Why use an uninterruptible power supply ?

 Failure of the supply voltage causes unwanted machine and plant status which means risks:  Hazard to health and life  Machine damage, tool fractures, rejects and data losses  Minimization of downtime  Critical loads (e.g., for security functions) must remain powered with 24 V even when the power network fails.
