Beckhoff C9900-P224 Industrial Power Supply Unit

The Beckhoff C9900-P224 is a robust power supply unit specifically designed to provide reliable power for Beckhoff Industrial PCs. This compact, DIN rail-mountable unit accepts a wide range of AC input voltages (100‑240 V AC) and converts it to a stable 24 V DC output, making it an essential component for building stable and efficient industrial control systems. A key feature of the C9900-P224 is its capacity to work in conjunction with a C9900-U330 battery pack to create an uninterruptible power supply (UPS). This ensures that the connected PC can safely shut down or continue operating during a mains power failure, protecting against data loss and system crashes. The unit is distinguished by its high efficiency, compact dimensions, and a dedicated UPS output for connecting a control panel.

Technical Specifications

The C9900-P224 power supply unit operates with an input voltage of 100‑240 V AC, accommodating fluctuations commonly found in industrial settings. It is capable of delivering a total power output of up to 150 W, depending on cooling conditions. The primary DC output is 24 V DC with a maximum output current of 10 A, suitable for powering Industrial PCs and other automation components. Additionally, the unit generates other necessary voltages: +5 V, +12 V, and +5 VSB (standby). In conjunction with a C9900-U330 battery pack, it provides an integrated UPS solution. During a power failure, the unit can maintain a display screen for the PC via a dedicated UPS output, which has a maximum load capacity of 1.4 A. The unit’s dimensions are 50 mm (W) × 25 mm (H) × 104 mm (D), and it weighs approximately 120 g. It operates within an ambient temperature range of 0°C to 55°C. The power supply unit must only be used in conjunction with Beckhoff Industrial PCs.

• UPS-ready design with C9900-U330 battery pack (sold separately)

• Dedicated UPS output (1.4 A) for maintaining screen display during power loss

• Multiple output voltages: +24 V, +12 V, +5 V, and +5 VSB

• Compact DIN rail mountable design for space-saving cabinet installation

• High reliability with robust protection against electrical disturbances

• PC_ON and power status functions for controlled system shutdown

UPS Functionality

The C9900-P224 is a UPS-ready power supply. When combined with the C9900-U330 battery pack, it forms a complete uninterruptible power supply system for Beckhoff Industrial PCs. Upon a power failure, the unit instantly switches to battery power, maintaining the PC‘s operation. The integrated software components allow for a controlled shutdown of the operating system, preventing data corruption. The dedicated UPS output (max. 1.4 A) ensures that the screen display for the PC can be maintained even during a power outage. This feature is particularly valuable in critical automation tasks where loss of control or data could have severe consequences. The unit also provides PC_ON and power status signals, enabling external monitoring of power conditions and system health.

Applications

The C9900-P224 is used as a dedicated power source for Beckhoff Industrial PCs in a wide range of industrial automation applications. Typical use cases include machine control systems in packaging, printing, textile, and woodworking machinery; data acquisition and processing in test stands and measurement systems; operator interface and visualization platforms for manufacturing lines; and edge computing devices in Industry 4.0 architectures. The UPS capability makes it particularly suitable for critical systems where mains power is unreliable or where an orderly shutdown is required to preserve data integrity.

Installation and Wiring

Install the C9900-P224 on a standard 35 mm DIN rail by snapping it into place. Connect the AC input (100‑240 V) to the designated terminals (L, N) according to the installation instructions. Connect the DC output (+24 V and GND) to the Industrial PC’s power input. If a UPS configuration is desired, connect the C9900-U330 battery pack to the dedicated terminals. For external monitoring, connect the PC_ON and power status signals to a PLC or monitoring system. The unit includes a UPS output for connecting a control panel to maintain display during power loss; ensure the load does not exceed 1.4 A. All wiring should be performed with the system power switched off.

Environmental and Compliance

The C9900-P224 is CE and UL certified, and meets FCC Class A digital device limits for industrial environments. It is designed for pollution degree 2 environments and must be installed in a control cabinet with appropriate protection. Operating temperature: 0°C to 55°C. Storage: -20°C to 65°C. Atmospheric humidity: maximum 95%, non-condensing. Sinusoidal vibration (EN 60068-2-6): 10 to 58 Hz: 0.035 mm, 58 to 500 Hz: 0.5 G (~5 m/s²). Impact resistance (EN 60068-2-27): 5 G (~50 m/s²), duration 30 ms. Do not use the power supply unit in areas where there is a risk of explosion.

Conclusion

The Beckhoff C9900-P224 is a high-quality, reliable power supply unit engineered for the rigorous demands of industrial automation. Its UPS-ready design, compact form factor, and robust electrical specifications make it an essential component for any control system that requires a stable and uninterrupted power source for its core computing hardware.
