Product Overview

The 8B0C0320HC00.002-1 (8B0C0320HC00.002-1) is a high-performance auxiliary supply module from the B&R ACOPOSmulti drive system. Engineered for high-voltage (HV) industrial environments, this unit is designed to provide stable 24 VDC auxiliary power to drive electronics and peripheral components. With a dual-output configuration (1x 32 A and 1x 5 A), it ensures reliable power distribution for complex multi-axis motion architectures. The module features flexible mounting options—including cold plate or feed-through installation—allowing for optimal heat dissipation in dense control cabinet designs, which is critical for maintaining long-term system stability in demanding industrial processes.

Technical Configuration

The 8B0C0320HC00.002-1 is built upon the robust ACOPOSmulti backplane architecture, ensuring seamless interoperability with other drives and power supplies in the line.

• High-Voltage Handling: Supports a nominal voltage of 750 VDC, with a continuous operating range between 260 to 800 VDC.
• Auxiliary Output: Provides dual 24 VDC outputs (32 A and 5 A), sufficient for powering high-load auxiliary systems, including cooling fans, sensors, and secondary control electronics.
• Thermal Efficiency: Designed for cold plate or feed-through mounting, this module excels in environments where internal air cooling is limited, enabling the transfer of heat directly to external heat sinks.
• Compact Integration: Despite its high power density, the module maintains a compact footprint suitable for integration into modular ACOPOSmulti backplane systems.

Technical Specifications

FAQs

Why is the cold plate or feed-through mounting recommended for this module?

The auxiliary supply generates significant heat under full load. By utilizing cold plate or feed-through mounting, you can remove this thermal energy from the control cabinet, allowing for a higher packing density of components without exceeding safe operating temperatures.

What is the function of the internal DC bus capacitance?

The 220 nF internal capacitance acts as a high-frequency buffer, helping to stabilize the DC bus voltage and mitigate transient spikes that can occur during high-speed drive switching operations.

Can this module be used in a standalone configuration?

No, the 8B0C0320HC00.002-1 is specifically designed to operate as part of the ACOPOSmulti backplane system, drawing its primary DC input from the shared bus.

Installation and Operational Guidelines

• Thermal Interface: If using cold plate mounting, apply a high-quality thermal interface material (TIM) between the module and the cooling plate to eliminate air gaps. Ensure the surface contact is uniform to maximize heat conduction.
• Input Voltage Safety: Ensure the incoming DC bus voltage is within the specified 260 to 800 VDC range. Operating outside this window may trigger undervoltage or overvoltage protection circuits, disabling the module to prevent hardware damage.
• Humidity Control: While the module is built for industrial operation, be mindful of the storage and transport humidity limits (up to 95%). If the module has been stored in a cold environment, allow it to acclimate to room temperature before installation to prevent condensation on the internal PCBs.
