The Beckhoff CX1100-0930 is a UPS (Uninterruptible Power Supply) module designed to provide short-term backup power for Beckhoff CX series Embedded PCs. It is intended to safeguard automation systems against sudden power interruptions by using capacitor-based storage technology, ensuring that systems can continue operating long enough to perform a controlled shutdown or secure important process data.

Operating from a 24 V DC supply with a tolerance of -15% to +20%, the CX1100-0930 is built for compatibility with standard industrial power systems. It can supply a maximum output current of 2.0 A at 24 V DC, making it suitable for supporting both the controller and its immediate peripherals during short-term outages. With a storage capacity of 40 As, it provides sufficient bridging time to ensure orderly system shutdown, data consistency, and protection of critical control processes.

Unlike traditional battery-based UPS systems, the CX1100-0930 employs capacitor storage technology. This design offers a number of advantages for industrial environments:

Maintenance-free operation, since capacitors do not require replacement as batteries do.

Fast recharge times, enabling the system to quickly restore readiness after a discharge.

High durability, with a longer service life and resilience against frequent short power drops.

The module also features integrated diagnostics LEDs, which provide operators and maintenance teams with clear visual indicators of system status. These LEDs display the state of the 24 V DC input, the 24 V DC output, and the charging process, enabling quick and effective monitoring of power conditions. This visibility supports proactive maintenance and minimises downtime by alerting users to power-related issues before they escalate.

For seamless integration into Beckhoff systems, the CX1100-0930 connects to the CPU through a 16-bit ISA (PC/104 standard) interface. This ensures fast and reliable communication with the Embedded PC, allowing the UPS to coordinate its functions with the controller’s shutdown and restart routines. The compact housing, with dimensions of 95 mm x 100 mm x 91 mm, makes it easy to install within a standard control cabinet without consuming excessive space.

Built with Beckhoff’s emphasis on industrial-grade reliability, the CX1100-0930 is engineered for continuous use in demanding environments. Its fanless, solid-state design ensures consistent long-term performance, free from the maintenance challenges associated with moving parts or battery-based UPS systems.

In summary, the Beckhoff CX1100-0930 UPS module is a compact, efficient, and reliable backup power solution for CX controllers. With capacitor-based energy storage, robust diagnostics, and seamless integration, it ensures automation systems remain protected during power disturbances. It is an ideal choice for industries where data integrity, operational stability, and reliable system shutdown are essential.
