What are the points to when selecting uninterrupted power suply?

When selecting an uninterrupted power supply (UPS), consider the power capacity to ensure it meets your equipment's needs, typically measured in VA or watts. Evaluate the type of UPS—offline, line-interactive, or online—based on your power quality requirements and the sensitivity of connected devices. Additionally, assess the runtime you need during outages and look for features like surge protection, battery management, and monitoring capabilities for optimal performance and maintenance. Finally, ensure the UPS has a good warranty and reliable customer support.
