UOTEK RS-232 lightning protector

     This lightning surge protector refers to the national standard IEC61643-21:2000 / GB/T18802.21 design. With the development of the national economy, the development of the Internet era is increasingly new, the rapid progress in the development of Internet technology. However, it cannot ignore the existence of this or that problem in the development, safety issues are put in the first place. Daily life, lightning damage to electronic equipment is the most serious, static electricity generated by the threat is also everywhere, in order to the majority of users have a safer use of the environment, to improve the reliability of equipment requirements are increasingly strong.

     Uses: Used for industrial control Internet, RS-232 interface, dedicated lines, automatic control and instrumentation lines, data lines and telephone equipment, fax machines and other equipment protection, but also for the protection of sensors in the current loop, secondary instruments; so that the protected equipment from damage caused by induction overvoltage, operating overvoltage and electrostatic discharge.
