What it represents
A DC UPS maintains a documented DC load supply during a specified input interruption using an associated energy store. The drawing identifies normal supply, storage and load paths plus monitoring signals.
How to read it
- Trace the battery or capacitor module separately from the DC load feed.
- 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
- Show normal input
- Show storage connection
- Reference load and autonomy data
A distinction that matters
A DC UPS feeds DC loads; an AC UPS includes a documented AC output path.
