Three Phase Bidirectional Power/Energy
Metering IC with Instantaneous Pulse Output
SA2005F
sames
FEATURES
n Functionally compatible with the SA9105F with reduced
external components
n Performs bidirectional one, two or three phase power and
energy measurement
n Meets the IEC 521/1036 Specification requirements for
Class 1 AC Watt hour meters
DESCRIPTION
The SAMES SA2005F is an enhancement of the SA9105F. A
precision oscillator and the loop capacitors are integrated on
chip.
The SAMES SA2005F three phase bidirectional power/energy
metering integrated circuit generates pulse rate outputs for
positive and negative energy directions. The frequency of the
pulses is proportional to the measured power consumption.
The SA2005F performs active power calculation.
The method of calculation takes the power factor into account.
n Operates over a wide temperature range
n Uses current transformers for current sensing
n Easily adaptable to different signal levels
n Precision voltage reference on chip
n Precision oscillator on chip.
n Protected against ESD
Energy consumption is determined by integrating the power
measurement over time.
This innovate universal three phase power/energy metering
integrated circuit is ideally suited for applications such as
residential and industrial energy metering and control.
The SA2005F integrated circuit is available in 20 pin dual-in-
line plastic (DIP-20), and 20 pin small outline (SOIC-20)
package types.

VSS Negative Supply voltage.
IVN1, IVN2, IVN3 The current into the A/D converter should be set at 14µARMS at nominal mains
voltage. The voltage sense input saturates at an input current of ±25µA peak.
Inputs from current sensors. The shunt resistor voltage from each channel is
IIN1, IIP1, IIN2, IIP2,
IIN3, IIP3
converted to a current of 16µARMS at rated conditions. The current sense input
saturates at an input current of ±25µA peak.
VREF
This pin provides the connection for the reference current setting resistor.
A 24kW resistor connected to VSS sets the optimum operating condition.
TCLK, TEST
Test inputs. For normal operation these pins must be connected to VSS.
FOUT
Pulse rate output. The pulse frequency is proportional to the sum of the power
measured on all three phases. The pulse format also indicates the direction of
energy flow.
DIR Direction output. This output indicates the direction of energy flow.
PGM0, PGM1
FOUT Pulse format Select. These inputs define the FOUT pulse width
and format.
