The operating time of a 3 kVA UPS (Uninterruptible Power Supply) depends on the battery capacity and the load supported. Typically, a 3 kVA UPS with a fully charged battery can provide backup power for approximately 10 to 20 minutes at full load. If the load is lower, for example 50% of its capacity, the runtime can be extended to approximately 30-40 minutes. The exact duration varies depending on battery size and inverter efficiency.
A 3 kW UPS generally refers to the power it can provide, and its run time is influenced by the battery capacity and charge.
For a 3 kW UPS, if fully charged, the battery can last between 10 and 20 minutes. However, if the load is less than full capacity, for example 50% or 1.5 kW, the inverter may last longer, possibly up to 30 minutes or more. The precise duration will depend on the specific inverter model and battery configuration.
The current consumed by a 3 kVA UPS can be calculated based on its rated power and input voltage. Assuming a typical input voltage of 230 V, current consumption can be calculated using the formula: Current (A) = Power (kVA) × 1000 / Voltage (V).
For a 3 kVA UPS, this equates to 3000 / 230, or approximately 13 amps. The exact current may vary slightly depending on the inverter design and input voltage.
The autonomy of a 6 kVA UPS depends on the capacity of its battery and the load used. Typically, a 6kVA UPS can provide backup power for about 10 to 20 minutes at full load. For lower loads, runtime may be extended. For example, if the inverter is operating at 50% capacity, this could last 30 to 60 minutes or more.
The exact duration is determined by the size of the battery and the efficiency of the inverter.
The runtime of a 1 kVA UPS varies depending on the load and battery capacity. Typically, a 1 kVA UPS can provide approximately 5 to 15 minutes of backup power at full load. If the load is less, the inverter can provide power for 20-30 minutes. The specific duration will depend on the model, battery size and efficiency of the UPS system.
