The different waveforms

The different waveforms generated by UPSs

The UPSs generate various waveforms of the output voltage with specific characteristics and therefore different uses:

  • SINUSOIDAL wave
    It is the IDEAL waveform for feeding any type of load.
    It is normally generated by UPS Line-Interactive and On-Line.

Forma d'onda SINUSOIDALE

  • STEPS wave 
    It is a wave that very closely simulates a sinusoid.
    It can be used without any contraindication from computer systems; on the other hand, it can present problems with some types of linear load (motors, lamps, etc.).
    It has the advantage of economy.
    It is normally generated by UPS Line-Interactive and Stand-by.

Forma d'onda a GRADINI

  • SQUARE wave
    It is a wave too far from the ideal shape.
    Its use is always advised against.
    It is generated by some UPS Stand-by.
