Mashhad Tadbir - W27 Power Analyzer

The W27 series power quality analyzer is a precise measurement center for real-time monitoring of three-phase electrical networks, designed with a high accuracy, event recording capability, and support for RS-485 (Modbus RTU) communication.
This series includes three models: W2710, W2720, and W2730.

Technical Specifications and Model Comparison

Why Is the W27 Series a Smart Choice for You?

If you are looking for an accurate, economical, and fully reliable power quality analyzer, the W27 series is exactly the device you need. It is designed for projects that require comprehensive electrical parameters measurement but do not want to pay a high cost for advanced and complex features.

✔ If you require measure the main electrical parameters with high accuracy:
Including voltage, current, active and reactive power, power factor (PF), frequency, and THD.

✔ If you need harmonic analysis:
The W2720 model measures harmonics up to the 15th order, and the W2730 model measures harmonics up to the 31st order.

✔ If your project requires stable industrial communication:
Full support for RS-485 (Modbus RTU) for connection to PLC, BMS, and monitoring systems.

✔ If you do not require such as Wi-Fi, data logging, or complex settings:
The W27 is a simple, easy-to-understand, and practical device that covers basic to semi-advanced needs without unnecessary complexity.

✔ If your project requires a large number of devices:
The competitive price of the W27 significantly reduces the total project cost.

✔ If you are looking for a device with simple installation and commissioning:
The W27 is a completely straight for ward choice for technicians and electrical operators.
