LORDWORLD USB RS485 Converter CH343 SP485 1.2km

SKU CH-QVNK-56F0M

Converts USB to RS485 for 1.2 km industrial links using CH343 and SP485 chips with TVS surge protection and resettable fuse

  • Real-time status monitoring via three onboard indicator LEDs
  • Reliable data transfer with CH343G and SP485EEN chips
  • Circuit protection from surges using onboard TVS suppressor
  • Stable power delivery through resettable fuse and diodes
  • Extended reach up to 1.2 km transmission distance

Industrial RS485 Converter Module

The LORDWORLD USB to RS485 bidirectional converter module uses an original CH343G and SP485EEN chipset for industrial communication. It provides a reliable interface for connecting RS485 devices to a computer via USB. Three onboard LEDs indicate power and transceiver status for easy monitoring. The module is designed for fast, stable data exchange in demanding environments.

Transmission Distance and Protection Limits

The converter supports a maximum transmission distance of 1.2km under suitable cabling conditions. Onboard TVS diodes suppress surge voltage and transient spikes, offering lightningproof and anti-electrostatic defence. A resettable fuse and protection diodes maintain stable current and voltage output during over-current or over-voltage events. These features protect the module and connected equipment from electrical damage.

Host Compatibility and Wiring Checks

Verify that your host system provides a standard USB port and supports the CH343G driver for proper enumeration. Confirm the RS485 bus wiring uses twisted-pair cable rated for the required distance and noise environment. Ensure the bus termination and biasing resistors match your network topology. Check that the module's protection features meet the specific surge levels present in your installation.

商品問答

What does the 1.2 km transmission distance mean in a real installation?

The 1.2 km figure is the maximum rated range under ideal conditions; actual distance depends on cable quality, baud rate, noise environment and proper termination.

Which USB-to-serial chip and RS-485 transceiver are on the board?

The module uses an original CH343G USB-to-serial controller paired with an SP485EEN RS-485 transceiver for bidirectional conversion.

What protection features are built into the converter?

Onboard TVS diodes suppress surge and transient spikes, while a resettable fuse and protection diodes provide over-current and over-voltage protection.
