Product Description:

The 8B0M0120HW00.000-1 is a modular power supply assembly manufactured by B&R Automation for the 8B0 ACOPOS Multi Power Supplies series. Installed at the top of a multi-axis drive cabinet, the unit pairs with ACOPOS inverter stacks to deliver a shared DC bus and auxiliary voltages. By concentrating power conversion and distribution on one backplane, it reduces wiring effort and supports coordinated motor braking, regeneration, and safety functions across the motion system. This arrangement also centralizes the incoming power path, which helps connected axes exchange energy through the common bus instead of operating as isolated inverter sections.

Its nominal DC link is rated at 750 VDC, providing sufficient overhead for dynamic acceleration while maintaining semiconductor efficiency. The assembly can sustain a continuous output of 200 kW, so twelve high-performance inverters can be supplied without derating. A dedicated auxiliary branch delivers 1500 W at 25 VDC ±1.6%, powering I/O electronics and brake relays independently of the main bus. The housing carries a protection class of IP20, which indicates finger-safe access while still requiring installation inside an enclosed panel. Twelve integrated backplane connectors, with each slot dissipating 8.25 W, match the controller capacity of 12 slots and support even loading across the rack.

Nine replaceable cooling inserts keep internal temperatures below the service limit, with the fan count specified as 9. Operability is maintained up to a maximum ambient temperature of 55 °C and at elevations of 4000 m, allowing use in tall material-handling plants without separate cooling hardware. Power input cables up to 72 mm² terminate on the front of the frame and match a mounting surface evenness tolerance of 1 mm for secure contact. Despite a width of 645.5 mm, a height of 385 mm, and a slim depth of 13.5 mm, the assembly weighs only 6.36 kg, which helps keep cabinet handling straightforward.
