How to determine uninterruptible power supply? How to match the UPS uninterruptible power supply? UPS uninterruptible power supply battery pack capacity reasonable configuration, it is very important to run normal and efficient operation throughout the power supply system. Due to the different systems and equipment, the selected UPS power model and configuration are also different. Depending on the delay capability, determine the capacity size of the required battery, indicated by the AH value, calculate the time hours of discharging when the current amperage is given.

How to determine if the power supply is determined? About the user, how to configure long delay UPS battery capacity is a problem that must be understood, according to the uninterruptible power supply of the total load capacity, generally selected: UPS capacity> = Load capacity ¡Â 0.8, ie load capacity should be 80% of UPS rated capacity. Choosing 80% Load is important to consider the impact current of the load start and the user's future expansion.

The UPS uninterruptible power supply capacity determines that the appropriate UPS is selected according to the load capacity and nature, which ensures both the power quality of the UPS, reduces the fault rate, and saves investment, and improve economic benefits. In general, the determination of the UPS capacity is important to meet the current load, while also considering several factors: (1) Impact of load properties on UPS output power. The output power of most UPS manufacturers in the product manual refers to a value at which the load power factor is one 0.

8 (lag), and the load capacity of the UPS power supply is closely related to the load power factor, when When the load is pure resistance or inductance, the inverter will have a decrease in the power of the rated machine at power. Therefore, when considering the UPS capacity, power conversion should be performed on different load power factors. (2) Uninterruptible power supply UPS capacity is not too large, so that it is overwork.

Although over light-load operation is conducive to reducing the damage probability of the inverter, it may cause the mainstream power failure, the battery discharge current is too small and the battery pack is depressed, and the battery pack is depressed, and it is permanent Sexual damage. (3) The UPS capacity should not be too small to make it long in the heavy duty operation. Thus, although some investments can be saved, but since the inverter is overloaded, its output waveform will distortion, and the output voltage amplitude is too large.

(4) About the situation of the communication room is large, the load is constantly changing, and when the UPS capacity is configured, the medium-term development trend should be considered, and the model can be selected in the selection. In order to increase the medium-long load capacity, expand its output capacity through the UPS parallelor. How does UPS uninterruptible power supply? The capacity size of the battery also determines the length of the UPS uninterruptible power supply to the power supply time.

The UPS battery pack capacity configuration is not only unable to meet the UPS backup time, but also due to too large battery discharge ratio, which seriously affects the performance of the battery, and bring great hidden dangers to the system's stability operation; the opposite is not in the budget In sufficient circumstances, it is necessary to choose a large-capacity UPS power battery component to be a waste of resources and cause pressure in economic aspects. When determining the capacity configuration of the UPS uninterruptible power supply battery pack, we can calculate the determination of the battery according to the constant power discharge data table supplied in the battery brand sample data. Model and capacity.

How to choose a suitable UPS uninterruptible power supply capacity? If you choose not properly, the following is usually the following cases, one is too small, that is, the so-called small maele truck, it is likely to cause damage to the equipment; the other is too large, resulting in waste of funds. Therefore, the capacity of UPS correctly selects an important thing for network managers.
