How do I know what size UPS I need?
Add up the wattage of everything it must hold, then decide how many minutes you need — usually enough for a clean shutdown or to ride through a short cut. We work the model out from those two figures.

Overview
APC Smart-UPS Supplier in the UK
A UPS is only right if it holds your actual load for as long as you need. We size APC Smart-UPS units from the equipment list and the runtime you want, rather than guessing from a VA figure on a box.

Which Smart-UPS range fits
Back-UPS protects a desk. Smart-UPS protects servers, switches and comms cabinets with sine-wave output and proper management. Smart-UPS On-Line (SRT) is for sites where the mains is unreliable or the load is sensitive.
| Deployment | Range | Typical load | Output | Best for |
|---|---|---|---|---|
| Back-UPS | Desktop, till, router | Stepped | Single devices | |
| Smart-UPS (SMT / SMC) | Comms cabinet, small server room | Sine wave | Most business sites | |
| Smart-UPS On-Line (SRT) | Server rooms, sensitive kit | Double conversion | Poor mains, critical loads |

FAQs
Questions We Are Asked Most
How long do APC batteries last?
Typically three to five years depending on temperature and cycling. We supply genuine replacement batteries for units already installed.
Do I need a network management card?
If the UPS protects servers, yes — it is what lets them shut down gracefully and lets you get an alert before the battery runs out.
