2. Protected signal ground connection
3.4500V surge protection

FL485                        RS485 Surge Protector

 

Introduction  

IEC61000-4-5 and ITU-TK20&K21 are the recognized standards for top quality surge protectors, FL485, rs485 surge protector have high respond speed, low output rudimental voltage, ascendance transfer performance. All have #10 ground screws which must be connected to a solid ground. 

 

Circuit diagram

FL485, rs485 surge protector is designed by the theory of current limited and voltage clamped, discharged to ground. When the data line exist surge, the rs485 surge protector  is induced and worked ,the lightning energy is discharged to ground, and the high surge voltage is clamped to low level, so our devices is protected.
