PM9604/5AP

THREE PHASE POWER/ENERGY METERING MODULE

FOR SPI BUS AND PULSE OUTPUT DEVICES

FEATURES

■

Uses current transformers for current

sensing

■

Module used for both SA9604A and

SA9605A evaluation

Meets the accuracy requirements for

Class 1 AC Watt hour meters

■

Protection against ESD

Unused connection pads allows the

module to be customised

Operates over a wide temperature

range

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.
