What it represents
An AC/DC power supply converts a documented AC input to a DC output for control or auxiliary circuits. Its input protection, DC common and any PE connection are shown separately.
How to read it
- Identify the DC output polarity and any intentional connection to earth.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- State AC input range
- State DC output rating
- Show input protection and PE
A distinction that matters
A regulated power supply includes functions beyond a bridge rectifier alone.
