The W28 series is an advanced, intelligent, and professional power quality analyzer designed for projects that require data logging, smart monitoring, modern communication interfaces, and accurate harmonic analysis.

Equipped with a large and clear LCD display, this series provides operators with a fast, simple, and user-friendly interface.

In addition to comprehensive electrical parameters measurement—voltage, current, power, power factor (PF), frequency, THD, and unbalance—the W28 series offers professional data logging capabilities. Some models are also equipped with built-in Wi-Fi and the DNP3 protocol, making them suitable for advanced monitoring systems, dispatching applications, and industrial automation.

The W28 series includes the following models:
W2810, W2811, W2812, W2820, W2821, W2830, W2835, W2836, W2840, and W2845.
Each model differs in terms of harmonic analysis level, measurement accuracy, communication capabilities, and project application.

With this wide range of models, you can select the most suitable option based on your budget, project scale, and technical requirements.

In the table below, you can see the differences between the W28 models at a glance.

Why Is the W28 Series a Professional and Future-Ready Choice?

✔ If you are looking for an advanced and intelligent power quality analyzer for professional projects:
The W28 series is specifically designed for this level of requirement. It is ideal for projects that, in addition to complete electrical measurements, require data logging, advanced analysis, modern communication, and ease of use.

✔ If you need detailed reporting and advanced analysis beyond basic measurement:
The W28 series supports data logging of up to 18,000 records, enabling analysis of consumption trends, peak demand, voltage dips, and power quality over different time periods.

✔ If a professional harmonic analysis is required:
Depending on the model, the W28 series supports harmonic measurement up to the 16th, 312st, and even 41th order, making it highly suitable for UPS systems, inverters, data centers, and sensitive industrial applications.

✔ If you require modern and advanced communication capabilities:
In addition to RS-485 (Modbus RTU) communication, some W28 models support the DNP3 protocol and feature built-in Wi-Fi, which is a major advantage for dispatching systems, substations, and professional automation projects.

✔ If ease of operation and display readability are important to you:
The W28 series is equipped with a large, high-contrast LCD display that offers significantly better readability, simpler menus, and faster configuration compared to 7-segment and dot-matrix displays.

✔ If your project requires smart monitoring and data recording:
The W28 series is designed for use in BMS, SCADA, energy management systems, and smart infrastructure projects, providing professional-grade data recording, analysis, and utilization capabilities.

✔ If high measurement accuracy is critical for your application:
In high-end W28 models, energy measurement accuracy is improved to 0.5%, which is essential for sensitive projects such as healthcare facilities, data centers, and precision production lines.

✔ If you are looking for a long-term and future-oriented investment:
With up-to-date features, advanced communication options, and deep analytical capabilities, the W28 series is an excellent choice for projects that are expected to operate reliably for many years without frequent device replacement.
