There aren't any businesses out there in the real world that can function well without electricity. Once the lights go out, the machinery stops whirring and the computer screens darken, you can expect an automatic halt in productivity. Not only does having your electricity go out mean that it stops your machines or employees from working, but if you are a business that deals with keeping people safe - like a doctor's office or hospital - you should worry about the possibility of electrical failure.
Three of the most common businesses to use a backup power supply include:
Office-Based Surgery Centers:
Medications Being Kept Cold
Life Safety Equipment
But really, a UPS backup power supply can be used anywhere in any place of business.
