AD-PQMON-SL – An Evaluation Platform for Power Quality Monitoring
1. OverviewssIn industrial facilities, power infrastructure, and building energy systems, accurate power quality (PQ) monitoring is critical. Issues such as voltage sags, surges, harmonics, and frequency variations can lead to equipment degradation and unexpected system failures.
AD-PQMON-SL is a power quality monitoring evaluation platform from Analog Devices, designed to help engineers quickly evaluate and validate power quality measurement and analysis before deploying a full system.
This article introduces the architecture, key features, and typical use cases of the AD-PQMON-SL evaluation board.
2. What Is AD-PQMON-SL?
AD-PQMON-SL is a power quality monitoring evaluation platform with the WIZnet WIZ850io Ethernet module already integrated.
It combines Analog Devices’ high-precision power quality measurement ICs with WIZ850io, a hardware TCP/IP–based Ethernet module, enabling out-of-the-box network connectivity.
Key elements of the platform include:
- High-accuracy voltage, current, and power quality measurement (Analog Devices)
- MCU-based data processing
- Built-in Ethernet communication via WIZnet WIZ850io
With this architecture, AD-PQMON-SL allows engineers to evaluate remote, network-based power quality monitoring without adding external Ethernet hardware.
3. Key Features and Capabilities
3.1 High-Accuracy Power Quality Measurement
AD-PQMON-SL supports measurement of key power quality parameters, including:
- RMS voltage and current
- Active, reactive, and apparent power
- Line frequency
- Harmonic and distortion analysis
These capabilities are essential for industrial power monitoring and energy management systems.
3.2 Power Quality Event Detection
- Voltage sags and swells
- Momentary interruptions and surge events
- Detection of abnormal power conditions
Such event detection is crucial for equipment protection and predictive maintenance.
3.3 Evaluation-Oriented Design
- PC software provided by Analog Devices
- Real-time data monitoring and logging
- Optimized for algorithm validation and system tuning
4. Application Scenarios

One of the key strengths of AD-PQMON-SL is that the WIZnet WIZ850io Ethernet module is already integrated into the platform.
This enables a complete evaluation flow—from power quality measurement to Ethernet-based data transmission—on a single board.
4.1 Ethernet Transmission of Power Quality Data
- ADI power quality ICs: measure voltage, current, harmonics, and PQ events
- MCU: data collection and packet processing
- WIZ850io: hardware TCP/IP–based Ethernet communication
Measured power quality data can be transmitted via TCP or UDP to servers, SCADA systems, or cloud platforms in a stable and predictable manner.
4.2 Remote Power Quality Monitoring Evaluation
- Real-time monitoring of power quality in industrial panels or facilities
- Centralized data collection over Ethernet networks
- Visualization and analysis via PC software, dashboards, or cloud services
Thanks to WIZ850io’s hardware TCP/IP offload, MCU load is minimized, ensuring both measurement accuracy and communication reliability.
4.3 From Evaluation Board to Production Design
AD-PQMON-SL also provides a clear path toward production systems:
- Validate power quality measurement and Ethernet communication using AD-PQMON-SL
- Design a custom board using the same ADI measurement ICs and WIZ850io
- Reuse the proven network architecture in mass-production products
This creates a smooth development path from evaluation → PoC → production.
5. Advantages of Analog Devices Power Solutions

Analog Devices has extensive experience in power and energy measurement technologies.
- High measurement accuracy and reliability
- Proven performance in industrial and power infrastructure environments
- Long-term product availability and strong technical support
These strengths are critical for power systems designed for long-term operation.
6. Conclusion
AD-PQMON-SL is a practical and powerful platform for evaluating power quality monitoring systems.
It provides reliable measurement data even in complex power environments, enabling stable and confident system design from the early development stages.
For projects requiring detailed power quality analysis, AD-PQMON-SL is an excellent starting point.
