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 µ-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.

7. Circuit Description
The module is supplied from an on-board DC supply derived from the incoming
three phases.
The Application Circuit (Figure 2) details the components required for a three phase
power metering module. Terminated current transformers are used as current
sensors.
The most important external components are:
Terminated current sensors (current transformers) are connected to the current
sensor inputs of the devices through current setting resistors (R8...R13).
The resistor values should be selected for an input current of 16µARMS into the
integrated circuit current sensor inputs at the rated line current.
The values of these resistors are calculated as follows:
Phase 1:
R8 = R9 = (IL1/16µARMS) x R17/2
Phase 2:
R10 = R11= (IL2/16µARMS) x R18/2
Phase 3:
R = R = (I /16µA ) x R /2

Termination resistors of the three current
transformers.
R1A, R1B, R4 and R14 set the current for the phase 1 voltage sense input. R2A + R2B,R5
and R15 set the current Phase 2 and R3A + R3B, R6 and R16 set the current for Phase
3. The values should be selected so that the input current into the voltage sense
input (virtual ground) is set to 14µARMS at nominal line voltage. Capacitors C1, C2
and C3 are for decoupling and phase compensation.
Resistors R7A+ R7B and trimpot T7 defines all on-chip bias currents. R7 is made up
of two resistors which can be connected in parallel using JP7 to allow convertion of
the module between the SA9604A and SA9605A devices.
The SA9604A uses a reference current of 25µA ± 10% and the SA9605A reference
current is 50µA ± 10%. Inserting the jumper will connect R7A and R7B in parallel,
thereby doubling the reference current to an appropriate level. T may be varied for
7
calibration purposes.
XTAL is a colour burst TV crystal (f = 3.5795 MHz) for the oscillator. The oscillator
frequency is divided down to 1.7897 MHz on-chip to supply the digital circuitry and
the A/D converters.
