AT8ZN Series Intelligent Meters for Welding Machines

Name: AT8ZN Series Intelligent Meters for Welding Machines
Brand: MY SHOP

Leveraging a "two-in-one" technology that integrates Digital Signal Processing (DSP) chips with embedded microcontrollers, we have independently developed the AT10F003 embedded MCU. This innovation not only simplifies the microcontroller design and reduces the need for external components but also ensures precise and stable measurement capabilities. The AT8ZN series thus offers exceptional value, catering to the diverse requirements of inverter welding machine manufacturers and establishing itself as the most competitive product line in its class. Furthermore, the series features a variety of form factors across the entire range, providing developers with a wide array of options for product application and integration.
