E4809-045-074-A

The Okuma E4809-045-074-A, part of the E4809 CNC Boards series from Okuma, is a professional-grade power board engineered for industrial automation applications. The module operates from a 200-240 VAC input voltage range at 50/60 Hz and delivers a stable 5 VDC output at up to 20 A for a total power output of 100 W. Designed for rack mount installation in server cabinets and control panels, this compact board measures 120 mm x 220 mm x 80 mm and weighs just 2.5 kg, optimizing cabinet space and simplifying system integration. Power delivery is handled through a robust screw terminal connector type for secure termination under vibration-prone conditions. Thermal management is ensured by an integrated forced air cooling system that maintains optimal operating temperatures. The board is factory-certified to CE, UL Certified safety standards, aligning with global electrical protection requirements.

High-performance operation is supported by an operating temperature range of 0°C to 40°C and storage resilience from -20°C to 60°C, enabling consistent functionality under varying environmental conditions. The forced air cooling method works in conjunction with the board’s layout to reduce thermal hotspots during continuous 24/7 operation and prevent overheating of critical components. The efficient conversion architecture offers low ripple and noise, producing a clean DC output ideal for sensitive embedded computers, control systems, and communication devices. Input power conditioning and regulation are finely tuned to accommodate line variations within the specified voltage and frequency ranges, ensuring stable system voltage and minimization of transient disturbances. Rack-mount design and screw terminal connectivity reduce installation time and maintenance effort, supporting rapid integration into existing automation systems. The compact dimensions facilitate high-density installations without sacrificing airflow or service accessibility.

Engineered for continuous industrial operation, the E4809-045-074-A delivers reliable power in server cabinets, CNC machines, automated production lines, and instrumentation racks. Compliance with CE, UL Certified safety standards ensures adherence to global regulations for electrical protection and operator safety. The robust platform supports integration with PLCs, CNC controllers, and embedded systems where stable low-voltage DC output is critical. Its compact 120 mm x 220 mm x 80 mm form factor and 2.5 kg weight minimize space requirements and simplify cabinet layouts. Overall, this board offers a combination of electrical stability, thermal management, and rugged construction required in demanding industrial automation environments.
