Blacktec RT 11 3K 72V 6×9Ah battery module

The Blacktec RT 11 3K 72V 6×9Ah battery module is designed to work with Blacktec RT 11 PRO 3K / 3 kVA UPSs, significantly extending backup time during a power outage. Ideal for server rooms, IT systems, monitoring, and installations requiring reliable emergency power.

The most important advantages

• Extended backup time - a set of 6 9 Ah batteries ensures stable UPS operation even during long-term power outages.


• 19" Rack Design (2U) - The compact housing fits into standard server cabinets and can also work as a desktop module on a shelf or desk.


• Reliable operation - high-quality batteries guarantee long life and safe operation in critical systems.

Performance and assembly

The module significantly extends the autonomy of a 3 kVA UPS – at 50% load, it can provide up to 27 minutes of operation, and at 100% load, approximately 10 minutes of backup time. This is enough time to safely shut down systems or activate an additional power source.
Thanks to the Plug Play system, the module is connected using ready-made quick connectors, without soldering or having to open the UPS casing. It is also possible to connect multiple battery modules in series to flexibly increase the system's total autonomy.
