What is a Power Frequency Online UPS?
A Power Frequency Online UPS is designed to provide a constant and reliable power supply by converting incoming AC power to DC and then back to AC. This type of UPS continuously powers the connected devices through its inverter, which ensures there is no interruption during a power outage.
What is a Line Interactive UPS?
A Line Interactive UPS also offers battery backup during power outages, but it operates differently. It maintains the connection between incoming power and the load while regulating voltage fluctuations through an autotransformer. This system is typically used for smaller setups that don’t demand high power quality.
