Overview
A home office desk, a small network corner or the floor beside a workstation is the setting for this tower UPS, which stands upright on its own. It backs up outlets with a lead-acid AGM battery, regulates voltage and shows status on an LCD.
Outlet count, voltage regulation and an LCD lead the case for it in a layout that needs no rack. The runtime is listed as a short window, without a load figure.
Who it's for
Desktops, routers and small electronics that need a clean shutdown window during a power cut. People who want long runtime or a rack unit should look at other UPS models.
Pros and cons
- Automatic voltage regulation
- LCD status screen
- Tower layout needs no rack
- USB drive bundled
- Short listed runtime
- Load for runtime not stated
- Heavy battery unit
Performance notes
The lead-acid battery stores energy that the inverter converts to household power during an outage, so connected load decides how long it lasts. Output capacity in watts caps what can be plugged in, and voltage regulation smooths sags and surges on the line. The listed runtime is a short window for a clean shutdown.
