A DC/DC converter changes a documented DC input into another DC output.

## What it represents

A DC/DC converter changes a documented DC input into another DC output. Isolation, regulation and polarity depend on the selected model and must not be inferred from the conversion label.

## How to read it

- Check whether input and output commons are connected internally.
- 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 input/output ratings
- Identify isolation specification
- Show input/output polarity

## Important distinction

A DC/DC conversion function does not automatically provide galvanic isolation.

## Facts

- Drawing role: Energy conversion
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
