Schematic symbols have been standardized by two different guidelines:
29+ Dc Power Supply Schematic Symbol Pics. Uniterruptable power supply• a ups is a battery back up for a device when the power fails.• the rating plate of an extra low voltage power supply unit (elvpsu) shows various symbols and abbreviations representing ratings, class, insulation, polarity and other electrical safety and emc. This represents the dc power.

Though these names are not approved as standard notations, they are commonly used by most people. It can deliver up to 1.6 a. Voltage regulator protective conductor power source (us) rectifier generator dc generator ac power source dc voltage dc voltage battery ac voltage ac voltage hf ground.
But the definition of what a power supply is doesn't really do justice to what there are many electrical and electronic schematic symbols are used to signify basic electronic or electrical device.
An open source hardware (oshw) benchtop dc power supply designed using open source tools minimum smd size is 0603 to make it feasible to still hand solder. Ac dc configurable power supply chassis. Now that we understand how the schematics work, we can proceed with building the pcb for our smps. This represents the dc power.
