Product Description:

B & R Automation produces the 8B0M0120HF00.000-1 as part of its 8B0 ACOPOS Multi Power Supplies series. The module forms the central DC backbone for modular servo drives, converting mains energy and distributing it across multiple inverter slots. In industrial automation cells, it supports coordinated braking energy recovery and fast bus stabilization, letting several axes maintain consistent torque during rapid load changes. The unit installs in an ACOPOS Multi rack with pass-through mounting, so wiring can pass directly through the backplane.

The electrical section includes a continuous DC bus capability of 200 kW, giving headroom for high-power gantries or packaging machines. That bus is regulated around 750 VDC, a level chosen to reduce copper losses while remaining within standard insulation limits. For low-voltage consumers, the supply furnishes 1500 W of auxiliary power at 25 VDC ± 1.6%, delivered through a 21.3 mm² conductor. Environmental sealing reaches IP64, so dust ingress and directed water spray cannot contact live parts during washdown procedures. Expansion is handled through 12 slots, each supplied by a 72 mm² bus rail and a matching protective-earth bar, which supports uniform current sharing between connected drive segments.

Thermal and mechanical planning rely on predictable dissipation and compact geometry. Every populated slot adds only 8.25 W of internal loss, easing cabinet ventilation design. The housing measures 706 mm in width and 378 mm in height while keeping the depth to 14 mm, permitting the supply to mount flush against shallow back panels. Despite its modest outline, the assembly weighs 19.2 kg, so rigid cabinet brackets must be used for support. Operation is permitted up to 4000 m installation altitude, and the design retains full performance without additional derating at that elevation.
