The Beckhoff CX2100-0904 Power Supply Unit with Integrated UPS is a reliable and compact solution designed specifically for the CX2033 Embedded PC. Combining stable power delivery with capacitive uninterruptible power supply (UPS) functionality, this module ensures continuous operation and protection of critical system data during unexpected power loss.
The unit is powered by a 24 V DC input with a tolerance range of -15% to +20%, providing robustness in environments where voltage fluctuations are common. With a maximum output of 45 W, the CX2100-0904 supplies ample power to the CPU module and connected peripherals, supporting stable operation across a wide range of automation applications.
One of its key strengths is the integrated capacitive UPS, which offers a backup capacity of 75 As. Unlike traditional battery-based systems, the capacitive design is maintenance-free, ensuring long-term durability and consistent performance. This UPS function enables the system to save process data, shut down gracefully, or bridge short-term power failures, significantly reducing the risk of data loss or system corruption.
The CX2100-0904 also supports automatic recognition of Beckhoff E-bus and K-bus terminals, making it highly versatile for a range of system configurations. This feature allows the power supply to adapt seamlessly to Beckhoff’s modular I/O architecture, ensuring compatibility with both new and legacy setups. With a bus current supply of up to 2 A, the unit delivers reliable power to connected I/O modules without the need for additional components.
Diagnostic LEDs on the module provide clear feedback on operating conditions, including input voltage, UPS status, and bus supply. This real-time visibility simplifies system monitoring and allows maintenance teams to identify and resolve issues quickly, improving system availability and reducing downtime.
Compact in design, the CX2100-0904 integrates easily into control cabinets, conserving space while delivering essential UPS functionality directly at the embedded PC level. Its industrial-grade design ensures consistent performance in demanding environments, making it a dependable choice for applications in manufacturing, logistics, building automation, and process control.
By combining power delivery and UPS functionality in a single device, the CX2100-0904 reduces system complexity and eliminates the need for external UPS hardware. This integration not only saves space but also streamlines installation and lowers overall system cost.
In summary, the Beckhoff CX2100-0904 Power Supply Unit with Internal UPS is a compact, efficient, and reliable solution for ensuring stable operation of the CX2033 Embedded PC. With its integrated 75 As capacitive UPS, automatic I/O bus recognition, and robust 45 W power output, it provides a future-proof foundation for safeguarding automation systems against power interruptions.
