Questions & Answers

Yes. The 9SX, like its 9130 tower UPS predecessor, is designed to protect enterprise class IT hardware and industrial applications with PLCs and other automation devices. The 9SX continues Eaton's long history of online, double conversion UPS technology for mission critical battery backup protection.

There are multiple 9SX platforms, which each have their own configuration of internal batteries. The 9SX 700VA and 1000VA use (3) internal batteries, the 1500VA utilizes (4) internal batteries, and the 2000VA and 3000VA models use (8) batteries. All models except the 9SX 700VA have a compatible external battery module with twice the number of batteries as the UPS. Keep in mind that adding batteries increases the stored energy for more runtime and does not increase the load carrying capacity of the UPS.

No. Most customers prefer to put the external battery modules next to the UPS, but it is not necessary. Eaton does provide six foot 9SX battery extension cable accessories in order for the EBM to be placed up to five feet away from the UPS.

The 9SX is designed to accept generator power in most applications without any special action. Some generator applications may have high THD due to an undersized generator or other electrical infrastructure challenges. For these applications, the RPO port can be reprogrammed through the front menu as an on-generator signal thereby opening up the input voltage parameters for increased compatibility. The 9SX manual can provide more detail on using the RPO port for on-generator signal. Read more on planning for UPS and generator compatibility.

The static bypass is a fast-acting semiconductor switch that enables a UPS to transfer back to utility power in milliseconds in the event of an overload or internal fault. The result is extremely high availability even when things may go wrong, such as an overload or an inverter failure. All Eaton 9 series product utilize online, double conversion topology and contain an internal static bypass.
