CS5460A Serial Single-Phase Bi-Directional Power Energy Metering ADC Module

CS5460A Single phase Bi-directional Power Module

CS5460A Single phase Bi-directional Power Module
The CS5460A is a converter that contains two ?? analog-to-digital converters (ADC), high-speed power calculation and a serial interface To-digital converter with a high degree of integration. It can be precise Measurement and calculation of active energy, instantaneous power, IRMS and VRMS,For the development of single-phase 2-wire or 3-wire meter. CS5460A The current can be measured using a low-cost shunt or transformer Voltage is measured with a voltage divider resistor or a voltage transformer. CS5460A With the microcontroller to communicate with the bi-directional serial port, the chip pulse input The frequency is proportional to the active energy. CS5460A is convenient On-chip AC / DC system calibration.The “bootstrap” feature allows the CS5460A to work independently, After the system power automatically initialized. In the self-boot mode.
The CS5460A reads the calibration number from an external EEPROM According to the start instruction.
The CS5460A operates when using this mode When no additional micro-controller, so when the meter for large quantities Residential energy measurement, can reduce the cost of the meter.
