Televes EuroSwitch 17 Entradas - 24 Saídas
Compactos e eficazes para instalações de grandes dimensões
Product Description
The EuroSwitch 17x17x24 is a compact multiswitch with 17 inputs (one for terrestrial signal and 16 for four satellites and their respective polarities) and 24 user outputs. Its high compactness and advanced electronic design allow for reduced losses in both branching and passage. This characteristic enables a reduction in the number of cascading amplifiers and delivers a more balanced signal among users, even in large collective installations.
With a simple switch, the equipment can be installed as a terminal (in star topology) or in cascade. It also features a second switch that activates TForce technology, automatically adjusting the terrestrial signal and keeping it stable despite reception variations.
Key Features:
- Extra compact in dimensions and weight, even for models with a high number of users.
- Very low derivation and passage losses.
- High shielding (Class A), manufactured from zamak.
- Versatility: switch to alternate between cascade and terminal modes.
- High isolation between inputs and outputs.
- Equipped with TForce technology, the terrestrial output level is automatically adjusted (TERR. AMP. ACTIVE) to the ideal level.
- Two power supply possibilities: via the power supply unit or remotely via the downlead/cascade line.
- Low consumption under normal conditions. Additionally, the ECO mode reduces consumption as the number of users decreases.
- Wide power supply range of 12 to 18V, compatible with most existing systems.
- Current passage between all inputs and cascades.
- Input and output identification by color.
- 100% European design, quality, and manufacturing.

Installation Example (Large Buildings - 4 Satellites)
The LNBs, terrestrial antenna, and the entire cascade are powered by several 3A power supply units (PSUs). The number of power supply units in the system will be calculated based on the total energy consumption of the installation. In the case of using amplifiers, these will be the recommended elements for the placement of the power supply units.
The diagram illustrates a typical installation setup:
- Input: SAT 1, SAT 2, SAT 3, SAT 4, DTT (Terrestrial)
- Multiswitch (MSW 17x17x16): Multiple units are used in cascade.
- Output: TV, STB (Set-Top Box)
- Power Supply Units (PSU): 3A PSUs (Ref. 732802) are used to power the system.
- Configuration: TERR. AMP. (T.Force) = ACTIVE, AUTOLOAD = CASCADE/TERMINAL, TERR. DC = ON.
- Diagram Notation: Arrows indicate the flow of DC power from the PSU.
