What is the difference between a Line Interactive UPS and an Online UPS?

A Line Interactive UPS powers the load directly from mains under normal conditions, using AVR to regulate voltage fluctuations, and switches to battery when mains fails (transfer time: 4–6ms). An Online UPS continuously powers the load through its inverter with 0ms transfer time, providing the highest level of power protection.

How do I determine the right UPS capacity?

Calculate the total power consumption (watts) of all devices to be protected. Select a UPS model with at least 1.2–1.5 times the total wattage. For example, if total load is 400W, choose a UPS rated at least 600VA/480W or above.

Which series should I choose?

For basic home/office equipment with budget priority, choose the AK Series. For networking devices, NAS storage, and equipment with active PFC power supplies, choose the AP Series. For servers, medical equipment, telecom systems, and any mission-critical applications requiring the highest power quality, choose the AF Series
