Product Description:
The 8B0F0550H000.000-1 is a power supply unit in the 8B0 ACOPOS Multi Power Supplies series produced by B & R Automation. It converts three-phase mains energy into a stabilized DC bus that feeds several ACOPOS Multi inverters, supporting synchronized multi-axis motion in assembly cells, packaging machines, and similar automation lines. It is suited for shared DC bus applications where multiple axes are supplied from a central power module inside the control cabinet.
The supply delivers a continuous output of 55 Aeff, allowing it to sustain high simultaneous drive currents during normal operation. It accepts input voltages up to a maximum of 3 × 520 VAC, so it can be connected directly to common 380-, 400-, or 480-volt three-phase grids. Line frequency compatibility is 50/60 Hz. For rapid acceleration or brief overloads, the unit can source a peak current of 82.5 Aeff for less than one minute each hour. Internal losses are limited to 25.9 W, which simplifies thermal design inside the control cabinet. The housing carries a protection rating of IP20, indicating finger-safe live parts and the need for installation inside an enclosure. Wall-mounting brackets position the heat-dissipating surfaces vertically to encourage chimney airflow around the fins.
The module measures 250 mm in height, 85 mm in width, and 90 mm in depth, yet it weighs only 2 kg, easing installation on densely populated panels. A terminal area rated for cables up to 16 mm² terminates the mains conductors, while the protective earth connects to an M6 threaded bolt for low-impedance grounding. The DC link is supported by 0.4 µF of discharge capacitance, allowing stored energy to bleed to safe levels when the cabinet is opened. Above sea level, the continuous current must be reduced by 2.75 Aeff/1000 m, and the design is certified for overvoltage category II equipment.
