DC frequency analysis to 170 kHz

PQ-Box 300

This mobile power quality network analyser, power meter and transient recorder allows permanent DC frequency analysis to 170 kHz. The Class A device has been developed for measurements on low, medium and high-voltage networks and is ideally designed for measurements in harsh environments or where space is very limited. In addition, the device allows the power quality of public and industrial networks to be assessed. The device is thus an essential aid for analysis in high-frequency ranges.

Permanent recording of frequencies up to 170 kHz

Computation from 8 kHz to 170 kHz takes place using a continuous FFT at 200 msec intervals. The measurement interval for the storage of measurement data can be set from 1 second to 30 minutes with 200 msec minima and maxima in each case.

WLAN interface for cableless communication with the software & app

The data recorded by the PQ-Box 300 can be transferred either by USB interface or a rapid WLAN interface to the evaluating PC. The product comes with the extensive WinPQ mobile evaluation software, which can be installed on as many PCs as you wish. To round off the excellent user experience, we have developed the PQ-Box app for both Android and iOS. The app allows you to display a wide range of online measurements and alter configurations for current and voltage transformers, measurement intervals or nominal voltages of the PQ-Box 300.

All the standards and protocols upheld – making our products fit for the future

The PQ-Box 300 creates an automatic standard assessment and event record to:

  • EN 50160 (2015)
  • IEC 61000-2-2
  • IEC 61000–2-12
  • IEC 61000-2-4 (Class 1; 2; 3)
  • NRS 048
  • IEEE 519
  • VDE N-4105
  • IEC 61000-4-30 Ed. 3 Class A

Ripple control signal analysis

In addition to measuring the ripple control level, the device is able to trigger a ripple control frequency and capture the voltages and currents for a set frequency. The complete telegram can be shown to a length of 210 seconds, while a wide range of parameters can be set in the measurement device (triggering threshold, recording threshold, ripple control frequency, bandwidth of the filter curve for ripple control frequency).

WinPQ mobile
High-end Analysis Software

The purpose of the program is to prepare the archived power quality measurements and fault events from all PQ Boxes for the viewer and present them appropriately on the screen of the PC.
