Event power planning
UPS for AV control and signal: load, runtime and topology
A UPS can support continuity for AV control and signal-processing equipment. Define the function first: keeping a processor powered does not keep an image on screen if the display itself loses power.
Define the scope and continuity goal
- List processors, playback, console, networking and accessories needed for the function; record W and VA where available.
- State the required duration and whether the goal is riding through an interruption or allowing orderly shutdown.
- Collect input/output voltage and frequency, connectors, startup, environment and load tolerance for interruptions.
Compare capacity, runtime and operating mode
Check both the exact UPS’s W and VA limits. Use its runtime curve for the proposed load and battery configuration; VA does not specify minutes.
Compare standby, line-interactive and online double-conversion against documented regulation and transfer behavior. Review bypass and economy modes too: a topology name does not guarantee continuity in every state.
Complete the proposal
Request the model and regional variant, battery configuration, condition, runtime assumptions, monitoring and a provider-led verification plan. Do not test by cutting venue supplies. A UPS does not add capacity to its input circuit or replace that circuit’s protection.
Planning questions
Should I back up only the playback computer?
Review the whole required chain, including networking and processing. One unprotected dependency can interrupt the function.
Does an old battery still meet the published curve?
Do not assume so. Condition, temperature and load matter; request assessment of the proposed assembly.
Do dual power supplies automatically provide redundancy?
No. Document their sources and common dependencies, following equipment and provider documentation.
Sources and scope
Technical reference documentation. Venue staff and a qualified professional review its application to the actual installation.
Before finalizing the supply, confirm venue and local authority requirements in the United States, or utility and local requirements for an event in Argentina. Confirm the actual site’s electrical configuration regardless of this guide’s language.
