How do you determine what type of UPS power supply you need? Generally, personal office and home users can consider backup models. For example, the Shantui UPS power supply is inexpensive and compact, making it an ideal partner for personal computers. It has a high cost performance; for online users, servers or precision instruments of small and medium-sized systems, it uses online or online interactive UPS power supply, which can better resist various infringements from the power grid, and its functions are perfect, and most of them With intelligent monitoring and network connectivity, remote control and intelligent management. For large critical equipment and systems, high-power Yamate online UPS power supplies are essential for stable power protection. Specifically, how to determine the required power (VA) size? Then list all the devices that need to be protected. Don't forget the monitor, terminal, and external hard drive. The voltage and current data of each device can be found on the backplane, and the VA value can be obtained by multiplying the two. Some devices use watts to indicate electrical energy requirements. See the wattage multiplied by 1.4 to get the approximate VA value. The power of the overall equipment is based on its rated number. Aggregate the VA values ​​of all devices and add 30% of the expanded capacity to the system for future system upgrades.
How to configure the backup delay time? The selected UPS power supply model and configuration are different due to different systems and equipment. The standard UPS power supply itself has its own UPS battery , which can continue to supply power for several minutes to several tens of minutes after power failure. The long-acting UPS power supply is equipped with an external battery pack, which can meet the needs of users to continue power supply during long power outages. The backup time can be designed from a few minutes to a dozen hours or more. The general long-life UPS power supply backup time is mainly limited by factors such as UPS battery cost, installation space and battery recharge time. Generally, in a place where the power environment is poor and the power outage is relatively frequent, the UPS power source and the generator are used to supply power. When the power is cut off, the UPS power supply is powered by the battery for a period of time. If the power failure time is long, the standby generator can be started to continue to supply power to the UPS power supply, and then switch to the mains supply when the utility power is restored. Battery power supply time is mainly affected by factors such as load size, battery capacity, ambient temperature, and battery discharge cutoff voltage. According to the delay capability, determine the capacity of the required battery, which is expressed by the AH value of the ampere-hour, and is calculated by the number of hours of discharge when the current amperage is given. The general UPS configuration is calculated by the following formula: UPS power (VA) × delay time (hours) ÷ UPS power supply DC = required battery safety hours (AH) Take the C3KS delay 4 hours as an example, let's calculate ::(Note: The starting DC of Santa C3KS is: 96V) 3000 volts × 4 hours ÷ 96V = 125AH The result is that the battery needs 125AH to meet the 4 hours of power supply, but the ordinary UPS battery generally does not have a set of capacity of 125AH 8 Only (because the starting DC of the C3KS is 96V- (the standard DC voltage of the UPS at the factory), the general battery is mostly 12V DC, 96V (UPS starting DC voltage) ÷12V (battery DC voltage) = 8. So 8 batteries As a group) UPS battery.
We can choose a set of 100AH ​​batteries to configure it; the delay time is: 100AH ​​(UPS battery capacity) × 96V (UPS start DC) ÷ 3000V (UPS power) = 3.2 hours can also choose 2 groups (16 The 65AH UPS battery is configured in parallel! The delay time is: 65AH×2×96V÷3000VA=4.16 hours. The standard startup DC voltage of the US UPS power supply voltage at the factory: MT1000SC1KS C2KS-C3KS C6KS-3C20KS 3C3-10KS- -3C340KS 24VA 36V 96V 240V 384V US UPS power supply voltage output power factor is 0.7; such as the C11KS maximum support load power: 1000V × 0.7 = 700W, so the maximum support load of the mountain C1K is 700W, and so on!! Note: Generally, in order to better use the UPS power supply, it is recommended that the UPS power supply should not be used without load/full load or overload. The best load power of the UPS power supply is about 70%-80% of its standard load, such as C1K. The load is 500-600 (w) load! This can better take advantage of the advantages of the UPS power supply and extend the life of the UPS power supply!
