24 bit analog-to-digital converter GX131E04 replaces ADS131E04 for application in single-phase and multi-phase power systems

The power system is the core of energy transmission and distribution, and its stable operation relies on precise monitoring and control of parameters such as voltage, current, and power. Whether it is a single-phase system for residential electricity or a three-phase system for industrial production, real-time monitoring of the dynamic changes in electrical parameters is necessary. Single phase systems require precise measurement of energy consumption, while three-phase systems require monitoring of imbalance and harmonic distortion to avoid equipment damage.

GXSC is a 4-channel synchronous sampling 24 bit analog-to-digital converter GX131E04. Its high precision, high synchronization, strong anti-interference and other characteristics make it an ideal choice for monitoring single-phase and multi-phase power systems, providing high-precision monitoring solutions for power metering, state assessment and protection control.

The core requirements of single-phase systems are high-precision energy measurement and safety protection, while the requirements of three-phase systems are more complex, requiring multi parameter synchronous monitoring and quality evaluation. The dynamic range of GX131E04 is 120dB at 1kSPS, crosstalk is -125dB, and total harmonic distortion is -108dB at 50Hz and 60Hz, meeting the requirements of measurement accuracy. Its wide dynamic range, expandable data transmission rate, and internal fault detection monitoring meter are very suitable for industrial power monitoring and protection, as well as testing and measurement applications. The high integration and excellent performance of GX131E04 enable the product to greatly reduce size, power consumption, and overall cost.

GX131E04 has a flexible input multiplexer on each channel, which is independently connected to generate signals internally for testing, temperature, and fault detection. Fault detection can be performed internally within the device, which uses an integrated comparator with trigger levels controlled by a digital to analog converter, and can operate at data rates up to 64kSPS.
