7.1.3 SWITCH module
The Switch module realizes a "solid state" switch (MOSFET) device for the distribution of the
power necessary for the proper working of all the modules of the ECOS-D RBS. In particular
its primary task is to distribute the 12 Vdc nominal voltage (Master voltage) and 7 Vdc
nominal voltage (Slave voltage).
The 7 Vdc Slave voltage is used by all the other modules to power their logic. It is generated
by the switch module for direct conversion from the 12 Vdc Master voltage.
The switch module provides:
• ON / OFF of all the modules on the same RBS
• Protection against Extra Current (short circuit or overload > 22 A ± 5%)
• Protection against Extra voltage (maximum input voltage equal to 30 Vdc ± 5%)
• Protection against voltages outside the guaranteed operating range [10.8 ÷ 15.6 Vdc].
• Protection against reverse polarity input voltage.
• Protection against over temperature inside the module itself (≥ 100 ° C ± 1%).
The front panel is provided with bi-color leds to help in troubleshooting the system. The table below
describes the meaning of the leds:
