1.1 How do I choose tower or rack mount UPS?
- The difference of tower and rack mount UPS are their appearance and installation ways. We suggest you consider the following factors:
1. Do you have security concerns?
2. Is the demand of power and/or backup time possibly expanded?
3. Is the installation location dedicated for the load (such as a server room)?
4. Do you concern the floor space for the UPS?
When you have more “Yes” to the questions above, likely rack mount UPS’s suit for your application more.
Generally speaking, rack mount UPS is easy to manage and has high security but needs the rack which might cause additional cost. Imagine the scenario of a couple UPS’s and several devices which use the output power from the UPS’s. You can see many power cords there. If the devices are used for communication, probably you will see many communication cables, such as Ethernet and telephone cables. If all these devices are not in one rack, you can imagine how terrible it would be when you need to check or set up one of these devices. When using a rack, all cables are well arranged, the operation panels are all aligned. When the demand power increases and the rack still has space, the rack-mount UPS can be installed immediately. If the rack is not enough, it is time to have an overall plan. Furthermore, depending on the rack height, many rack-mount UPS can be installed in one rack and occupy only one footprint.
Once the devices, including servers, communication devices and UPS’s are installed in one rack, usually the rack is locked with a door, then these devices are secured and not touched accidentally.
On the other hand, tower UPS still has its suitable application scenario. For example, if this UPS is in open space and the devices using its backup do not locate together, the tower is suitable. The most popular application of tower UPS is entry level where you can place it just close to your PC and modem, just plug and play.
