PQube provides at least 150VDC isolation to Earth (eliminates ground loops).
Optional Plug-in Ethernet Module
Standard RJ-45 socket (wired Ethernet).
Sends emails after every event with data attached; user request real-time meters via e-mail, PQube
firmware upgrade via email, change PQube setup via email, incoming e-mail filters. Includes GIF graphs,
CSV spreadsheet files, PQDIF, HTML and XML summaries.
Real-time meters. All events, trends and statistics recordings. Includes GIF graphs, CSV spreadsheet
files, PQDIF, HTML and XML summaries.
Real-time meters with update rate of approximately 1 second. Event/trend-statistics counters can be
used for triggering downloads via FTP or web server.
File Transfer Protocol. Transfers files from PQube SD card to and from any computer. Limit: one
simultaneous connection.
Simple Network Time Protocol for synchronizing PQube real-time clock to UTC. (2 second absolute -
UTC referenced).
Typical ±30 seconds/yr. Temperature compensated. ±120 seconds/yr. max drift
Optional SNTP (Requires ETH1)
±2 seconds absolute, UTC time.
