Product Description:
The constructive Circuit Board is built for several industrial systems by Okuma . The Okuma is a well-known control technology company that creates intelligent solutions by combining software and hardware to enhance industrial automation procedures.
The E04809-045-019D circuit board is a high-class motor control unit used in spindle types. The board carries a total weight that is approximately 0.75 kg by making it a compact and powerful component for applications of CNC. It functions to control spindle speed along with torque parameters which guarantees exact machining accuracy. The multi-layer PCB contains numerous integrated circuits (ICs) alongside resistors and capacitors and additional electronic parts that assist in processing and controlling functions. The E4809 series board uses different power semiconductors including IGBTs or MOSFETs in motor drive operations which require large heat sinks and cooling fans to dissipate heat effectively. It accepts input power from a 200V/220V three-phase network and operates within a 50-60Hz frequency band. Power regulation involves Bridge rectifiers, substantial electrolytic capacitors as well as heavy-duty relays or contactors to establish an efficient and stable DC output.
The E04809-045-019D circuit board on right side, holds the unique SDU-600W transformer unit that functions to step voltage when required. Safety features in the system include fuses in combination with circuit breakers together with metal oxides for proper protection against electrical surges and overcurrent events. The board temperature stays in check throughout the operation duration because of the two enough and well-suited axial cooling fans that provide continuous ventilation and moisture-free setup. This CNC board features durable construction which allows processing in industrial settings where efficiency with durability remains the primary priority.
