Product Description:

The E0451-521-037 manufactured by Okuma is a power supply board of the E0451 Power Supply Boards type. In industrial applications, the board is designed to be utilized for efficient management of power supply to maintain uninterrupted power flow and uniform machine operation.

Having 400/480 VAC as its input voltage range, E0451-521-037 delivers power that is stable in capacity and output of 13A and 10.8 kVA, respectively. It effectively delivers power output levels to facilitate heavy-duty machinery in high-performance drives through the provision of normal energy levels under heavy loads. The board accommodates a range of configurations, for example, 3.9 kW outputs of 390 VAC with 9.1 A at 3455 RPM, and 1.2 kW of 299 VAC — offering the flexibility to cater to the diverse requirements of distinct machine systems. It possesses 37.2 kVA of peak power capability along with the current rating of 47A and is suited to meet strenuous operating loads. Designed specifically for compatibility with three-phase power supplies, the E0451-521-037 ensures even power supply, maximizing the accuracy and reliability of related components. Consequently, it is suitable for applications with guaranteed and consistent power supply. The board has readily identifiable control and motor signal cable connectors — CN1 for controls and CN3 for motors — to facilitate effortless installation and interfacing. Linear layout requires shorter setup time and fewer opportunities for wiring mistake, so assembly of the system becomes streamlined. Titled as a "VAC Board II" in its PCB model, the E0451-521-037 is a testimony of Okuma's dedication to excellence in build quality and cutting-edge technology.

Okuma's E0451-521-037 delivers precise power control, adaptive output configurations, and integration ease. Featuring robust electrical properties and clean terminations, it guarantees effective transfer of energy for machine systems and is a robust component for deployment in industrial machinery that requires sustained and effective regulation of power.
