ماژول توان سنج CS5460A
مبدلی است که شامل دو مبدل آنالوگ به دیجیتال ΔΣ (ADC)، محاسبه گر توان با سرعت بالا و یک رابط سریال مبدل به دیجیتال با درجه یکپارچگی بالا است.
این ماژول می تواند اندازه گیری و محاسبه دقیق انرژی فعال، توان لحظه ای، IRMS و VRMS انجام دهد.
CS5460A جریان را با استفاده از یک شنت یا ترانسفورماتور کم هزینه اندازه گیری می کند و ولتاژ با یک مقاومت تقسیم کننده ولتاژ یا یک ترانسفورماتور ولتاژ اندازه گیری می شود.
CS5460A با میکروکنترلر برای ارتباط با پورت سریال دو جهته، ورودی پالس تراشه فرکانس متناسب با انرژی فعال است.
Description:
The CS5460A is a converter that contains two ΔΣ 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.
