Description
Product Name: 8520-OPS1 Allen Bradley Central control module
Product details:
The Allen-Bradley 8520-PS1 Main Power Supply Assembly is the primary power supply module designed for use with the Allen-Bradley 9/260 and 9/290 CNC Controller systems.
-
Function: It serves as the main power source, supplying essential power to the system motherboard, the main CPU board, and the operator panel power supply (which powers the display and interface).
-
Connection: It connects to the processor module via the P12 port and receives input power through a terminal block.
-
Protection: It includes an input fuse to protect the power module and the connected components (like the CRT).
-
Monitoring: It features a line monitor that detects a loss of AC input power, ensuring system stability.

3. Product Advantages (产品优势)
-
Reliable Power: Designed specifically for the robust 8520 CNC platform, ensuring stable and clean power delivery to sensitive control components.
-
Wide Input Range: The ability to operate from $90 \text{V}$ to $265 \text{V AC}$ provides flexibility and tolerance for varying line voltages common in industrial environments.
-
System Integration: Fully integrated with the 8520 system architecture, providing dedicated power to the main CPU and operator interface.
-
Power Loss Detection: The built-in line monitor helps the CNC system manage brief power interruptions or dips, aiding in smooth operation or controlled shutdown.
4. Important Considerations (注意事项)
-
Part Number Verification: Always verify the exact part number (8520-OPS1 vs. 8520-PS1) required for your specific controller to ensure compatibility.
-
Installation: Installation should only be performed by qualified personnel following the official Allen-Bradley documentation. Ensure the system power is completely disconnected before installation or maintenance.
-
Fuse Rating: Use only the specified $8 \text{A} / 250 \text{V AC}$ fuse for replacement. Using an incorrect fuse can damage the unit and the CNC system.
-
Environment: Ensure the operating environment stays within the specified temperature and humidity ranges to prevent premature failure.
5. Product Application (产品应用)
The Allen-Bradley 8520-PS1 Main Power Supply is primarily used in Computer Numerical Control (CNC) Machining Applications.
-
CNC Controllers: It is a critical component for the legacy Allen-Bradley 9/260 and 9/290 CNC Controller systems.
-
Manufacturing: Used in various automated manufacturing processes where the 8520 CNC platform controls machine tools like lathes, mills, and machining centers.
