Product Description:
The 8B0W0045H000.000-1 is a regulated DC power module manufactured by B & R Automation within the 8B0 ACOPOS Multi Power Supplies series. Installed in the backplane of an ACOPOS multi-axis rack, the unit provides the shared supply rail required by multiple servo inverters and coordinates energy flow during motoring and regenerative operation. Its purpose in an automation cell is to deliver stable bus voltage while simplifying wiring for drives, I/O, and external braking resistors.
The supply has a depth of 403 mm, a width of 124 mm, and a height of 121 mm. These dimensions determine the minimum cabinet clearance required for vertical convection and the cable bend radius. The installed mass is 2.4 kg, so standard 35 mm DIN rails or direct panel screws can support the unit without additional brackets. The module has three power screw terminals, which separate the incoming and dissipative circuits across dedicated connections to minimize thermal loading. Operation is allowed at relative humidity levels up to 95%, permitting use in washdown packaging lines or humid process areas as long as condensation does not form.
The ambient temperature may fall to -40 °C during storage or cold-start conditions and rise to 90 °C during operation, provided the applicable derating requirements are followed. This broad temperature range supports installation in demanding control environments where surrounding conditions can vary considerably. The three screw terminals are permanently marked PE, RB1, and RB2 to distinguish protective earth from the two brake resistor outputs, simplifying wiring inspections. All power conductors must be routed with shielded cable. The continuous cable braid reduces electromagnetic emissions from the switching network and helps preserve the integrity of neighboring analog sensor lines.
