IL19006

The IL19006 Three Phase Power/Energy metering integrated circuit generates a pulse rate output, the frequency of which is proportional to the absolute power consumption. The IL19006 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. The output of this universal three phase power/energy metering integrated circuit, is ideally suited for applications such as residential and industrial energy metering and control.

The IL19006 Three Phase Power/Energy metering integrated circuit is a CMOS mixed signal Analog/Digital integrated circuit, which performs three phase 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 3-phase power and energy measurement such as 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 IL19006 generates pulses, the frequency of which is proportional to the power consumption. Two frequency outputs (FOUT1 and FOUT2) are available. The pulse rate follows the instantaneous power measured.
