Blocks diagram
The electronic design shows the presence of two main structures:
(•) a CPU guarantees the correct operation of all the basic electronics and performs the voltage and current
measurement
(•) the power components. The isolated converter is powered via one or both pairs of input terminals
The following is a schematic detail of the LiteSync design structure.
The power inputs, connectable through two redundant connectors, they have the negative pole interconnected and no
conversion is made to the applied voltage, so it will be the same voltage that comes out of the PoE port.
In this way it is possible to connect several voltages simultaneously, for example:
Input power 1
Input power 2
