Powerful Energy Meter Chipset
ADSST-SALEM-3T
FEATURES
High accuracy
Supports IEC 60687/61036 and ANSI C12.1/12.20
Suitable for class0.5 and class0.2 meter
Full four quadrant measurement of parameters
SPI® compatible serial interface
Pulse output with programmable pulse constant as
pulses/kWh or Wh/pulse
Programmable duty cycle for pulse output
chipset can be interfaced to any general-purpose microproces-
sor to develop state of the art tri-vector or polyphase energy
metering solutions with a wide range of basic currents from 1 A
to 30 A. By incorporating a comprehensive data set of parame-
ters, including instantaneous measurements, accumulated
parameters, and harmonic analysis data, the ADSST-SALEM-3T
chipset meets high end energy metering requirements. The abil-
ity to easily configure the chipset for various parameters makes
it a very flexible solution.

transformers is done in software (patent pending) without
having to use any passive components in the circuit for
compensation, thus minimizing variations in accuracy with
temperature and time.
The ADSST-SALEM-3T measures and computes a large num-
ber of parameters essential for high end metering.

GENERAL DESCRIPTION
DataSheet4U.cRoMmS Voltage
The ADSST-SALEM-3T energy meter chipset consists of an
efficient ADSST-218x digital signal processor (DSP), a fast and
accurate 6-channel, 16-bit ADSST-73360LAR sigma-delta ana-
log-to-digital converter (ADC), and metering software. Two
chipset versions are available to support differing ranges of
operating temperature: The ADSST-EM-3040 chipset is rated at
0°C to 70°C for commercial applications, while the ADSST-EM-

The ADC and DSP are interfaced to simultaneously acquire
voltage and current samples on all three phases and to perform
mathematically intensive computations to calculate various
instantaneous parameters and perform harmonic analysis. The
The ADSST-SALEM-3T offers some excellent features that
make the final meter cost-effective and easy to manufacture.
