E4809-820-006-A
by Okuma
The Okuma E4809-820-006-A is a robust power control PCB in the E4809 CNC Boards series, designed by Okuma for industrial automation applications. This high-performance board delivers a bending performance of up to 1.2 mm on sheet steel and supports a maximum bending angle of 160 degrees, enabling precise control in metal forming processes. Its primary function is to regulate and distribute power to CNC bending and cutting mechanisms, ensuring accurate and reliable operation of roller shears across the entire working width.
Incorporating cutting-edge components, the E4809-820-006-A features a cutting mechanism with roller shears capable of handling up to 0.8 mm steel thickness, and a bending beam thickness rated at 15 mm for solid structural integrity. The board enhances non-ferrous bending power by 30%, thanks to two large electrolytic capacitors dedicated to power filtering and voltage smoothing. A FUJI blue relay manages high-current switching, while a small transformer supports efficient power conversion. Additional surface-mounted diodes provide circuit protection and rectification, and inductors minimize electrical noise to improve stability. Surface-mounted resistors are strategically placed to control current flow, ensuring precise regulation throughout the power delivery network.
Measuring approximately 800 mm x 200 mm and weighing approximately 420 kg, this compact power board is built for durability and seamless integration. Mounting holes at each corner secure the board within enclosures, while multiple external connectors allow compatibility with a variety of CNC modules and wiring configurations. With three top beam lifting positions and an upper cheek stroke of 80 mm, the PCB supports flexible installation parameters. Its high efficiency power regulation, stable operation under load, and comprehensive circuit protection features make the E4809-820-006-A an ideal choice for industrial environments where reliability, efficiency, and precise automation control are paramount.
