Choose protection
What does a UPS actually protect against?
A UPS provides temporary battery power when the incoming supply fails. An online double-conversion UPS also conditions the supply to sensitive equipment during normal operation. The protection you need depends on the equipment and the disturbances at your site. Identify which systems cannot stop, whether they need time to shut down or must keep running, and whether a generator will take over. Powermode can assess these requirements before recommending the UPS and battery arrangement.
Single-phase or three-phase UPS?
Single-phase or three-phase selection depends on your available supply and the loads the UPS must support. The input and output configuration must suit the electrical installation; building size alone is not a reliable guide. Share your distribution-board information, equipment schedule and expansion plans with Powermode. The assessment should also consider how critical circuits are distributed, available installation space and whether redundancy is required. Confirm the proposed configuration before ordering equipment or changing circuits.
How is a UPS sized?
UPS sizing starts with the equipment that must remain powered and its real demand. The UPS must support both the required kW and kVA, with appropriate allowance for starting demand and planned growth. Battery runtime is a separate design requirement. Send Powermode an equipment list, measured loads where available, the supply configuration and the required backup duration. A site assessment helps confirm the recommendation rather than relying on a building size or a single nameplate rating.
