metering
◆Provide three ∑ - △ ADCs
◆Active energy error is less than 0.1% within the dynamic range of 8000:1, supporting the requirements of IEC62053-22:2003 standard
◆Reactive power error is less than 0.1% within the dynamic range of 8000:1, supporting the requirements of IEC62053-23:2003 standard
◆Provide effective value measurement for two currents and one voltage, with an effective value error of less than 0.1% within a dynamic range of 1000:1
◆ Provide a pulse frequency generator that can be used to accumulate and integrate electrical energy for user-defined power
◆ Provide instantaneous sampling values for three ADCs
◆ Adjustable stealth threshold
◆Provide reverse power indication
◆ Provide voltage channel frequency measurement
◆ Provide zero crossing detection for voltage channels
◆ Provide reference benchmark monitoring function
software regulating meter
◆ The electric meter constant (HFConstant) is adjustable
◆ Provide gain and phase correction
◆ Provide offset correction for active, reactive, and effective values
◆ Provide small signal calibration acceleration function
◆ Provide automatic verification function for configuration parameters
Provide SPI/UART interface
Equipped with power monitoring function
Equipped with timed freezing function for electric energy registers
The RX input pin of UART also has pin reset function
RN8209D+5V/3.3V power supply, typical power consumption value is 15mW@5V The 8mW@3.3V
Built in 1.25V ± 1% reference voltage, typical temperature coefficient of 5ppm/℃, maximum 15ppm/℃
Adopting SOP24 green packaging
◆It can measure active power, reactive power, active energy, and reactive energy, and provide two independent active power and effective value, voltage effective value, line frequency, zero crossing interruption, etc. at the same time, which can achieve flexible anti-theft solutions.
◆Support all digital gain, phase, and offset correction. The active power pulse is output from the PF pin, and the reactive power pulse/user-defined power pulse frequency is output from the QF pin.
◆Provide serial interfaces SPI and UART for easy communication with external MCUs.
◆The internal power monitoring circuit can ensure the reliable operation of the chip during power on and off.
