Principle:
Some equalizers are adjusted manually, the 5 pins in the middle of the module are 24V DC power supply, and the AC60V power supply is transmitted together with the TV signal from the coaxial cable (insert AC60V power supply at the front end or in the middle of the main line). AC60V enters the power transformer through the input terminal through the inductance line, becomes greater than 24V AC, and is sent to the stabilized three-terminal "7824" through rectification and filtering to become a stable 24V DC supply module.
Use:
The main function of the cable TV amplifier is to compensate the attenuation caused by the cable TV signal during cable transmission, so that the signal can be transmitted stably, with high quality, and over a long distance. It should also have the effect of balancing the curve in the band.
