Product Introduction

The BUS3-15/30-31-010 is a highly efficient, regulated system power supply module from Baumüller’s innovative b maXX 5000/6000 series. This unit is engineered to act as the central DC power hub for sophisticated automation systems, converting a standard 3-phase AC line voltage into a stable and precisely regulated 24V DC supply. Its core function is to provide clean, reliable power not only to the control electronics but also to the DC bus of associated servo drives within the same system stack. The BUS3-15/30-31-010 is more than a simple power converter; it is an intelligent system component designed for seamless integration into a modular drive architecture.

Technically, the BUS3-15/30-31-010 is positioned as a high-performance power management solution. It features a significant power boost capability, allowing it to deliver double its rated current for short durations to handle peak demands, such as during motor acceleration. Its role within an automation cabinet is critical: it ensures all connected components—from the system controller and I/O modules to the servo drives—receive a consistent voltage level, immune to fluctuations in the mains supply. The value of the BUS3-15/30-31-010 lies in its ability to enhance system stability, improve energy efficiency, and simplify the overall electrical design.

Core Advantages and Technical Highlights

The BUS3-15/30-31-010 distinguishes itself through its exceptional efficiency, intelligent power management, and robust design tailored for industrial duty cycles.

High Efficiency and Active Power Factor Correction: A primary advantage of the BUS3-15/30-31-010 is its operational efficiency of over 94%. This high efficiency minimizes power loss in the form of heat, reducing the thermal load on the control cabinet and lowering the total cost of ownership. Furthermore, the integrated Active PFC circuit ensures a near-unity power factor, reducing the reactive power drawn from the grid. This not only complies with strict energy standards like EN 61000-3-2 but also leads to lower energy costs and avoids penalties from utility providers.

Intelligent Power Management and Communication: The BUS3-15/30-31-010 is equipped with a CANopen interface, transforming it from a passive component into an intelligent node on the network. This allows for real-time monitoring of critical parameters such as output voltage, current, temperature, and operating status. The power boost feature, delivering 30A for 5 seconds, is intelligently managed to support the peak power demands of connected servo drives without requiring oversizing of the PSU. This smart capability of the BUS3-15/30-31-010 enables a more compact and cost-effective system design.

Modularity and System Integration: Designed to the standard b maXX frame size, the BUS3-15/30-31-010 can be mounted directly alongside Baumüller’s servo drives and system controllers, creating a compact, unified, and wiring-efficient cabinet layout. The built-in buffer choke simplifies the connection to a shared DC bus, allowing for energy exchange between axes (e.g., regenerative energy from a braking motor can be used by an accelerating motor). This modularity and the resulting clean system topology are key benefits of using the BUS3-15/30-31-010.

Typical Application Scenarios

The BUS3-15/30-31-010 is ideally suited for multi-axis motion control systems where a centralized, robust, and intelligent DC power source is required.

In complex automated machinery, such as packaging lines or printing presses, the BUS3-15/30-31-010 serves as the central power supply for the entire motion control system. It powers the system controller, the DC bus for multiple servo drives controlling individual stations, and the associated safety and I/O modules. The stability of the BUS3-15/30-31-010 is critical for ensuring that all axes operate synchronously without voltage dips that could cause faults or production defects.

For applications in material handling, such as multi-axis gantry robots or automated storage and retrieval systems (AS/RS), the power boost capability of the BUS3-15/30-31-010 is essential. It reliably provides the high peak currents needed when several axes accelerate simultaneously. The CANopen interface allows system integrators to monitor the health of the power supply proactively, scheduling maintenance before a potential failure causes unplanned downtime. The robustness of the BUS3-15/30-31-010 ensures reliable operation in demanding 24/7 industrial environments.
