panel mounting power analyser according IEC 61000-4-30 class S
The network analyzer RPM85U/RPM85S for accurate monitoring of main electrical parameters in three phase or single phase networks.
The instrument measures continuous voltage and current according to the norm EN61000-4-30 class S. Thanks to precise measurement
and a high sampling rate. It is also ideal for particular measuring points in electrical energy monitoring systems. The communication interface
RS485 with Modbus RTU protocol predefine RPM80/RPM85S can be used as measure point in SCADA system.

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.
