A galvanic isolator is an element used in television installations to neutralise the negative effects of potential differences in the various branches of the network.
• Solves problems caused by potential differences between network segments, network and receivers etc.
• Operating band: 2400 MHz
• Low loss (<1.5 dB up to 1000 MHz)
• Full galvanic isolation (both of signal path and screen
• Breakdown voltage 3000 V for 1 minute test with current leak < 0.7 mA
• Operating band: 2400 MHz
• Low loss (<1.5 dB up to 1000 MHz)
• Full galvanic isolation (both of signal path and screen
• Breakdown voltage 3000 V for 1 minute test with current leak < 0.7 mA
Details
In larger installations, potential differences between individual network segments mean that when unplugging, e.g. splitters or amplifiers, the overvoltages that occur can cause component damage or slight shock. The solution is to use galvanic isolators.
One example is the Signal insulator. It has the advantage of being insulated in both the outer and inner conductor and of being small in size. Attenuation does not exceed 1.5 dB in the entire 5-1000 MHz band. The galvanic isolator should be used both at the entrance of the distribution network to the building and at the distribution of the signal to individual staircases.
In practice, such isolators should be used at the output of each building amplifier. Another application is to isolate the chassis of PC employing TV-tuner from the zero voltage rail of the cable system. This way, a difference of potentials does not harm signal quality, as well as modern sensitive cut-outs will not switch off the power network.
Characteristics of the device: BLUE - attenuation, RED - impedance matching
Example of application - isolation in each staircase
