Product Overview

The 8B0P0440HW00.000-1 (8B0P0440HW000001) is a high-capacity passive power supply module engineered for the B&R ACOPOSmulti drive system. This unit acts as the central energy entry point for the DC bus, converting a three-phase AC mains input into a stabilized DC voltage for multiple inverter modules. Designed for high-voltage (HV) applications and rated at 44 A, the 8B0P0440HW00.000-1 is optimized for wall-mounting within control cabinets, providing a robust power foundation for large-scale automation lines, CNC machining centers, and heavy-duty material handling systems. Its passive design offers a cost-effective and reliable solution for systems that do not require regenerative energy recovery to the mains.

Technical Configuration

This power supply is characterized by its high power density and specific integration requirements for the ACOPOSmulti backplane.

• High Power Capacity: Supports an installed load of up to 30.4 kVA, capable of powering several high-torque axes simultaneously across the shared DC bus.

• Passive Rectification: Utilizes a ruggedized bridge rectifier circuit to provide a stable DC link from a 380-500 VAC input, characterized by a low inrush current of 10 A.

• Thermal Management: Despite its high output, it maintains a low power dissipation of approximately 300 W at continuous power, supported by the efficient wall-mounting heat sink design.

• Safety Discharge: Features an integrated discharge capacitance of 0.9 uF, essential for managing the energy levels of the DC bus during power-down sequences.

Technical Specifications

FAQs

What is the minimum time required between power cycles?

The 8B0P0440HW00.000-1 requires a switch-on interval of greater than 120 seconds. This delay is critical to allow the internal inrush current limiting components to cool down and reset before the next power-up.

Does this passive module support energy regeneration?

No, this is a passive power supply module. Any regenerative energy produced by the motors during deceleration must be dissipated via an external braking resistor or stored in a capacitor module; it cannot be fed back into the mains.

What size cabinet is required for the 263 mm mounting?

The 263 mm refers to the specialized wall-mounting width for the ACOPOSmulti rack. Ensure the cabinet depth and height can accommodate the 6.1 kg unit while allowing for the necessary vertical clearance for cooling.

Engineering Installation and Power Safety Guidelines

• DC Bus Voltage Warning: WARNING: The DC bus carries lethal voltages (up to 800 VDC depending on mains input). After disconnecting the power, wait at least 5 minutes for the discharge capacitance to bring the bus voltage to a safe level before performing any service.

• Inrush Management: Ensure the upstream circuit breakers are sized to handle the 10 A inrush current. Rapidly cycling the power (faster than the 120 s interval) will bypass the soft-start protection and may cause the primary fuse to blow or damage the rectifier.

• Mechanical Integrity: The module weighs approximately 6.1 kg. Use the designated wall-mounting brackets and ensure the mounting surface is vibration-free. High-frequency vibration can lead to terminal fatigue on the high-current AC input connections.

• Wiring and Grounding: Use three-phase industrial cabling rated for at least 600 V and 50 A. The module must be grounded via the central grounding stud on the ACOPOSmulti rack to prevent common-mode noise from affecting the drive communication.
