Product Description:
The E0451-521-016A is a power supply board which is developed by Okuma. The power supply module is mainly required in Industrial automation applications for its diverse range of functions.
The E0451-521-016A Power Supply Board has a large round connector which is used for high density connections such as distributing multiple output voltages or signals to the CNC system. It is featured with visual indicators such as ISO 24V, +24V, +12V and +5V which confirm output voltage presence or status which is useful for diagnostics and operational checks. It performs its cooling via large heatsinks aided by internal fans which enhances thermal dissipation without requiring active external cooling. The inclusion of V-ADJ allows tuning the 5V rail slightly to match exact voltage requirements of connected logic circuits. It also includes a 2 pin round connector which serves as input for AC voltage or alarm signals. It is able to safely be installed inside electrical panels or industrial racks. It is specifically designed to meet the reliability and power needs of high precision machines. It has a zinc plated or chromated metal casing which prevents corrosion and enhances durability in industrial environments.
The E0451 power supply boards series module comes with alarm indicators which alerts for abnormal conditions such as over voltage, under voltage or thermal faults which helps it to perform timely maintenance. It has an electrically isolated 24V rail which helps prevent ground loops or signal interference. It also includes side mesh panels for airflow and thermal regulation which enables efficient airflow and maintains stable operating temperature internally. It is fit into standard cabinets or CNC racks which ensures mechanical compatibility.
Frequently Asked Questions about E0451-521-016A:
Q: Why does the E0451-521-016A use a V-ADJ for 5V tuning?
A: The V-ADJ allows precise voltage matching with sensitive logic circuits. It ensures stable performance in varying load conditions.
Q: How does the side mesh panel contribute to thermal management?
A: It enhances natural convection airflow, allowing internal heat to dissipate efficiently. This helps maintain consistent internal temperatures under continuous load.
Q: What is the benefit of using ISO 24V output in the E0451-521-016A?
A: The ISO 24V rail is electrically isolated to prevent signal noise and grounding issues. It ensures clean power delivery to sensitive components.
Q: Why is passive cooling preferred in the E0451-521-016A instead of active external cooling?
A: Passive cooling reduces mechanical complexity and potential failure points. It extends the module's operating life in industrial environments.
Q: What purpose do the alarm indicators serve in the E0451-521-016A Power Supply Board?
A: They provide immediate visual feedback on fault conditions. This enables quick diagnostics and reduces machine downtime.
