The device features onboard unibody power supply isolation, delivering a stable isolated voltage without requiring an additional power source. To protect against electrical disruptions, the device is equipped with a transient voltage suppressor (TVS) to effectively manage surges and spike voltages. It also incorporates a self-recovery fuse and protection diodes, which ensure stable current and voltage outputs while providing over-current and over-voltage protection, thereby enhancing shock resistance. The fully automatic transceiver circuit allows the USB port to communicate stably with different interfaces without interference.
