PM9109BF

MONOCHIP SINGLE PHASE BIDIRECTIONAL

KILOWATT HOUR METERING MODULE

FEATURES

Performs bidirectional energy meter-

ing and includes a 7 digit LCD driver

with announciators

Pulse output for calibration

Total power consumption rating below

600mW

4 externally selectable on-chip tariff

registers

Uses a shunt resistor for current sens-

ing

An additional total energy register

Operates over a wide temperature

range

Meets the accuracy requirements for

Class 1 AC Watt hour meters

Demonstration software included

Optical interface for electronic reading

according to IEC1107 Mode D

DESCRIPTION

The SAMES monochip single phase bidirectional kilowatt hour metering module, the

PM9109BF, provides all the required metering functions including energy measure-

ment, a 7 digit LCD driver, a tariff selection facility, an optical port as well as a pulse

output for calibration purposes.

Energy consumption is determined by the power measurement being integrated over

time.

This method of calculation takes the power factor into account.

This application utilises the SAMES SA9109BFA monochip single phase bidirectional

kilowatt hour metering IC for energy measurement.

As a safety measure, this application shows the current sensor connected to the neutral

line. In practice the live line may be used for current sensing, provided that the supply

connections (MAINS) are reversed on the module.
