Three Simple Steps to Take Part in the PQ Box Trade-in Promotion
Participation is simple and straightforward
- You send your order (quantity and desired A. Eberle PQ-Box models) to your sales contact in your region. Please mention in your order that you take part in the PQ-Box Trade-In Promotion. If you do not know your sales contact in you region yet, please contact us at sales@a-eberle.de so that we can assist you.
- For the sake of the environment, we would like to avoid old devices being sent to us. To take part in the PQ-Box Trade-In Promotion campaign, please send the following photos together with your order to your sales contact:
- A photo as proof of the definite destruction of the old device (e.g. destroyed display, cut-off measuring cables, hole/drill through device)
- A photo of the type plate of the old device/s
You can trade-in one old device per order of a PQ-Box 150/200/300. If you order several PQ Boxes and would like to trade-in several old devices, please send both photo proofs (proof of destruction + photo of type plate) for each old device you want to trade-in.
- The discount will be deducted from your order. You will receive the invoice for your order with the already reduced price from your sales contact.
If you have any questions about the PQ-Box Trade-In Promotion or other enquiries, feel free to contact us via email at sales@a-eberle.de.
10 Reasons for Upgrading to the Latest Measurement Technology by A. Eberle
01. Higher Sampling Rate of the Power Quality Analyser – Interference Search in Frequency Ranges up to 170 kHz
New power electronic consumers and energy generators cause interference in the grid in ever higher frequency ranges. The switching frequency of these consumers and generators is power-dependent. In the >30 kW to MW range, the clock frequency is approx. 2.5 kHz to 8 kHz. Up to approx. 30 kW output, the clock frequency is considerably higher. For example, the clock frequency of solar inverters is between 16 kHz and 18 kHz, charging stations for electric vehicles usually clock between 10 kHz and 80 kHz. However, a power quality analyser must sample at least twice as high as the frequency you want to record.

![](https://www.a-eberle.de/wp-content/uploads/2024/07/a-eberle-pq-200-10-gruende-01-2.png)
As a result, mains interference in the 2 kHz to 150 kHz range is constantly increasing in our grids due to the increased use of power electronics. Power quality standards for public grids already provide limit values up to 150 kHz. For example in the international standard IEC 61000-2-2 for low voltage grids.
![](https://www.a-eberle.de/wp-content/uploads/2024/07/a-eberle-pq-200-10-gruende-01-3.png)
02. Standard-Compliant Measurement According to IEC 61000-4-7 in the Frequency Range 2 kHz to 9 kHz
The frequency range of the tolerance levels has been extended upwards in many of today’s standards. For example, many user guidelines for the connection of customer installations in the low, medium and high-voltage networks already contain limit values up to 9 kHz for voltages and currents. PQ-Boxes of the newest generation can supply these measured values in compliance with the given standards. With the current version of the power quality analysis software WinPQ mobil, you as a user can easily create a finished measurement report with the help of pre-installed power quality report templates in conformity with the latest standards.

03. Modifications to IEC 61000-4-30
The scope of the IEC 61000-4-30 measuring device standard has also been greatly expanded. The PQ-Box 100 and old devices from other manufacturers were still developed in accordance to an older Edition of the standard, while the new generation of devices (PQ-Box 150/200/300) already fulfils the latest Edition at 100% for Class A reference measuring devices. This means your device is well prepared for the future.
04. Wider Selection of Measured Values
While the PQ-Box 100 was already able to record over 2,000 different measured values in parallel and without gaps, the latest generation of devices (PQ-Box 150/200/300) calculate more than 5,000 measured values. Active, reactive power or the phase angle and direction of all harmonics – to name just some examples – or the new important frequency range of supraharmonics up to 200kHz. Old devices from other manufacturers, such as the PQ-Box 100, are currently unable to detect a large number of interference phenomena in each measurement parallel.
05. WLAN interface
All devices of the new generation of the PQ-Box have a WLAN interface build in. It is now possible to operate the measuring devices wirelessly via a PC or smartphone. For example, a PQ-Box 150/200/300 can be operated behind a locked door or outdoors on a mast station without having to establish a cable connection.
06. Technical Data of the Devices Has Been Improved
- Battery: PQ-Box 100: approx. 30 seconds vs. PQ-Box 150 (as an example of the new generation of devices): 4 hours. The battery life serves as a backup for bridging power failures and supply interruptions.
- Memory: The memory size for measurement data has also been expanded to 4 GB or 8 GB (optional expansion up to 32 GB is easily possible).
- Display: In the PQ-Box 150/200/300, a graphic colour display replaces the monochrome display used in the PQ-Box 100 or old devices from other manufacturers. For example, a vector diagram or an oscilloscope display can be shown on the display. This shows you as the user possible connection errors of the PQ-Box simply and clearly. Device parameterisation via the larger display and the operating buttons is also simpler and more user-friendly than with a PQ-Box 100 or old devices from previous device generations.
07. TCP/IP Interface
Do you want to check remotely what your PQ measurement is doing? Have enough events already occurred? Can I remove the measuring device at the measuring point?
With the PQ-Box 150/200/300, this is possible via a 3G/4G wireless modem, which is connected via the TCP/IP interface of the network analyser.
08. PQ-Box App
The PQ-Box App enables wireless access to your PQ-Box via WLAN with visualization and display of various live measurement data, including basic parameterization of the device. This comes in addition to an overview of the online data, the recorders and events, power and energy, pointer diagram, oscilloscope view and harmonics of the PQ-Box measurement data. The intuitive operation guarantees a simple and mobile operation of your PQ-Box.

09. Flexible AUX Input or a 5th Power Input
A flexibly parameterisable additional AUX input expands the application possibilities of PQ-Box 150/200/300 enormously. For example, a temperature sensor can be connected to each PQ-Box 200 and PQ-Box 300 in order to measure the temperature in the switch cabinet or on a transformer in parallel with the power quality measurement. The application could also require the measurement of a residual current on an RCD or parallel detection of a PE conductor current on earthing. Of course, you can also set a trigger threshold on the 5th measurement input or record events or faults with the fast recording possibilities.

10. Measure Fast Switching Transients
Fast switching transients are not uncommon in industrial applications. In order to be able to record these extremely fast events, a high sampling frequency is required, coupled with a very large measuring range. Our PQ-Box 200 is specialised for this and samples signals with 4 MHz.
