Calculation method for APC UPS host capacity and battery capacity. How about the capacity of APC UPS host and battery? This is a question that many people ask. Today, we will tell you the calculation method for the capacity of lithium battery UPS host and battery capacity.
Principles for Capacity Selection of APC UPS Hosts
When the load is a computer load, lithium battery UPS host capacity calculation method:
Need to design lithium battery UPS host capacity=design load power: 0.8 (APC UPS output power factor).
For example, the power statistics of the computer room load are as follows:
Digital hard disk monitoring and recording host: 350W, 10 units, totaling 3500W.
Display: 120W, 8 units, totaling 960W; How to calculate the capacity of lithium battery UPS host and battery capacity.
Camera: Average 2W, 120 cameras, totaling 240W.
Monitor: 150W, 5 units, totaling 750W.
Matrix host: 180W.
The total power of the above devices is 5630W.
Need to design UPS host capacity=5630W: 0.7 (UPS output power factor)=8042.9W
The UPS power is an integer, and most consider future expansion. Choosing a 10KV AUPS host is ideal, so APC SURT10000UXI-CH is chosen.
APC UPS host battery capacity selection principles
When the load is a non inductive load such as a computer, the calculation method for UPS battery capacity is:
Need to design UPS battery capacity=design load power ÷ nominal voltage x time ÷ UPS output power factor.
Assuming that the above-mentioned computer room needs to continue power supply for 2 hours after a power outage, then:
5630W: 192V (nominal voltage, determined according to actual parameters) x2H: 0.7 (UPS output power factor) ≈ 84AH.
Therefore, unless there are special requirements, we should choose a UPS host with a power of 10KVA and a battery pack capacity of 100AH. Based on this, we should select the host model APC SURT10000UXI-CH and pair it with 16 12V100AH batteries.
