How to choose the right UPS?
Последнее Обновление 5 лет назад
Main criteria- UPS Topology (VFD, VI, VFI), modulated or sinus wave output in battery mode
- Required power capacity in Watt
- Autonomy time
- Size and model type (i.e. rack mountable? Limited space?)
- Outlets (IEC, Schuko, French, Terminal)
To determine appropriate UPS power requirement consider the below.
- Sum the maximum power consumption of all loads
- Consider in-rush currents
- Consider characteristic of the load (inductive vs capacitve)
- Calculate efficiency drop of your loads if modulated wave output
- Consider safety margin
- Extension cards for additional communication SNMP, Modbus, AS400
- Selecting appropriate battery pack for expected autonomy time
- Human Interface Device USB protocol
