AT5ZN Series Intelligent Power-Specific Meter

Name: AT5ZN Series Intelligent Power-Specific Meter
Brand: MY SHOP

Employing a "two-in-one" technology that integrates a Digital Signal Processing (DSP) chip with an embedded microcontroller, we have independently developed the AT10F003 embedded microcontroller. This design not only simplifies the microcontroller architecture and reduces the need for external components but also ensures precise and stable measurement—thereby meeting the practical measurement and display requirements of power supply manufacturers (e.g., displaying "220" for input voltages ranging from 200 to 240).
