ABB APOW-11C 3AUA0000061236 Power Supplement Board

The ABB APOW-11C (Part No. 3AUA0000061236) is a Power Supplement Board designed for use in ABB’s advanced drive and automation systems. Its primary function is to deliver stabilized auxiliary power to various internal control and logic subsystems within the drive architecture, acting as a backbone power distributor for other control modules such as CPU boards, interface modules, and I/O components.

APOW-11C is engineered to ensure continuous and clean power delivery to critical subsystems, particularly in high-demand industrial environments where voltage fluctuations, EMI, or transient spikes can compromise operational integrity. This module is often used in conjunction with ABB’s ACS800 and ACS880 drive families or similar platforms, supporting the internal electronics that manage drive operations.

Its compact yet rugged PCB design, high-efficiency power regulation, and proven field reliability make it an integral part of drive system continuity and diagnostic readiness.

Frequently Asked Questions (FAQ)

1. What is the main role of the APOW-11C board?

   It supplements or replaces internal power delivery in ABB drive systems by providing stable regulated voltages for various subsystems.

2. Is this board compatible with the ACS880 series?

   Yes, it is commonly used in ACS800 and ACS880 systems to ensure consistent power distribution.

3. Can it be replaced independently of the main drive?

   Yes. It is a modular component and can be serviced or replaced independently without removing the full drive.

4. What type of mounting does the board support?

   It supports chassis or backplane mounting with pre-drilled holes for industrial enclosures.

5. Does it include protection features?

   Yes, including over-voltage, short-circuit, and thermal overload protections.

6. What kind of outputs does it provide?

   Regulated DC outputs such as +5V, +12V, or +15V depending on the internal system requirements.

7. Is the board RoHS compliant?

   Yes, it adheres to RoHS directives for environmentally safe electronic design.

8. How can I verify if the board is operating correctly?

   System diagnostics from the main control unit usually report module status, or visual LEDs may be present depending on model revision.

9. Can it power external field devices?

   It is not designed to power field I/O directly but to supply power internally within the control system.

10. What happens if the board fails?

    Dependent modules (CPU, I/O, or interface modules) may lose power, causing the system to halt or signal a diagnostic error.
