Prevention is better than a cure
Speak to our teamUPS Selector
Find the right Uniti Power UPS for your equipment. Build your load from the equipment you have, or enter the watts directly, set how long it must keep running during a power cut, and the selector shows the models and battery configurations that meet it, with runtime curves, rack diagrams, side-by-side comparison and a one-click quote request.
Symphony, Echo and Tempo UPS
The selector covers the Symphony and Echo ranges of online double-conversion UPS and the Tempo range of line-interactive UPS, from 850VA to 10kVA. Runtimes are typical figures for new batteries, based on the range brochures and the Tempo datasheet.
| Model | Rating | Format | Runtime at full load | Longest runtime at full load |
|---|---|---|---|---|
| Symphony SPY1500RMi2U | 1500VA / 1500W | 2U rack/tower | 3.3 min | 1 h 05 min with 4 x EBM3618RT2U |
| Symphony SPY3000RMi2U | 3000VA / 3000W | 2U rack/tower | 3.5 min | 1 h 07 min with 4 x EBM7218RT2U |
| Symphony SPY6KiRTB | 6000VA / 6000W | 5U rack/tower | 7.9 min | 1 h 15 min with 5 x EBM2409RT3U |
| Symphony SPY10KiRTB | 10000VA / 10000W | 5U rack/tower | 3.8 min | 37.6 min with 5 x EBM2409RT3U |
| Echo ECH1000RMi2U | 1000VA / 900W | 2U rack | 3.8 min | Internal batteries only |
| Echo ECH2000RMi2U | 2000VA / 1800W | 2U rack | 3.6 min | Internal batteries only |
| Echo ECH3000RMi2UER | 3000VA / 2700W | 2U rack | 3.7 min with 1 x EBM72VRM2U | 26.0 min with 4 x EBM72VRM2U |
| Tempo TMP850IEC | 850VA / 480W | Tower | 1.7 min | Internal batteries only |
| Tempo TMP1200IEC | 1200VA / 600W | Tower | 2.7 min | Internal batteries only |
| Tempo TMP2200IEC | 2200VA / 1200W | Tower | 1.3 min | Internal batteries only |
How to choose a UPS
- Add up the load: total the power draw in watts of everything the UPS will protect. Equipment labels often show a maximum rating that is higher than the actual draw, so use measured or datasheet figures where you have them.
- Allow headroom: the selector recommends a UPS with 20% spare capacity by default, leaving room for start-up peaks and future equipment. You can change this, and allow for growth and battery ageing, in the planning options.
- Decide on runtime: choose how long the equipment must run on battery, whether that is a few minutes for a controlled shutdown or an hour or more to ride through longer outages.
- Check installation: consider rack or tower mounting, plug-in or hardwired connection, and the outlets you need.
UPS selector questions answered
How is runtime calculated?
Runtimes are calculated from the load you enter, each model's battery configuration and the discharge characteristics of its batteries, calibrated to the figures published in the Symphony Range Brochure (PDF), the Echo Range Brochure (PDF) and the Tempo Range Datasheet (PDF).
How can I get more runtime?
Symphony models accept external battery modules: up to four on the 1.5kVA and 3kVA models, and up to five additional modules on the 6kVA and 10kVA models. The Echo ECH3000RMi2UER runs from one to four EBM72VRM2U battery modules, while the Echo 1kVA and 2kVA models use internal batteries only, as do the Tempo models. The selector shows the number of modules needed to reach your runtime.
What is a line-interactive UPS?
A line-interactive UPS, such as the Tempo range, passes mains power to your equipment through automatic voltage regulation and switches to its battery within a few milliseconds if the mains fails. It suits desktop PCs, network equipment and small offices. Use the UPS type filter in the selector to compare line-interactive and online models.
What is an online double-conversion UPS?
An online UPS powers the connected equipment from its inverter all the time, so the load is isolated from power cuts, voltage variation and electrical noise, and there is no break in supply when the mains fails.
What if my requirement is larger than the selector covers?
Contact Uniti Power technical support or find a Uniti Power partner. Symphony 6kVA and 10kVA units can also run in parallel, up to three units, using the SPYPK parallel card.
