Listen to the market vendors themselves, such as C3KS, the actual only about 2K more than a day, is how?
Communication function means: UPS has data interface above, can connect computer, communicate with computer. After installing special software, it can realize advanced management of UPS power supply. For example, when the UPS battery is low, the host is notified to be placed in standby or resting state.If you don't need it, you can use the backup UPS power supply without the communication port.
Performance parameter. UPS uninterruptible power supply as a protective power supply equipment, its performance parameters are of great significance, should be our choice when considering the key. The wide input voltage range indicates that the utilization capacity of the power supply is strong, and the output voltage and frequency range are small, which indicates that the regulation capacity of the power supply is strong and the output is stable. The waveform distortion rate is used to measure the stability of the output voltage waveform, while the voltage stability indicates the stability of the output voltage when the Santak UPS power is suddenly switched from zero load to full load.
Power efficiency, power factor, and conversion time. UPS uninterruptible power supply efficiency, power factor and conversion time are important parameters to characterize the performance of UPS, which determine the protection capability of the load and the utilization rate of the city power. The better the performance, the stronger the protection ability. In general, the off-line UPS has the worst protection to the load, the online interaction is slightly better, and the online type can solve almost all the common power problems. The cost, of course, increases as performance increases. Therefore, users in the purchase of Santak UPS power supply, should be based on the load on the power requirements and the importance of different loads, and select different types of UPS.
The energy of the input power does not translate into 100% of the effective energy used by the components in the host, so a conversion efficiency is present.Power conversion efficiency = the instant power output of the power supply for the host / the instantaneous power of the input power * 100%1. different power products, the conversion efficiency is different;2., the same power supply products, in different working conditions, the conversion efficiency is also changing.
Notice whether the UPS is online or backup. What about battery quality?. Is there communication function?.Conversion efficiency is the ratio between the UPS input current rating and the final output value. The closer to 1, the better.
