The Beckhoff CX1100-0920 UPS module is a compact and reliable power protection solution designed to safeguard embedded PC systems against short-term power interruptions. Operating as part of the CX series, this UPS ensures stable and continuous supply to connected controllers, allowing critical processes to complete properly and preventing data loss during power disturbances. Its capacitor-based storage technology provides robust and maintenance-free performance, making it a durable choice for automation environments.

The CX1100-0920 operates with a 24 V DC power supply, supporting an input tolerance of -15% to +20%. It provides a maximum output current of 1.1 A at 24 V DC, sufficient to maintain stable power delivery for Beckhoff CX-series embedded PCs and their essential components. With a storage capacity of 40 As, the UPS module delivers enough energy to bridge short-term outages, ensuring that data can be securely written and critical system tasks are safely concluded before shutdown.

A key advantage of the CX1100-0920 is its capacitive storage design. Unlike battery-based UPS systems, capacitor storage eliminates the need for regular replacement, significantly reducing maintenance requirements. This technology also allows for rapid charging and long service life, making it particularly well suited for industrial environments where reliability and minimal downtime are critical.

The UPS module integrates seamlessly with Beckhoff embedded PCs through its 16-bit ISA interface (PC/104 standard). This connection enables the UPS to communicate directly with the CPU, coordinating system responses during a power interruption. By working in tandem with the CPU, the CX1100-0920 ensures that the automation system can carry out controlled shutdown procedures, reducing the risk of corrupted data or incomplete processing cycles.

Diagnostics and system monitoring are straightforward thanks to the module’s LED indicators, which provide clear status updates for the 24 V DC input, 24 V DC output, and charging state. These LEDs allow operators and engineers to quickly assess UPS performance, simplifying commissioning and ongoing system monitoring.

With a maximum power loss of just 2 W, the CX1100-0920 is highly efficient, keeping energy consumption low while maintaining dependable backup power functionality. Its compact form factor allows it to fit neatly alongside CX controllers within control cabinets, making it a space-efficient solution without compromising reliability.

In practice, the CX1100-0920 is ideal for applications where data integrity and system stability must be guaranteed during short power interruptions. It provides engineers and operators with confidence that their Beckhoff embedded PCs will continue to function long enough to safeguard critical information and ensure smooth system recovery.

In summary, the Beckhoff CX1100-0920 UPS module combines capacitor-based energy storage, dependable communication with embedded CPUs, and easy-to-read diagnostics into a compact, efficient design. It is a proven solution for protecting industrial automation systems, offering reliable short-term backup power during service phase deployments.
