Choose a UPS for the load, not just the number on the box

This page outlines UPS types, comparison criteria, and the information to prepare before an enquiry. For UPS design integrated with the electrical system and critical equipment, see the UPS solution page.

Three UPS technologies to distinguish clearly

Example of a compact floor-standing UPS with no brand shown
STANDBY

General equipment that can tolerate a brief power-transfer time

Check the load characteristics and the transfer time the equipment can tolerate

Example of a rack-mounted UPS with no brand shown
LINE-INTERACTIVE

Equipment that needs voltage regulation together with backup power

Check the voltage range, AVR system, and output waveform

Example of an online UPS cabinet and battery cabinet with no brand shown
ONLINE

Critical loads that need continuous power conversion

Check efficiency, Bypass, heat management, and the maintenance plan

Information needed to size the UPS

UPS sizing should account for power, starting current, backup time, and electrical conditions—not just total wattage.

  1. 01
    Load list

    Equipment name, quantity, power draw, and criticality.

  2. 02
    Backup time

    How long the equipment must keep running or needs for a safe shutdown.

  3. 03
    Input power

    Phase, voltage, installation point, and existing protection devices.

  4. 04
    Expansion plan

    Potential future loads and space for batteries or Bypass.

Information for comparing models once the product list is ready

This table does not yet list models, prices, or brands that Danocore has not confirmed.

ItemWhat to checkWhy it matters
Capacity VA / WRated capacity and actual power drawEnsure the UPS supports the load type and allows for expansion
Output waveformCompatibility with the equipmentReduce the risk of choosing UPS technology that does not match the load
BatteryBackup time, service life, replacement, and spacePlan costs and ongoing maintenance
Bypass / MonitoringMaintenance method and alertsMaintain continuity while the system is tested or repaired

The product list is awaiting confirmation

Danocore still needs to confirm brands, models, specifications, stock, pricing, warranty terms, and distributor status, so products and purchase buttons are not yet shown.

Send a load list for an enquiry

Do you already have a list of equipment that needs backup power?

Send equipment nameplates or a load list with the required backup time so we can narrow down the UPS types to consider.
