For the protection of USB signals, our product offers native non-bridging USB signal access, ensuring a simple level design starting from the bus and drive to avoid jitter. The hardware layer strictly follows design specifications for differential traces, passing industrial-level EMI tests. The built-in power supply is directly connected to the power source, completely isolating the USB bus power to prevent interference from the motherboard and other electrical equipment.

Our multi-band, progressive times, and ultimate power filter design provide high stability and high-purity current. With power dynamic compensation technology, large dynamic automatic compensation is provided, ensuring constant ripple of less than 1Hz. The product features multi-mode power input seamless switching and intelligent protection design.

For USB-powered security, the device includes internal and external self-powered identification, automatic switching, and self-protection.
