Selection of UPS | UPS Power Renda | Shenzhen factory outlets

 How UPS power supply selection? First of all, we have to determine a good UPS power usage environment, specifically refers to the electrical environment, due to the back-up of UPS and line interactive UPS power supply is small, and there is a long power conversion time now generally only a single computer system used in the field and POS machines, and high power UPS power, tend to line UPS power supply; if harsh electrical environment (noise, radiation intensity, etc.), the selection of the power frequency Online UPS power supply, such as: workshops, construction sites, high-speed rail, etc; if the electrical environment is better, then use high-frequency online UPS power supply, such as server rooms, office. Second, the power to determine a good model, we have to determine the size of UPS models depending on the size of the charge. For example: a computer room has 8 PC, each PC power is 250W; a server, power is 700W; a network switch, power is 100W; now require two hours of power protection. Optional UPS power capacity is how it? Calculated as follows: Power Power = PC machine total load of + server + network computer 8 PC, 250W X 8 = 2000W 1 server 700W X 1 = 700W 1 network switch 100W X 1 = 100W total power over Total: 2800W. And because the common UPS power factor of 0.8, and the best working conditions UPS is the load rate of 70% -80%, the UPS power supply must have a 20% -30% capacity redundancy, the results obtained so UPS power supply is the total capacity of 2800W ÷ 0.8 ÷ 0.8 = 4375, so according to the common line UPS power supply models, we should choose 5KVA UPS power. Finally, the findings of the UPS power capacity, we also need to determine the size of the battery capacity according to equipment downtime. Battery discharge curve model specifications table generally determined based on the user battery backup time, you can from the battery vendors, to identify the discharge rate of the battery pack, as shown below: the battery discharge rate chart data, then the maximum current value of UPS, you can calculate the size of the battery, the specific algorithm: battery capacity = current ÷ long battery discharge rate. After obtaining the capacity of the battery capacity and UPS power supply, UPS power supply selection we would have been finished. Renda online UPS power supply can be divided into: frequency machine and two high-frequency machine, frequency and high-frequency machine can be divided according to the size of the voltage environment: single into a single type, three-three-type, three- single output type. Online UPS power supply has a very wide voltage range, for 1-1500KVA, and the output power stability, high accuracy, strong anti-environment capabilities, currently being accepted by more and more customers.
