Frequent power cuts in Iraq are more than an annoyance, they are a real threat to your computer, your files and your network gear. A good UPS buys you the precious minutes you need to save your work and shut down safely, and it shields sensitive components from voltage swings. In this guide we explain how to pick the right VA rating and how to estimate the runtime you will actually get.
How to choose the right UPS- VA rating: add up the wattage of your devices, multiply it by roughly 1.6 to get the VA you need, and leave a 20% safety margin.
- Topology: Line Interactive is plenty for a desktop PC and a modem, while Online (Double Conversion) is the better fit for servers and equipment that cannot tolerate voltage swings.
- Battery capacity: bigger batteries (12V-9Ah instead of 12V-7Ah) mean longer runtime when the power goes out.
- Waveform: look for Pure Sine Wave to protect modern power supplies and sensitive equipment.
- Outlets and LCD screen: an LCD screen shows the battery level and the load, and the number of outlets decides how many devices you can plug in.
- Replaceable battery: a battery you can swap yourself extends the life of the unit and saves you from buying a whole new one later.
For the home, modem and router (light load)
If your goal is keeping the internet and the camera running through a cut, an 850VA or 1000VA Line Interactive unit is enough and delivers good runtime on small loads.
For desktop PCs and gaming (medium load)
A desktop with a monitor needs more headroom. A 1500VA or 2000VA unit gives you a comfortable safety margin and enough time to save your work and shut down safely.
For servers and sensitive equipment (Online)
For systems that cannot tolerate any fluctuation at all, Online technology with a pure sine wave output is the best choice for full, uninterrupted protection.
How long does the runtime last? It depends on the load: the fewer devices you plug in, the longer it runs. Never run a laser printer or a heater off a UPS, because they draw an enormous amount of power.
When should I replace the battery? Usually every 2-3 years, or whenever the runtime gets noticeably shorter.
Every UPS is available at the best prices with cash on delivery and shipping to all 18 provinces of Iraq. Order now and protect your gear with confidence.
