DESCRIPTION
The SAMES SA2002E is an enhancement of the SA9602E, as
the circuit contains the oscillator on chip.
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 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.
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 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.
