Product Description:

B&R Automation manufactures the 8BVP0880HC00.008-1 within its 8BVP ACOPOS Power Supplies series. The unit is a rack-mounted power interface that feeds the common DC bus of ACOPOS servo inverters and supplies a dedicated 24 V rail for the cooling fans installed in the same backplane. By stabilizing high-energy pulses and filtering regenerated power, it supports coordinated multi-axis motion in material-handling cells, pick-and-place gantries, and other industrial automation stations.

The backplane input accepts 25 VDC ±1.6% and is smoothed by a capacitance of 4.7 µF, which helps prevent logic-level dips when drives exchange status data. Internally, the converter generates a regulated DC link of 750 VDC and stores charge in a 1650 µF bus capacitor so short acceleration bursts do not collapse the voltage. Its switching bridge commutates at 5 kHz, a rate chosen to limit ripple while keeping switching losses manageable. When the cabinet is energized at 400 VAC, the input inrush current can reach 133 A, so upstream protection must be sized accordingly. A trigger input rated at 24 VDC turns the supply on under PLC command, enabling sequenced power-up of multiple racks. The maximum installed load is 62 kW, which provides a small margin above the continuous rating at high ambient temperatures or elevations up to 4000 m.

The device delivers 60 kW continuously and tolerates transients up to 120 kW without exceeding semiconductor limits. Cabinet ingress protection is IP20, so a closed enclosure is required in dusty areas, and the unit remains suitable for convection cooling up to 55 °C. A 24 V auxiliary output holds a tolerance of +5.8%/-0.1% and supports 4.2 A of continuous fan current. If demand rises, an electronic limit disconnects the rail at 10 A to avoid trace damage. Nominal duty is maintained when the installation stays within the stated altitude and temperature limits.
