A quality UPS power supply should have the following: UPS hosts have a strong ability to adapt to the grid environment, UPS for various load adaptability, flexibility in system configuration and redundancy features.
UPS ability to adapt to various load
Refers to here is not such as voltage stability, waveform distortion, frequency stability, dynamic response time, reserve conversion time of conventional indicators, and to pay attention to the special load configuration, UPS is working correctly. Such as the strong capacitive load, impact load, rectified and filtered input load, with the same input power linear transformer load. Performance indicators have to be examined with a non-linear load capacity (output power factor), with periodic shock loads capacity (peak system off) \ with randomness ability to impact load (instantaneous overload or short circuit endurance and ability to protect), three-phase unbalanced load capacity.
The UPS Host To have a strong ability to adapt to the grid environment
Installing a UPS, we must first consider the ability to adapt its complex grid environment, including the ability to adapt diesel drag. To examine the performance indicators have allowable variation range input voltage, input power factor and UPS two-way anti-interference ability. Input voltage allows a range of hours, to make UPS frequent into the battery-powered state; low input power factor means that the input nonlinear current components, which will not only damage the environment, but also lead to supply equipment and transmission the expansion of the capacity of the configuration, a waste of energy; including anti-jamming performance can inhibit the interference of all kinds of interference and reverse grid formed on the grid.
Improve battery performance, and to enhance the battery management
About the battery, pay attention to two issues, is necessary to the selection of the excellent performance of the battery, and to consider the use and management capacity of the UPS battery. Work of advanced UPS vendors (such as APC, Exide, Silcon, Deltec, etc.) in this regard is very effective. Such as configuration based on the physical and chemical characteristics of the battery charging circuit monitors the battery state of charge at any time, set the charge and discharge maintenance through the software itself, the battery float voltage temperature compensation, hot under normal operating conditions replace the battery.
System configuration flexibility and redundancy features
When a UPS capacity does not meet demand, can be used multiple parallel, in order to improve reliability, you can use multiple redundant configuration, this modular technology in the UPS system configuration, multiple parallel technology, series and parallel redundant technology, bypass repair technology, these improve the flexibility of the power supply system, scalability, maintainability and improve reliability are obvious role.
Intelligent and network protection capabilities
The intelligent UPS and network protection is a new technology, users have come to realize and expanding the scope of use of the process, the selection should pay attention to the following three questions. First, the functionality of the software, should normally be safely shut down the system, state test records system, UPS's own management system, and even include environmental monitoring system. Second, the type of operating system software support (compatibility) and operability. Third, the best software testing and certification of the operating system vendors. Such as the United States APC, because their software vendor certification such as Novell, Microsoft and many other operating systems, the company's software is very easy to get running the operating system vendor support and compatible operation of the guarantee.
