DESCRIPTION
The SAMES SA9102F and SA9102H Single
Phase bidirectional Power/Energy metering
integrated circuits generate pulse rate
outputs for positive and negative energy
directions, the frequency of which is
proportional to the power consumption.
These devices perform the calculation for
active power.
The method of calculation takes the power
factor into account.
Energy consumption is determined by the
power measurement being integrated over
time.
These innovative universal power/energy
metering integrated circuits are ideally suited
for energy calculations in applications such
as electricity dispensing systems (ED's),
residential municipal metering and factory
energy metering and control.
The SA9102F and SA9102H integrated
circuits are available in both 20 pin dual-in-
line plastic (DIP-20), as well as 20 pin small
outline (SOIC-20) package types.

SA9102F/SA9102H
1. Power calculation
In the Application Circuit (Figure 1), the voltage drop across the shunt will be
between 0 and 16mV (0 to 80A through a shunt resistor of 200µ). This voltage is
converted to a current of between 0 and 16µA, by means of resistors R1 and R2.
The current sense input saturates at an input current of ±25µA peak.
For the voltage sensor input, the mains voltage (230VAC) is divided down through
a divider to 14V. The current into the A/D converter input is set at 14µA at nominal
mains voltage, via resistor R4 (1M).
In this configuration, with a mains voltage of 230V and a current of 80A, the output
frequency of the SA9102F and SA9102H power meter chips at FOUT (Pin 12) is
64Hz. In this case 1 pulse will correspond to an energy consumption of 18.4kW/
64Hz = 287.5Ws.
2. Analog Input configuration
The input circuitry of the current and voltage sensor inputs are illustrated below.
These inputs are protected against electrostatic discharge through clamping
diodes.
The feedback loops from the outputs of the amplifiers AI and AV generate virtual
shorts on the signal inputs. Exact duplications of the input currents are generated
for the analog signal processing circuitry.
