PQube3 provides data in several useful formats.

• Various events, trends, and statistics in *.GIF and *.CSV data files

• Provides text, XML, and HTML summary information

• PQDIF file (IEEE standard for electrical quality data files)

Each graph and chart is displayed in two user-selected languages (a total of 35
Displayed as selectable languages*)

• All graphs are created by PQube3, software

without, easily viewed by a browser or image viewer.
Graphs are simply attached as email attachments.

Can be sent to everyone (eg equipment engineer or power supply company)

PQub3 screen web interface.

From here, the user can check the PQube3 status, access and view real-time values, and send commands.

Each PQube3 can be managed by assigning a unique name and location to manage multiple PQube3s.

Internet cloud service that integrates and manages all PQube or PQube3 events in the area

If the individual PQube3 SD card is full of events, it automatically deletes the last month data, or the operator backs up the PQube3 SD card one by one and deletes the data. There is no event to be thrown away by linking with and saving it.

It can enlarge and reduce events like instrument waveforms to investigate and analyze them, and provides EN50160 report writing function, various long-term and short-term trends, and energy usage tracking graphs.
