New version of Ster PMU handheld unit is now available with a slot
for Micro SD flash memory cards. Using a 32Gb flash
card, each unit can store 3-phase synchrophasor measurements (U/I/f), at grid frequency, during a period of over 4 months.
This allows deployment scenarios with no GPRS connection to the server at all, or configurations where data is sent less often
to the server, and manually retrieved by downloading the SD card contents directly to a PC.

Device is fully functional and ready for measurement only a couple of minutes after it has been powered on, while the larger flash
size means that device can be autonomous during blackout conditions even longer (more than 4 hours operating on batteries).
