What is the difference between a tower and rackmount 1kVA UPS?

A rackmount or rack UPS is designed for installation in a 19inch server rack or cabinet. Care should be taken to make sure that the internal depth of the server rack is sufficient for the depth of the UPS and its rear panel connections.

A rackmount UPS is supplied with sliding rails that are attached to the supporting structs in the server rack and then UPS is then attached to the rails. The UPS is also secured to the front of the UPS using M6 bolts and cage nuts. Rackmount UPS battery packs are also installed in a similar way if their weight can be supported by suitable sliding rails. If not, a heavy-duty shelf may be used. Rackmount UPS bypasses are also available for installation in a server rack or cabinet and plug-in ones will offer power distribution outlets.

A standalone or Tower UPS is designed for floor standing installation. Matching plug-in battery packs can be used for to provide extended runtimes. If a UPS maintenance bypass is required, a tower 1kVA UPS can use a wall mounted maintenance bypass. The bypass allows the UPS to be maintained or removed from a single-phase supply without interruption to the load.
