Comparison of characteristics between modular UPS and tower UPS
Time of issue:2023-05-15
Views:
Modular UPS has many advantages compared to traditional tower UPS, but in different regions and industries, there are some controversies due to different cognitions. This article will not make too many comparisons. Only the relevant features are compared as follows. The investment comparison is for reference only. The prices of products of different manufacturers are different, and the actual situation shall prevail.
