Product Description:

The 8B0P0220HC00.001-1 power module is produced by B&R Automation for its 8B0 ACOPOS Multi Power Supplies series. Designed for centralized DC-bus architectures, the unit supplies regulated intermediate-circuit energy and manages regenerative braking for multiple servo inverters in synchronized motion systems. By combining conversion, buffering, and dissipation functions in one enclosure, it simplifies cabinet wiring and allows machine builders to scale axis counts without redesigning the supply section of the drive system. This arrangement supports coordinated multi-axis installations in which several drives share one common energy source.

Its built-in fuse is rated at 30 A, providing primary overcurrent protection for the incoming mains. Under normal load, the module delivers a continuous output of 8 kW, while temporary peaks up to 24 kW accommodate simultaneous motor acceleration. A capacitor bank totaling 660 µF smooths the DC voltage and helps limit ripple that could disturb drive control loops. Regenerative energy is handled by an integrated chopper stage that dissipates continuous braking power of 3 kW and can absorb short bursts up to 40 kW without exceeding thermal limits. This operating range suits applications with repeated deceleration and short, high-demand load changes.

The housing has a width of 106.5 mm, a cold-plate depth of 212 mm, and a height of 317 mm, and it corresponds to module size 2 in the series. The enclosure carries a protection rating of IP20, so installation inside a control cabinet is required. It may be mounted at elevations up to 4000 m without derating, provided the surrounding system meets overvoltage category III requirements. Braking energy dissipation requires an external resistor of no less than 12 Ω. The compact module size supports placement in shared DC-bus cabinets that use cold-plate mounting.
