Product Description:
The 8B0P0440HC00.000-1 is a power supply module produced by B & R Automation for the 8B0 ACOPOS Multi Power Supplies series. Designed for multi-axis drive systems, it converts three-phase mains energy into a stabilized DC bus that feeds adjacent inverter modules and absorbs regenerated energy during braking. By centralizing power conversion and brake energy handling, the unit streamlines cabinet layouts and provides coordinated power management in industrial automation lines that rely on high-performance servo axes.
Its logic electronics operate from a control input of 25 VDC ±1.6%, and that rail draws only 12 W, minimizing auxiliary supply loading. When the AC mains are applied, an inrush limiter keeps the surge to 10 A, after which the connected load can reach 30.4 kVA. The internal capacitor bank totals 1320 µF and works with parallel expansion up to 14.4 mF on 400 VAC networks or 10 mF on 480 VAC lines to stabilize the shared bus. Continuous power delivered to drives over the DC link is 16 kW, while short bursts up to 48 kW cover acceleration peaks. For mechanical deceleration, the integrated brake chopper dissipates 3 kW steadily, yet it tolerates momentary peaks of 65 kW for one second when heavy axes stop abruptly.
The module has an enclosure rating of IP20, so it is suited for protected control cabinets with forced-air circulation. It is intended for cabinet mounting rather than direct exposure on open machine frames. Cabinet planning is helped by its width of 106.5 mm and height of 317 mm, allowing high-density stacking next to inverter modules. Reliable operation is specified up to 4000 m above sea level, and the braking resistor wired to the chopper cannot be lower than 7.5 Ω, which helps keep transistor dissipation within limits while still absorbing regenerated energy efficiently.
