The Pure BlackBox, an advanced Class A power quality analyzer embedded with PQZIP Technology, is an easy to use plug and play device that continuously records all power quality parameters without thresholds?settings or recording configuration. The device is availiable in 2 versions: Single Phase, 3-Phase

Handy & Ready

When using the Pure BlackBox, any installation errors such as a wrong phase order can be fixed
during post-processing. The Pure BlackBox includes a ride through super capacitors technology to
enable continuous recording during short supply interruptions.

Power quality post recording processing and analysis are available using the free SCADA Sapphire
Express Edition software. Use it via drag and drop of recorded data for immediate analysis,
PQ trending, events and reports.

Recorded information are saved in a non-volatile SD card which can be accessed as a
standard external memory either via the device USB slot connected to a PC, or by inserting the
SD card in a reader connected to a PC.
