Three-phase electrical parameter and energy measurement instrument

1、Equipment description

This series of three-phase energy comprehensive meters is a new generation of electrical parameter measurement products by Yidi Electronics Co., Ltd. It is based on a 32-bit Cortex-M3 core ARM chip, supporting up to 72MHz main frequency, with powerful functions, rich peripheral interfaces, providing 16 channels of 12-bit ADC, with a maximum sampling rate of 1Msps. Uses ultra-large-scale integrated circuits internally, reducing size significantly, greatly decreasing fault points, and achieving precision, meticulousness in manufacturing, safety, convenience, and simplicity in use, leading in the industry.

This series of meters features fast testing speed, high measurement accuracy, simple operation, safety, and reliability. No need to change wiring methods, can be used for multiple purposes with one device, or networked with multiple devices.

Widely used in household appliances manufacturers such as washing machines, refrigerators, air conditioners, fans, energy-saving lamps, range hoods, etc., lighting electrical appliance manufacturers, motor, transformer, and other electrical manufacturers. Also suitable as analytical equipment for laboratories, new product development, and quality supervision departments. This series of meters can measure the energy indicators of exported products (110V/60Hz, 220V/50Hz).
