UPS power supply manufacturers detailed UPS capacity parameters and computing new UPS capacity requirements. Whether it is intellectuals engaged in weak electricity engineering or computer room projects, when designing a UPS power supply system in designing a computer room, the capacity calculation of the machine room equipment backup power supply, the reserve battery configuration, and usage time. Thus, the reliability, flexibility of saving investment and implementation, is a valid guarantee for communication equipment and computer load.
How do I calculate UPS capacity requirements? The following is how to teach you how to make quick and fast calculations?. UPS capacity parameters When you estimate the actual load, you should plan according to 80% of the actual rated capacity when actually running UPS. This can leave space for peak operating environments, and give you a corresponding capacity when installing a copy device, allowing you to get a little rising from the old equipment of the retired.
With regard to the planned load, 1.0pf value, the rated power is 100KVA / 100KW, if you keep the phase balance within 5%, it is enough to deal with. When the UPS has a PF value of 0.
9, a higher rated KVA value; 125kVA will supply you 112.5kW capacity, which will also supply some extra space. If you foresee the recent electricity will have a sharp rise, consider purchasing a modular UPS device.
There are two types of options: one is that the overall capacity will be higher than your needs, but only the required physical UPS and battery modules are installed. The other is the total capacity of the system, but the way to use firmware configuration is limited. Its output power is not higher than the value of the required.
Either way, only buy the right to buy, when you want to purchase an extra capacity. Saved is not just capital costs. When UPS is loaded to a higher capacity, its operational efficiency will be higher, so electricity operating costs are also saved.
Of course, there is 2N redundant UPS, in fact, you will run each UPS power supply with half of the total load, which makes it more important. Its operational efficiency can be less than 40% when it is low. Finally, considering generator load.
Different UPS design demonstrates different electrical properties to generators. Your electrical engineer or facility electrician should check the characteristics of both the UPS and generators to ensure that the power generator suddenly switches to the generator in an emergency. Calculating New UPS Capacity Demand Method 1) UPS Power Supply Calculation UPS Capacity (KVA) = Load Power (KW) ÷ UPS Power Factor ÷ 0.
7; (UPS power factor is typically between 0.8 ~ 1). 1UPS capacity (kVA): UPS capacity is generally represented by KVA, such as 10kVA, UPS capacity kVA * UPS power factor = kW, in general, KVA ≥ KW, only when the UPS power factor is 1, kVa = kW.
2 Load Power (kW): To carry the power of the IT device, generally use KW, such as 10KW. 3UPS maximum load power (kW) = UPS capacity (kVA) × UPS power factor (UPS power factor is typically between 0.8 ~ 1, check UPS parameters can be obtained, generally 0.
8). 4 When configuring UPS, it is recommended that the load power (kW) of the UPS is approximately 70% of the maximum load power (kW). 2) UPS battery capacity calculation UPS host actual power P real = rated power × 0.
8; then according to the selected host manual to detect the UPS battery DC voltage U, then current I = P real ÷ u. The specification parameters of the battery can be calculated according to the time h of delay. The parameters of the battery are typically used in peacetime (AH), that is, the number of batteries required is (P real ÷ u) XH.
3) UPS battery count because the UPS power supply is used to use the battery voltage of 12V, and the battery DC voltage is U, so the number of battery sections should be = (u ÷ 12V). UPS is aimed at my country's power grid environment and network monitoring and network system, medical system, etc. Third-generation frequency pure online intelligent UPS.
Learn to calculate the capacity requirements of UPS on procurement UPS has a great help. .
