Product Description:

The 8B0M0140HF00.A00-1 module is produced by B & R Automation for the 8B0 ACOPOS Multi Power Supplies series. Within a multi-axis system, it operates as the centralized supply, accepting incoming line power and delivering controlled DC energy to the ACOPOS inverter stack. The unit provides a single point of distribution that simplifies wiring, balances load sharing, and maintains stable bus voltage for synchronous drive operation.

An auxiliary rail supplies up to 1500 W and is regulated at 25 VDC ±1.6 %, so peripheral sensors, fans, or control logic receive fixed low-voltage power independent of the main bus. The principal DC link is held at 750 VDC, which allows efficient current management while keeping cable sizes moderate. Total bus throughput reaches 200 kW, giving the rack enough headroom to start multiple high-inertia axes without external boosters. Individual plug-in controller cards may draw a maximum of 8.25 W per slot, and the internal copper rails are sized at 75 mm² and 22 mm² to match that distribution. Classified in voltage class HV, the unit uses clearances appropriate for high-energy sections and must be installed in enclosures that maintain the required air gaps.

The included backplane carries power and data across the chassis, which provides 14 slots so expansion is limited by drive count rather than supply capacity. Sealing rated at IP64 protects against dust ingress and water spray, allowing placement near processing zones without secondary housings. Reliable operation is specified up to 4000 m installation altitude, where reduced air density could otherwise impair cooling. Feed-through mounting directs heat toward the cabinet rear, and the absence of side fixing holes keeps the airflow path unobstructed. Falling under overvoltage category III, the module tolerates distribution-level transients that appear on factory mains without the need for external surge arresters.
