RS232 interface lightning arrester
The RS232 interface type lightning protection device has 25-core, 15-core or 9-core D-type standard joints, can provide accurate over-voltage protection for communication lines of standard or non-standard definition. The series of products are especially suitable for the subtle protection of the corresponding interfaces of the computer systems of the institutions, financial industry, security industry, insurance industry and so on, and further can be used as the surge impulse resistance protection device of a printer interface.
