PQ-Box 200 - The Mobile Power Quality Meter for Experts
For rapid root-cause analysis of grid disturbances and switching transients in electrical networks.
For fast, structured investigation of short-term disturbances and switching-related events in grids and networks. It provides reliable measurement data for decisions, evidence and consistent incident handling.
Typical Application:
- Clarifying sudden outages or malfunctions following switching operations
- Pinpointing short-term disturbances with an unclear trigger during operation
- Assessing anomalies at in-feeds, outgoing feeders or critical loads in the network
- Documenting events for internal clarification and discussions with third parties
This Device Is Suitable If:
- You need to capture and attribute short-duration events unambiguously
- You want to substantiate recurring issues with defensible evidence
- You require measurement data to agree actions, approvals or evidence internally or externally
- You need a time-limited analysis directly at the affected point in the grid or network
Rapidly Locate the Causes of Network Faults
PQ-Box 200
The mobile power quality meter PQ-Box 200 has been fitted with a wide range of triggering capabilities in order to rapidly locate the causes of network faults. 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. This means the device offers everything power quality experts need.

Record Rapid Switching Transients at a Rate of 4 mHz
The mobile power quality meter PQ-Box 200 has a sampling rate of 4 MHz for recording rapid switching transients. The measurement range for transients is +/- 5,000V. Voltage and current harmonics are recorded up to 20 kHz. The device is highly accurate and has a 24-bit input converter.
WLAN Interface for Cableless Communication With the Software & App
In addition to a USB and ethernet interface, the data recorded by the PQ-Box 200 can be transferred to the evaluation PC via a fast WLAN interface. 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 200.
All the Standards and Protocols Upheld – Making Our Products Fit for the Future
The mobile power quality meter PQ-Box 200 creates an automatic standard assessment and event record to:
- EN 50160
- 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. 4 Class A
- IEC 61000-4-7
- IEC 61000-4-15
Simple Menu Navigation and Intuitive Operation of the Measuring Device
When designing the menu navigation of our mobile network analyzers, we focused on enabling particularly user-friendly and intuitive navigation and thus operation of the measuring device. This means that you as a user can quickly find your way around the device when using the PQ-Box and concentrate on the essentials: the measurement. The user interface of the PQ-Box 150 is identical to that of the PQ-Box 200 and PQ-Box 300 models - also from the PQ-Box family from "A. Eberle".
Standard Accessories & Device Installation – How Your PQ Box Arrives
- PQ mains analyser »PQ-Box 200«
- USB cable
- 4mm safety sockets incl. inserts for worldwide sockets
