC472 (single-phase) and PC473 (three-phase) are excellent choices.
Technical Advantages:
Built-in 16A relay (dry contact)
DIN-rail mountable with internal antenna
Real-time monitoring of voltage, power, frequency, and current
ZigBee 3.0 compliant and supports MQTT API
Compatible with multiple CT clamp sizes: 20A–750A
These meters are perfect for dynamic energy platforms that require automation triggers and energy feedback.
Built for Seamless Integration: Open API & Protocol Support
All OWON smart meters come with support for:
MQTT API – for integration with private cloud platforms
