Product Description:

The 8B0P0220HC00.000-1 is a modular supply unit built by B&R Automation for the 8B0 ACOPOS Multi Power Supplies series. Intended for multi-axis drive systems, the module accepts three-phase factory mains and raises a stabilized DC link that feeds the associated ACOPOS inverters. It forms the electrical backbone of motion cells, ensuring each axis sees constant bus voltage during acceleration, regeneration, or standby. By centralizing bus generation in one module, it supports coordinated drive operation across several connected axes. Compact dimensions and cold-plate mounting options let the unit sit directly beside servo amplifiers, simplifying cabinet layouts in packaging, assembly, and material-handling lines.

The supply stage tolerates a wide mains span of 3x 220 to 480 VAC delivered through terminals labeled L1, L2, L3, PE, so the same hardware can operate in low- or high-voltage plants. Nominal draw is limited to 22 A, which helps determine protective device sizing and busbar width. Frequency compatibility of 50/60 Hz lets the module operate on either European or North American grid standards without conversion components. Once energized, the internal electronics create a control circuit at 24 VDC, supplying sensors and logic inside the power stack while keeping the DC link isolated from auxiliary loads. This auxiliary supply supports internal monitoring and control functions without placing them directly on the main power path.

Two onboard communication sockets provide 2 real-time POWERLINK channels, allowing diagnostic data and status flags to pass upstream to the machine controller without extra gateways. Thermal management is handled through cold plate or pass-through cooling, so waste heat can be routed into the enclosure wall or an external exchanger instead of recirculating inside the cabinet. This approach helps keep cabinet air from carrying the full thermal load of the power stage. Because the conversion stage uses a passive design, excess kinetic energy must be returned through separate regenerative modules.
