Success Case: Custom Embedded USB-C Module for Global Retail Display Systems
We are proud to announce the successful delivery of a new custom-designed embedded USB-C charging module, tailored specifically for integration into advanced desktop power systems.
This tailored solution was developed in collaboration with an international client in the consumer electronics retail sector. The module is now being used in smartphone display tables across flagship stores, enabling continuous, secure, and invisible charging for demo devices.
After rigorous development and testing, the module has now been certified by the VDE testing laboratory, confirming full compliance with international safety, EMC, and energy efficiency standards.
The end client, a global consumer electronics brand, sought a discreet yet powerful power supply solution for its flagship mobile phone display tables. The system needed to:
Supply continuous and safe USB-C PD power to multiple smartphones on display.
Fit seamlessly into the slim internal structure of desktop furniture.
Provide thermal and safety protection for long-hour usage in retail environments.
Support global voltage input for multi-market deployment.
To meet these requirements, our engineering team delivered a fully customized USB-C module with the following highlights:
Ultra-thin PCB layout for seamless furniture integration.
Smart Power Management: Single or dual-port USB-C PD output supporting 5V/9V/12V/15V (3A) and 20V (2.25A).
Robust Protection: Over-voltage, over-current, and over-temperature safeguards.
Universal Input: 100–250VAC, 50/60Hz, ready for global deployment.
Compatibility: Fully compatible with the client's modular power architecture.
