DESCRIPTION  
The SAMES SA2002E is an enhancement of the SA9602E, as  
the circuit contains the oscillator on chip.  
This innovative universal single-phase power/energy metering  
integrated circuit is ideally suited for energy calculations in  
applications such as residential municipal metering and factory  
energy metering and control.  
The SAMES SA2002E single phase uni-directional  
power/energy metering integrated circuit generates a pulse  
rate output with a frequency proportional to the power  
consumption.  
The SA2002E integrated circuit is available in 8, 14 and 20 pin  
dual-in-line plastic (DIP) as well as 16 and 20 pin small outline  
(SOIC) package types.  
The SA2002E performs a calculation for active power. The  
method of calculation takes the power factor into account.  
Energy consumption can be determined by the power  
measurement being integrated over time.
