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.
