Voltage spikes, brief power dips, or a sudden blackout can damage your equipment or wipe out your data in seconds. A UPS (Uninterruptible Power Supply) is the device built to solve exactly that problem. So how do you pick a model that will actually protect what you own? Let’s break down the key criteria in plain terms.
Step 1: UPS Type (Topology)
- Standby: the most affordable option — it switches to battery only when the power actually drops. Good for PCs, routers, and POS terminals.
- Line-Interactive: also regulates voltage (AVR) without switching to battery for minor fluctuations. The best all-round choice for home and office use.
- On-Line (double-conversion): continuously passes power through itself, delivering a perfectly clean sine wave at all times. Required for servers, medical equipment, and industrial systems.
Step 2: Capacity (VA/W)
- Add up your load: total the wattage of everything you’ll connect and leave a 20-30% margin.
- Typical figures: a single PC with a monitor usually needs 600-1000VA; a server rack or several workstations will need models from 2 to 10 kVA and up.
Step 3: Runtime and Batteries
- Internal battery: a compact solution for a short runtime (5-15 minutes) — enough to shut down safely.
- Expandable/modular UPS: lets you add extra battery packs to extend runtime, scaling from a small office to a full server room.
