The A1S61PN is a highly versatile and robust power supply module manufactured by Mitsubishi Electric for their MELSEC-A Series of programmable logic controllers (PLCs). This module is engineered to deliver stable, regulated DC power to the central processing unit (CPU) and other I/O modules housed within the same base unit. As a critical component of the MELSEC-A system, the Mitsubishi A1S61PN ensures the entire PLC rack receives clean and reliable power, which is fundamental for the deterministic execution of control logic and the accurate reading of field inputs. It is designed to convert a standard AC mains voltage into the low-voltage DC power required by the system’s digital electronics. The module is renowned for its efficiency, compact design, and built-in protective features, making it a cornerstone for system reliability. The inclusion of the A1S61PN in an automation setup guarantees that the control system is safeguarded against power fluctuations, thereby minimizing the risk of unexpected downtime and protecting sensitive electronic components from damage.

Main Features and Advantages
The Mitsubishi A1S61PN power supply module offers several key advantages that contribute to overall system integrity. Its wide input voltage range (100-240V AC) is a significant feature, allowing it to be deployed globally without requiring external transformers or hardware changes, which simplifies inventory and international machine design. The module provides a stable and high-capacity 3A output on the critical 5V DC bus, ensuring there is ample power for the CPU and a full complement of I/O and special function modules within the base unit. This eliminates concerns about power budget overruns during system design.
Built-in protection mechanisms are a core strength. The A1S61PN incorporates overcurrent protection that features auto-recovery, meaning the module will automatically reset once the fault condition is cleared, without needing a manual power cycle. This enhances system availability. Its robust design includes a high hold-up time, ensuring the PLC can continue to operate through brief power dips or interruptions, which is crucial for maintaining process continuity and executing a controlled shutdown sequence. The module’s compact form factor allows for efficient use of space within the PLC rack, and its high efficiency minimizes heat generation, contributing to the long-term reliability of all components in the enclosure.
Application Field
The A1S61PN is a foundational component in any industrial application utilizing the Mitsubishi MELSEC-A Series PLC platform. It is universally deployed in factory automation settings, providing reliable power for machine control systems across industries such as automotive manufacturing for controlling assembly robots and conveyor systems. In packaging and material handling, it powers the logic for palletizers, fillers, and sorting machines. The module is also found in plastic injection molding machines, metal stamping presses, and other industrial machinery where the MELSEC-A Series is a preferred controller due to its robustness and performance.
Beyond discrete manufacturing, the A1S61PN serves in process control applications like water treatment plants for controlling filter sequences and chemical dosing, and in building automation for managing HVAC and lighting control panels. Its reliability makes it suitable for applications where unscheduled downtime is costly. Essentially, wherever a MELSEC-A Series PLC is specified to handle complex control tasks in a demanding environment, the A1S61PN power supply is there to provide the stable and clean power required for flawless operation.
