DESCRIPTION
This innovative power/energy module allows evaluation of both the SA9604A and
SA9605A, members of the SAMES three phase metering I.C. family.
It is advised that the relevant data sheet for the device under evaluation be read in
conjunction with this Application Note.
The output of this innovative universal three phase power/energy metering circuit is
ideally suited for energy calculations in applications using a 碌-controller (SA9604A and
SA9605A) or mechanical counter (SA9605A).
On the left hand side of the board, next to the 25-way D-type connector, the array of
unused solder pads allow the user to customise the module. This section of the board
may be used to access the opto-coupler isolated output signals. Such components as
counters and LEDs may be added to this area to allow the user evaluation of a design
using the SA9604A or SA9605A.
CARE MUST BE TAKEN WHEN CONNECTING ADDITIONAL COMPONENTS TO
THE BOARD AS DANGEROUS VOLTAGE LEVELS EXIST IN SOME AREAS.
