RPM95U/RPM95S

panel mounting quality analyser according IEC 61000-4-30 class A

The power quality analyzer RPM95U/RPM95S is a high-end power quality analyzer, able to monitor and record the major power quality parameters.

It provides an accurate measurement, voltage characteristics are monitoring according to EN61000-4-30:2015 Ed.3 Class A specification.

RPM95U/RPM95S is designed to measurement of electrical parameters in LV and MV systems. It is built on 32bit DSP processor that it can provide sufficient processing capabilities for real-time measurement and calculation of all parameters. Continuous sampling of the voltage and current inputs at 66.5 KHz, guarantees the highest accuracy. At the same time it acts as event/fault recorder, capable to store a high number of voltage events and disturbances, frequency variations, inrush current. The RPM95U/RPM95S is the ideal instrument for power quality monitoring according to EN50160 of the incoming energy supply side as well as on the consumer side in order to find and analysis the root cause of network problems.

Data logger and software

Power monitoring software (PCMS) is designed for remote control and management of all Romaz instruments equipped with

communication interface. Standard excel file formats gives the possibility to have a quick view and analysis on all stored data

without any special software. PCMS is provided to perform statistical analysis and generate reports on recorded data according to

EN50160 PQ standard.
