A power supply board design required.
Board will have an AC input which will be able to work on 115V and 230V mains voltages.
Board will have 6 different isolated 24V DC outputs, these outputs will be able to supply 1A of current typically and 1.2A on burst condition. Also there will be 5V 3A and 3.3V 1A non-isolated outputs.
There will be 2x 12V Lead-Acid battery connection for backup the mains input.
Power supply will be controlled with an integrated microcontroller and will support security functions.
Design will be performed with avoiding obsolete parts and will utilise SMD technology.
In the first stage, detailed system plan needed prior to elecrical design.
