About the machine with the advantages of high frequency UPS
1. In order to increase the service life of klk-fc (12v24ah), it is recommended to select models with more than 30% rated output power. For example, if the system needs a 100W power supply, it is recommended to select a model with an output power rating greater than 130W, and so on, which can effectively improve the service life of klk-fc (12v24ah).
2. In addition, the operating ambient temperature of klk-fc (12v24ah) and whether there is additional auxiliary heat dissipation equipment need to be considered. When the ring temperature is too high, the rated output of klk-fc (12v24ah) needs to be reduced. Please refer to the product specification for the derating curve of ambient temperature to output power.
Technology is always developing. Now electronic technology has entered the digital era. It is a historical development law for new technology to replace old technology. The competition level of all walks of life has increased significantly. It is not the case in the field of UPS power supply.
Advantages of power frequency ups and high frequency UPS
1. Low power consumption (related content: UPS quotation)
Under the same index, for example, when the input power factor is required to be more than 0.95, the power frequency machine UPS must be added with harmonic filter or changed to 12 pulse rectification, that is, adding a device in front and an output transformer will add two links more than the high frequency machine UPS, as shown in Figure 1. Due to the influence of both, the efficiency of power frequency machine UPS is 5% lower than that of high frequency machine ups. At the same capacity of 100kW, the power frequency machine UPS consumes 50000 kwh more than the high frequency machine UPS every year! This is of far-reaching significance in today's call for energy conservation and emission reduction.
2. High input power factor
Generally, the input circuit of power frequency UPS below 200KVA adopts thyristor 6 pulse rectification, the input power factor does not exceed 0.8, and the harmonic current is 30%. If the front boundary generator, the capacity of the generator shall be at least 3 times the power of UPS; In case of single-phase low-power UPS, the capacity of the generator shall be at least 5 times the power of ups.
Power frequency UPS is not easy to adapt to the change of ± 15% of input voltage; The high-frequency UPS even adapts to the change of input voltage of more than ± 30%, which greatly prolongs the service life of the battery.
In short, the high-frequency machine UPS can not only completely replace the power frequency machine UPS in performance, but also have more characteristics than the former.
