2.2. Protection
2.2.1. Power Supply
2.2.1.1. GL6100 – UART Version
The GL6100 is protected against voltage over +32V. When the input voltage (Vin) exceeds the limit,
the supply voltage is disconnected to protect the internal electronic components from overvoltage.
Note: An 800mA/250V fuse is directly bonded on the Adaptive cable of GL6100. The fuse model is FSD
800mA/250V FAST-ACTING.
