Product Overview

  • The MC-PQ600 is widely applicable in power transmission and distribution, power electronics, motor drives, and other fields.
  • Measure and analyze the AC power quality of the public grid as it is supplied to the user end.
  • Wavelet transform is applied to measure and analyze the harmonics of non-stationary time-varying signals.
  • Measure and analyze the impact of various electrical loads on the power quality of the public grid under different operating conditions.

Product Features

  • Safe and reliable

The voltage input employs a high-voltage isolation module (2000 V, response time ≤ 2 μs), while the current input uses an AC current clamp (0–50 kHz, 0–5 A rms), ensuring safe isolation between the input signal and the measurement system. This not only makes the MC-PQ600 safe, reliable, and easy to use, but also significantly enhances its immunity to electromagnetic interference.

  • 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 and is equipped with a high-performance lithium battery, enabling continuous operation for 8–10 hours without an external power supply.

  • 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 with a built-in WINCE operating system and a touch-screen display, the MC-PQ600 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.

  • Communication interface

The power quality analyzer is equipped with a USB interface for convenient data storage on a USB flash drive.

  • Many test parameters

System frequency, power grid harmonics, three-phase voltage unbalance, voltage deviation, frequency deviation, electrical energy statistics, voltage swells and sags, current surges, root mean square voltage, root mean square current, active power, reactive power, apparent power, true power factor, interharmonics, and harmonics from the 2nd to the 63rd order—these are the five major parameters specified in China’s national standards for power quality.

  • It features a built-in high-capacity data storage card that can continuously record data at 1-minute intervals for more than 18 months, thereby meeting the needs of long-term monitoring at test sites.
  • It can display the vector diagram of the measured voltage and current, allowing users to determine whether the metering equipment is wired correctly based on the diagram.
  • This instrument can directly measure DC voltage.
  • Backend Management Analytics Software

PQMS Power Quality Management Analysis Software is a back-end management and analysis application for power quality, running on the Windows XP or Windows 2000 operating system. For detailed information, please refer to the software user manual.
