Available from Eaton Industries , the QNA 400 Series is a collection of premier electrical power quality analysers.
Power quality analysers measure and record any event that occurs on an electricity system and have been specifically designed to take highly accurate measurements in HV / MV / LV systems. They can be positioned in transformer bays or placed at the service entrance or even at specific distribution points in any company.
QNA 400 Series power quality analysers are compliant with IEC-61000-4- 30 International Standards, which stipulate the measurement methods used by equipment measuring electrical supply. The 400 Series is classified as a class A instrument, under the different classifications in this Standard.
These high quality power analysing loggers are suitable for smaller consumers all the way up to substation and generation consumers. They are available in fixed and portable types as well as dedicated software for remote management of recorded information.
The QNA 400 Series is specially designed for attaching seals to ensure measurement integrity, and features anti-fraud detection which records in the memory the setting changes, loss of voltage and any type of operation carried out on the equipment.
Additionally, passwords are necessary for both writing and reading to protect access to the information contained within the equipment.
