Introduction
A 900W Uninterruptible Power Supply (UPS) is an essential device for providing backup power during electrical outages. It is crucial to understand how long such a UPS will last on battery power alone, as this enables users to plan appropriately for power interruptions.
Understanding UPS Capacity
The capacity of a UPS is usually measured in Volt-Amperes (VA) and Watts (W). For instance, a 900W UPS may have a VA rating of 1500VA. The VA rating accounts for reactive power, while the wattage refers to the real power capacity.
Calculating UPS Runtime
The runtime of a UPS is primarily dependent on the load connected to it and the battery's total capacity. A general formula to estimate UPS runtime is:
Runtime (in hours) = (Battery Capacity in Ah x Battery Voltage) / Load in Watts
Where:
- Battery Capacity in Ah is the amp-hour rating of the battery.
- Battery Voltage is typically around 12V or 24V for common UPS units.
- Load in Watts is the total power consumption of the connected devices.
Runtime Example for a 900W UPS
Consider a UPS with a battery capacity of 12V, 9Ah and a load of 900W. The runtime can be calculated as follows:
Runtime = (9Ah x 12V) / 900W = 0.12 hours, or approximately 7.2 minutes.
This example assumes the UPS is operating at full load capacity. Reducing the load will extend the runtime proportionately.
