CH343G industrial converter with isolation USB RS232 RS485 UART TTL 3.3V 5V

The USB to RS232/RS485/TTL converter is a reliable, high-performance device that provides stable and fast communication between different interfaces. The device is equipped with the original FT232RL or CH343G chip, which guarantees excellent compatibility, stability and speed of data transmission. With built-in power isolation and digital isolation, the converter offers high reliability, low power consumption and strong noise immunity, without the need for an additional power supply for the isolated terminal. The converter has a range of protection features, including a transient voltage suppressor (TVS) that effectively protects against overvoltage and voltage spikes, providing electrostatic discharge (ESD) protection and lightning protection. Built-in self-correcting fuses and protection diodes guarantee stable current and voltage outputs, providing overload protection and improving shock resistance. The converter's aluminium housing with anodised oxidation and sandblasting process is robust and durable, further enhancing the unit's durability in demanding industrial environments. The device is equipped with three LEDs to indicate the status of power and data transmission. High-quality USB-B and RS232 connectors ensure smooth connection and disconnection of cables.
