Comparison of modular UPS and high frequency tower type UPS
1.The extension of modular Uninterruptible Power Supply is better
Tower type UPS need to buy a new expansion machine, the machine should be installed in place of the system in other UPS to bypass the new machine access system, the whole procedure is not only high investment, long time installation, existing power interruption risk load power down, when incorporated into the new machine because the entire system is in the bypass state. The modular UPS as long as the initial planning of the distribution system, you can increase the module to match the load of the upgrade, and in the expansion process to protect the original load of uninterrupted power supply.

2.Modular type UPS is easy to transport and install
Tower type UPS needs to install and transport as a whole, large single UPS will be more difficult. Such as the capacity of800kVA UPS weight is about 1500kg, the volume of more than 3 cubic metre, the tower type UPS will be lack of transport channel, transportation difficult to transport because of its high weight, modular UPS can be a separat to handling module and frame, on the other hand, most of the models can be transported separately, the problems can be easily solved.

3.The practical operating efficiency of modular UPS is high
At present, high frequency tower type UPS and modular UPS can achieve 96% of the highest efficiency value, but this is in the load rate of 50% or more. And as mentioned before, because the system is redundant and advanced planning, UPS load rate of common conditions in the 20~40% or so. High frequency tower type UPS can only achieve the efficiency of 94~95% under this condition, while the mainstream modular UPS generally have a “dormant module” characteristics based on a certain system redundancy, can sleep a certain number of modules (can be manually or automatically), work rate is relatively high in the area. So UPS system, which remain in the vicinity of efficiency the highest point of 96%.
