V9103
Feature
1. Communication
- Communicating with the main processor via UART ports, to set parameters for energy metering, to read energy metering data, and to configure the work status of the chip;
- Communicating devices via IR modulators, for example, IR reading;
2. Capable of constructing full-wave and fundamental meters, supplying data as follows:
- The active energy, reactive energy, fundamental active energy, and fundamental reactive energy of every phase and all three phases, with error less than 0.1% within the dynamic range of 2000:1;
- The instantaneous and calibrated active power, reactive power, fundamental active power, and fundamental reactive power on each phase and on the overall system;
- The active power, reactive power, fundamental active power, and fundamental reactive power on each phase and on the overall system, per second or per minute;
- Voltage and current RMS values of every phase, instantaneous RMS, RMS per second, and RMS per minute;
- Line frequency and phase on each phase;
- Instantaneous and calibrated apparent power on each phase;
- Power factor angle on each phase;
- Active and reactive energy CF outputs.
3. Voltage Monitoring
- Power-down monitoring circuit, to alarm when power-down is detected, and to store the data automatically;
- To measure battery voltage.
4. RTC
- Providing calendar over the range of 2000~2099;
- Compensating temperature and crystal frequency internally, with high accuracy of 5ppm;
5. EEPROM port, to store significant data automatically;
6. Special status output I/O ports, for querying the status of the chip.
