QNA-P Portable Power Analyzer      

Product Description

The QNA-P enclosure has an IP 67 degree of protection, which guarantees its robustness to strong impacts. The QNA-P analyzer has been tailor-made with clips and it has a wide range of flexible (LV measurements) and rigid clips (LV and MV Measurements). The internal switches can be adapted to any type of network (3/4 wires), with the use of its rigid (CP type) and flexible (C-FLEX type) clips.
 

• The QNA-P portable analyzer is highly versatile and can combine rigid and flexible nucleus clips. Its robustness makes it ideal for the intake of measurements in places subject to severe weather conditions.
• The unit has been specially designed for the execution of audits and revisions, since it has been certified as Class A, in compliance with the IEC-61000-4-30 Standard, so that the measurements taken can be used for any type of verification; a pattern element is used during the intake process.
• The internal GSM type can also be used to download the information remotely and draft a report with the data, even before removing the analyzer, which avoids the need of travelling to the installations.
