Description
B&R 8BVP0880HW00.004-1 is an active regenerative power supply unit
Product Title & Description
Model: 8BVP0880HW00.004-1 The B&R 8BVP0880HW00.004-1 is an active regenerative power supply unit for the ACOPOSmulti modular servo drive system. It converts 3-phase AC mains power into stabilized DC bus voltage for multiple axis inverter modules, supporting energy regeneration back to the power grid during motor deceleration. Designed for high-performance multi-axis motion control, this wall-mounted power unit is widely deployed in machine tools, packaging lines, printing machinery, metal forming and automated production systems, delivering high power density and excellent energy efficiency for complex synchronized motion applications.
Core Product Overview
The 8BVP0880HW00.004-1 belongs to B&R ACOPOSmulti drive family, serving as the central active power supply for multi-axis servo systems. Unlike passive power supplies, this active unit feeds braking energy from servos back to the mains grid instead of dissipating heat via braking resistors, greatly cutting energy consumption and reducing thermal load inside control cabinets. It has two slots for optional plug-in modules and supports DNA (Dynamic Node Allocation). Integrated temperature sensor interfaces continuously monitor internal thermal conditions. The unit builds a shared DC bus to supply multiple ACOPOSmulti inverter axes. Built-in protection functions include overvoltage, undervoltage, overcurrent, over-temperature and short-circuit detection. It works seamlessly with B&R Automation Studio for drive configuration, parameter tuning and diagnostic access, enabling precise control for up to hundreds of synchronized motion axes.

Installation & Configuration Guide
7.1 Pre-installation Preparation
Verify the part number and inspect the unit for physical damage, dents or broken terminals. Prepare wall mounting brackets, shielded power cables, DC bus cabling, matching line filter, ground conductors and Automation Studio software. Disconnect mains power before handling the unit. Wear ESD protection. Confirm mains voltage and check the total DC bus capacitance of all connected inverter modules.
7.2 Installation Steps
Mount the unit firmly on a solid cabinet wall following B&R mounting drawing. Maintain sufficient clearance around the unit for air cooling. Wire 3-phase AC mains input, protective earth and DC bus connections. Install matching line filter for EMC compliance. Connect temperature sensor wiring and communication cables. Tighten all power terminals to specified torque. Check wiring for short circuit, reversed polarity and proper earthing.
7.3 System Configuration & Commissioning
Open Automation Studio, add 8BVP0880HW00.004-1 and corresponding inverter modules into the hardware tree. Configure mains parameters, DC bus limits and protection thresholds. Download the project to the drive system. Perform power-up step by step with no-load test first. Verify DC bus voltage stability and regeneration function. Test all protection trips such as over-temperature and overcurrent. Record commissioning parameters and fault log baseline.
7.4 Maintenance & Precautions
Periodically inspect power terminal tightness, fan operation and dust accumulation on heat sinks during planned shutdowns. Check cable insulation and grounding integrity. Do not exceed rated input voltage or maximum DC bus capacitance. Do not open the power unit housing while energized. If faults occur, check mains supply, cooling system and wiring before replacing the power supply.
