Description
This kind of multiswitches is dedicated for small (4-16 outlets) and medium size (17-70 outlets) subscriber systems with distribution of the first SAT intermediate frequency and terrestrial TV signals. The multiswitches have to work inside buildings.
Work safety
The device is powered with 220-240V AC power network. All obligatory precautions for working with dangerous live voltages should be obeyed.
Multiswitch operation
The following voltages occur at inputs of the multiswitch:
- 18VDC at H,lo and H,Hi inputs
- 14VDC at V,lo and V,Hi Inputs
- 12VDC at the input of terrestrial TV. This voltage enables to power a pre-amplifier. In a case no amplifier is being used, the voltage is automatically disconnected.
Unused inputs of multiswitches have to be closed with terminating resistors with blocking capacitors.
