Specifications & Features
| Feature | Detail |
|---|---|
| Model / Variant | EVI 1100VA Line Interactive UPS (sometimes labelled UPS1100EUK2IE2 etc.) |
| Capacity | 1100 VA / ≈ 600 W |
| Topology | Line-Interactive – includes AVR (Automatic Voltage Regulation) to handle voltage dips (brownouts) & surges without switching entirely to battery immediately. |
| Input Voltage Range | Roughly 140 V – 300 V AC (nominal 230V) for mains operating range. |
| Output Outlets | • 4 universal outlets in many versions – these can accept various plugs. EVI+2realmer.co.ke+2 • Some versions list 2 universal + 2 IEC outlets. |
| Battery | Lead-acid sealed battery(s), typical configuration is 2 × 7 Ah in some versions. |
| Recharge Time | ~ 6 ‒ 8 hours to full charge after depletion. |
| Runtime / Backup Time | Around 10-15 minutes depending on load (heavier load = shorter time) for many versions. |
| LCD / Display & Monitoring | Equipped with LCD Panel for monitoring; also includes monitoring/control software so you can see battery status, input/output voltage, load etc. |
| Automatic Voltage Regulation (AVR) | Built-in “Boost & Buck” AVR to correct under-voltage and over-voltage without using the battery prematurely. |
| Cold Start Function | Yes — the UPS can be started from battery even when mains is out. |
| Protection & Software Features | Intelligent battery management; overload protection; audible alarms for low battery / overload; in many cases USB port or other interface for alerts or shutdown scripting. |
| Operating Conditions | Temperature ~ 0-40 °C in many listings. |
Pros & Useful Situations
Some of the strong points of this unit, and where it works well:
-
Good power buffer for home/office setups — can handle a desktop PC + monitor + network gear for short outages.
-
AVR helps prevent damage from voltage instability and reduces stress on battery by reducing number of times full battery power is used.
-
Cold-start useful in areas with frequent blackouts.
-
LCD + monitoring software is handy for seeing when to replace batteries / gauging loads.
-
Multiple universal outlets = flexibility in connecting devices.
Limitations & Considerations
Things to watch out, or possible downsides:
-
Even though it says 600 W, actual usable battery backup drops fast as you approach that maximum. For heavy loads, runtime may be just a few minutes.
-
The battery is lead-acid; over time its capacity degrades, so real-life performance falls.
-
Simulated sine wave (if that’s what it is; many line-interactive units are) may not be ideal for very sensitive electronics or for PSUs that require pure sine wave. Sellers don’t always list waveform explicitly.
-
Size, weight, noise (fan / switching) under high load might be higher.
-
Warranty on battery is often shorter than unit, so check battery warranty.
