UPS power supply system designed using parallel redundant UPS power supply system technology, dual-bus technology, eliminating single points of failure in the system bottlenecks,this designed is currently the primary way to improve power supply reliability of the traditional UPS system.Modular UPS power supply reliability have a full range of technological breakthroughs.

1. traditional UPS parallel redundant hidden danger

Traditional UPS power must exist AC loop when parallel redundancy running, when circulation is too large will result in system downtime, which cannot be overcome by traditional UPS circuit;
 when Traditional UPS power parallel redundancy running, such as any power internal static switch is damaged, resulting in power outages;
 when Traditional UPS power parallel redundancy running, such as streaming misallocation and the load power of inconsistencies, resulting in power outages;
 when Traditional UPS power parallel redundancy running, such as its online expansion ,upgrading and maintenance high risk, improper operation will result in a total power outage;
Conclusion: the traditional number of power UPS and more reliability decreases.

2. advanced modular UPS design ideas

Circuit structure fundamentally solved the circulation on the UPS power module and the effects of redundancy, in theory, can be unlimited and redundancy;
Centralized bypass static switch mode, and switch the control circuits and devices and separated in the structure main power, to avoid the risk of downtime;
Master-slave control technology using rank, each power module input, output, charging using the advanced and reliable technology of power-sharing, the system runs without bottlenecks;
Use of multilevel distributed control concepts, power module, monitoring module, the static switch modules are online hot-pluggable, expansion, upgrading, maintenance, zero risk;
Conclusion: the module UPS reduced the risk factor of the system itself, and UPS the full protection of the load.
