Signal secondary protection
Serial port protector is a plug-in adapter with protection circuit, which is used to protect signal system and equipment, and can be used in high transmission occasions. For example, the host and server protecting the port are installed in front of the serial port. The rated voltage is 8V and 12V, the maximum discharge current is 15ka, and the data transmission rate is 1mbit / s. For fine protection, the rated voltage is 12V DC and the rated discharge current is 100A (8 ~ 20 A) μ s) The data transmission rate is 1mbit / s.
Coaxial cable signal protector is used to protect 75 Ω~ ninety-three Ω The maximum amplified current is 20 Ka (8-20 KA) μ s) The data transmission rate is 16mbit / s. The over-voltage protector of antenna feeder (cable TV line) of broadcasting satellite is used to protect 75 kV Ω System equipment, such as antenna amplifier, broadcast satellite receiving system, etc. The maximum discharge current is 3.5 Ka (8-20 MA) μ s) The frequency range is 4-2050mhz.
