●  8-ch video surge protector device designed according to
the standard of GB/T18802.21-2004/IEC61643-21:200.                                                          
● The device 's nominal operating voltage is 5V,
max continuous operating voltage is 6V, limiting voltage lower than 20V.                                                                                                            
● It features multi-level protection, high capacity for through-flow,
low limiting voltage,
quick reaction time, less insertion loss.                                                                                                                  
● It adapts to overvoltage protection for security video signal and power,
protecting the device from the damage of induced overvoltage,
switching overvoltage and static discharge.                                                              
●  It's widely used in security monitoring system, environment monitoring system.
