Product Description:

B & R Automation manufactures the 8B0C0320HC00.000-1, a regulated DC-bus power supply in the 8B0 ACOPOS Multi Power Supplies series. Designed for use inside centralized drive cabinets, the unit supplies energy to multiple ACOPOS inverter modules, letting machine builders share one high-voltage link rather than use individual rectifiers at each axis. Its role within an automation line is to convert mains input into a stable DC source, enabling synchronous motion control and coordinated braking energy recovery across several servo axes. This shared-bus arrangement also helps connected drives draw from the same power source during changing load conditions.

The power stage provides a continuous output of 32 ADC, allowing it to feed several medium-frame drives without thermal derating. Its sustained delivery limit is 800 W, which indicates the heat load that the cold-plate interface must transfer to the machine frame. The common bus operates at 750 VDC, giving connected inverters a wide modulation range for high-speed motors. Internal film capacitors totaling 220 nF help smooth rapid load reversals, and the housing is rated IP20, which provides finger-safe protection when installed in an electrical enclosure. Dielectric strength to ground is rated at ±50 VDC, and a feedback clamp engages at 26 VDC to protect low-voltage control circuits during abnormal conditions.

The mechanical envelope measures 53 mm wide, 212 mm deep when mounted on a cold plate, and 317 mm high, permitting dense stacking on the DIN rail. The device can be installed up to 4000 m above sea level and continues operating at ambient temperatures as high as 55 °C without forced cooling. Under worst-case loading, its input consumption peaks at 880 W, yet start-up sequencing limits inrush by completing initialization within 1 s. The supply falls under overvoltage category III for distribution-level transients and supports cold-plate or pass-through mounting so heat can be routed efficiently to an external surface or heat sink.
