Difference between Inverter & UPS? | Orrofast
What is UPS? An Uninterruptible Power Supply (UPS) is a device that allows an Electronic Devices to keep running for at least a short period of time when incoming power is interrupted. As long as utility power is flowing, it also replaces and maintains the energy storage. (Uninterruptible Power Supply) A device that provides battery backup when the electrical power fails or drops to an ...
