E4809-770-105-B
by Okuma
The Okuma E4809-770-105-B module is a Power Supply Module manufactured by Okuma in the E4809 CNC Boards series for industrial automation applications. This board accepts a wide range of Input Voltage from 100-240V AC to suit global mains standards. It delivers a regulated Output Voltage of 24V DC at a nominal Output Current of 5A, meeting the requirements of standard control logic rails. With a Power Rating of 120W and operation over Frequency bands of 50/60Hz, the module ensures compatibility with both legacy and modern power grids. The compact form factor with Dimensions of 200mm x 150mm x 60mm allows integration into standard control enclosures. Weighing just 1.5kg, the design facilitates quick installation and handling by service personnel.
To ensure robust performance, the unit incorporates comprehensive Protection Features including Overvoltage, Overcurrent, and Short circuit safeguards. The board’s Type as a dedicated power supply module provides stable DC bus voltage for multiple servo drives and control circuits. Its Operating Temperature range from 0°C to 50°C covers typical factory-floor conditions without derating in confined cabinets. The Mounting style is Panel Mount, enabling secure attachment to rack fronts and minimizing cabling strain. The build quality balances thermal management and structural rigidity to maintain continuous operation under industrial loading. Thermal clearance around the module supports adequate airflow to prevent overheating within high-density equipment racks.
Designed for seamless integration into Okuma CNC control architectures, the E4809-770-105-B aligns with the E4809 series modular philosophy. It simplifies maintenance through its plug-in panel mount arrangement and standardized form factor. The uniform footprint allows adjacent modules and accessory boards to be installed with minimal spacing, optimizing rack density. By stabilizing drive electronics with 24V DC and integrated protections, it enhances system reliability and reduces downtime. This power supply module is ideally suited for industrial automation, CNC machining centers, and precision manufacturing environments.
