7. Main Board description
7.1. Board Layout
Figure 7-1
As shown in
Beside these four areas, there are the input connector on the main board and the two connectors to the
daughter board.
7.2. Power Supplies
The Power Supply input connector is a single input to supply the whole PTC. The Input supply requires a
minimum of 24 volts and can tolerate a maximum of 48 volts. It is not recommended to use a higher
voltage than needed for the application. There’s an internal fuse (on the main board) of 1 A in order to
avoid damage when improperly used. The connected supply should provide a minimum current of 1.5 A
with peak capacity to source 10A.
The external Supply is the source to create all the internal requirements. Internal voltages are created on
the main board by using the input voltage from the external supply.
