Vertiv standby (offline) UPS protect desktops, home offices, modems and routers, point-of-sale terminals and other small loads. In standby mode the equipment runs from utility power and the UPS switches to battery when the supply fails, which suits loads that need battery backup, surge protection and a clean shutdown rather than continuous power conditioning.
For voltage regulation during brownouts see Vertiv line-interactive UPS; for zero transfer time see Vertiv online UPS. Full catalog at Vertiv UPS.

Each product page lists the VA and watt ratings, outlets and runtime for that model.
Size by watts. Add up the watts of everything you plan to connect and pick a model whose watt rating clears that total with headroom. A desktop with a monitor and a router usually fits in the 500 to 900 VA models.
Standby or line-interactive. Standby units switch to battery on every sag or outage. If your power often dips, a line-interactive UPS with automatic voltage regulation corrects it without using the battery.
Voltage. The LVMT, LVT and MT120 models are 120 V; the IT-IEC models are 240 V with IEC outlets. Match the model to your outlet.
When a lead-acid model's battery wears out, you do not need a new UPS: see Liebert Vertiv replacement batteries and match the model on the unit label. We do not stock compatible lithium packs for the Power-UPS Lithium model.
What does standby mean?
The UPS passes utility power through and switches to its battery when the supply fails. It is the simplest topology and fits small, non-critical loads.
Which Vertiv standby model do I need?
Total the watts of your equipment, then choose a model whose watt rating exceeds it, in the voltage that matches your outlet.
Do these ship from Canada?
Yes. Orders ship from Canada.
