Blacktec RT 11 6K 240V 20×9Ah battery module

The Blacktec RT 11 6K 240V 20x9Ah Battery Module is a powerful extension of your backup power system, designed to work with the Blacktec RT 11 PRO 6K / 6 kVA series UPSs. It provides significantly extended runtime for servers, network devices, CCTV systems, and critical IT infrastructure. The Blacktec RT 11 6K 240V 20x9Ah Battery Module is a robust, scalable solution for users who require extended runtime and the high reliability of a 6 kVA backup power system.

Main features:

• Extended backup time for 6 kVA UPS

A set of 20 9 Ah (12 V) batteries ensures stable UPS operation even during prolonged power outages. At 50% load, the system can operate for up to approximately 22 minutes, and at full load for up to approximately 9 minutes, providing time for safe system shutdown or continued operation in emergency mode.

• Professional 19" Rack design

The 19" rack-mountable housing allows for easy integration of the module into existing server infrastructure. The module can be mounted in racks or used as a free-standing unit (tower), providing flexible configuration in server rooms and technical rooms.

• Reliability for critical systems

High-quality batteries used in the module ensure long life and stable operating parameters. The module is ideal for applications requiring high availability: servers, monitoring systems, telecommunications devices, and industrial automation.

• Plug Play and easy expansion

The module is equipped with quick-connect Plug Play connectors, so installation doesn't require opening the UPS or additional wiring – simply connect the module with a single click. The ability to connect multiple battery modules in series allows for flexible scaling of the total backup time depending on the user's needs.

• Compact and versatile 3U chassis

The compact 3U housing makes it easy to place the module in a 19" rack without taking up excessive space. The rack/tower design means the module can be used both in professional server cabinets and in smaller office or technical installations.
