FUNCTIONAL DESCRIPTION:
The ILA19002 Single Phase Bidirectional Power/Energy metering integrated circuit generates
a pulse rate output, the frequency of which is proportional to the power consumption. The
ILA19002 performs the calculations of active power.
The method of calculation takes the power factor into account.
Energy consumption is determined by the power measurement being integrated over time.
This universal single phase bidirectional power/energy metering integrated circuit is ideally
suited for energy calculation in applications such as residential municipal metering and factory
energy metering and control.
The ILA19002 Single Phase Bidirectional Power/Energy metering integrated circuit is a
CMOS mixed signal Analog/Digital integrated circuit, which performs power/energy
calculations over a range of 1000:1, to an overall accuracy of better than Class 1.
The integrated circuit includes all the required functions for 1-phase power and energy
measurement such as two oversampling A/D converters for the voltage and current sense
inputs, power calculation and energy integration. Internal offsets are eliminated through the
use of cancellation procedures.
The ILA19002 Single Phase Bidirectional Power/Energy metering integrated circuit generates
pulses, the frequency of which is proportional to the power consumption. The pulse rate
follows the instantaneous power consumption measured. Direction information is also
provided. A voltage zero crossover signal, relevant to the positive going half cycle, is available
on pin FMO. This signal can be used to synchronise circuit breaker switching.
IC is available in both 14 and 20 pin dual-in-plastic (DIP-14/DIP-20), as well as 20 pin small
outline (SOIC-20) package types.
