General
Consumption 24V
- The Power Supply Unit can power up to 16 Twin Modulator modules.
- Whenever the demand of power exceeds 4A (max. current for each output), it is necessary to distribute it between the two powering outputs of the PSU.
- The technical characteristics described are defined for a maximum ambient temperature of 45°C (113ºF). Forced ventilation is used for higher temperatures.
Inputs/Outputs/Connections description
The unit (Fig. 1) is provided with:
1. RF input
2. RF output + 2 CH TV (module A and module B)
3. Powering BUS connectors
4. Status LED
5. Control BUS connectors
6. Audio / video input signal connector (module A and module B)
7. Programmer / PC connector
Introduction
The TWIN unit features two A/V inputs (modules A and B) which generate
two independent output channels.
The A/V inputs for each module (A and B) are modulated according to the TV
standard in an IF of 38.9 MHz.
The modulated IF signal is converted to any channel or frequency between 46
and 862 MHz and then, once filtered, it is amplified to achieve the specified
output level.
It is also possible to control the unit via a PC as is explained in User manual.
