摘要:
The present invention is directed to an electrical wiring device that includes an AC power supply control circuit, an isolation interface circuit and a low voltage printed circuit board (PCB) assembly. The low voltage PCB assembly includes a universal serial bus (USB) charging interface circuit configured to convert the modulated power signal into a low voltage direct current (DC) charging signal. The at least one low voltage PCB assembly includes at least one USB socket coupled to the USB charging interface circuit and accessible via the at least one USB aperture formed in the front cover member. The USB charging interface circuit is configured to provide the low voltage DC charging signal to at least one device-under-charge at a maximum predetermined charging current.
