Extremely robust and reliable

The mobile network analyser

The PQ-Box family consists of powerful, portable network and frequency analysers, power measurement devices and transient recorders.

During their development, user-friendliness and practical considerations were the key concern. To quickly locate the cause of network errors, the devices are fitted with a wide range of trigger options.

All mobile network analysers fulfil the high demands of IP65 and can also be installed and used outside. They also have a large operating temperature range of – 20°C to + 60°C.

And they fulfil every requirement of the measurement devices standards IEC61000-4-30 Ed.3, IEC62586-1 and IEC62586-2 Ed.2 for class A devices.

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.

The right box for every frequency

Our mobile analysers

Today’s devices and equipment such as switched-mode power supplies, frequency converters, controlled drives, charging devices for e-mobiles or LED lighting, work internally with high clock frequencies and power to be controlled efficiently. These can lead to both line-bound and field-bound (coupled) influences in the energy grid.

Typical clock frequencies of systems and devices that we have to reckon with in our networks today:

  • 4 kHz to 20 kHz: Frequency converter drive
  • 16 kHz to 22 kHz: Solar inverter (400V)               
  • 2 kHz to 6 kHz: Wind power plant (medium voltage grid)
  • 10 kHz to 80 kHz: E-mobile
  • 8 kHz to 20 kHz: Active grid filter
  • 15 kHz to 25 kHz: UPS systems
  • 20 kHz to 200 kHz: Electronic ballast
  • 30 kHz to 300 kHz: Switching power supplies

The power analysers from A.Eberle have a high bandwidth which is free of aliasing effects up to 170 kHz (PQ Box-300).

These devices can be used to detect the mains feedback in the super-harmonic range of solar inverters, e-mobiles and frequency converters. The IEC61000-2-2 standard already offers compatibility levels for the public grid of up to 150 kHz. These limit values are already stored in our measurement technology.
