Product Overview

Product Features

  • Safe and reliable

The voltage input employs a high-voltage isolation module (2000 V, with a response time ≤ 2 μs), while the current input utilizes an AC current clamp (0–50 kHz, 0–5 A rms), ensuring safe isolation between the input signal and the measurement system. This design not only makes the MC-PQ1100B safe, reliable, and easy to use, but also significantly enhances its immunity to electromagnetic interference.

  • High precision

Both harmonic analysis and three-phase unbalance measurement employ reference algorithms with no approximations, utilizing high-precision 16-bit A/D converters for simultaneous sampling at a rate of 12.8 kHz.

  • Powerful software features

Employing a DSP+ARM+CPLD core architecture, this solution delivers high processing speed and robust software functionality, making it well-suited for complex testing and data-processing tasks and significantly enhancing testing efficiency and performance.

  • Many test parameters

System frequency, power grid harmonics, three-phase voltage unbalance, voltage deviation, voltage swells and sags, fundamental voltage RMS and true RMS values, fundamental current RMS and true RMS values, fundamental active power, reactive power, fundamental apparent power, harmonics from the 2nd to the 50th order, and true power factor, among others.

  • Real-time Harmonic Data Assessment

The instrument is preloaded with the national standard limits for harmonics, enabling accurate, real-time assessment of whether the measured voltage and current harmonic data are within acceptable limits or exceed them.

  • Communication Interface

The power quality analyzer is equipped with two USB ports: one host port for storing data on a USB flash drive, and one device port for communication with a laptop to enable data transfer and analysis.

  • Internal functional output

Built-in 128 MB of memory for data storage in 3-second, 5-second, 10-second, and 30-second intervals.

  • Data Graphical Display

5.5-inch color LCD display, capable of showing spectrum plots, waveform graphs, and real-time data, providing intuitive and clear visualization.

  • Real-time printing

This instrument is equipped with a miniature thermal printer, enabling on-demand printing of real-time field test data.

  • Easy to use

Portable design with compact dimensions: overall dimensions (mm): 320 × 280 × 135 (length × width × height); lightweight: the instrument weighs only 3.5 kg, allowing a single person to carry it to the field for on-site testing; built-in high-performance lithium battery enables continuous operation for 8 hours without an external power supply.
