sames
FEATURES
+ Functionally compatible with the SA9602H with reduced
external components
+ Bi-directional power and energy measurement
+ Meets the IEC 521/1036 Specification requirements for
Class 1 AC Watt hour meters
+ Protected against ESD
DESCRIPTION
The SAMES SA2002H is an enhancement of the SA9602H, as
the circuit contains the oscillator on chip.
The SAMES SA2002H single phase bi-directional
power/energy metering integrated circuit generates a pulse
rate output with a frequency proportional to the power
consumption.
The SA2002H 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.
+ Total power consumption rating below 25mW
+ Adaptable to different types of current sensors
+ Operates over a wide temperature range
+ Precision voltage reference on-chip
+ Precision 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 SA2002H 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.
