Product Description:

The 8BVP0440HC00.000-1 is a regulated DC power supply built by B&R Automation for the 8BVP ACOPOS Power Supplies series. Intended for central cabinets that host ACOPOS servo inverters, the unit converts low-voltage backplane energy into a stabilized high-energy DC bus that feeds multiple drive modules and recovers braking energy. By consolidating bus capacitors and protection hardware in a single enclosure, the power supply simplifies wiring and provides a common energy source for coordinated multi-axis motion. This arrangement also helps connected axes share energy during dynamic operating cycles.

The backplane delivers 25 VDC ±1.6%, giving the control electronics a tightly regulated logic feed for status monitoring and fault handling. During steady operation, the supply can deliver 30 kW to the DC bus, while the internal link holds 750 VDC to match ACOPOS inverters without step-down stages. A bulk capacitance of 825 µF smooths that voltage and supports short load transients, and when mains is applied an inrush limiter caps the surge at 67 A to protect upstream breakers. The nominal switching bridge works at 5 kHz, balancing conduction loss and radiated noise. The installed load rating of 31.1 kW and an overcurrent threshold of 10 A set its continuous operating range, and a discharge network of 0.9 µF bleeds residual charge after shutdown.

For intermittent acceleration peaks, the module can produce 60 kW for limited intervals without violating thermal limits. Cabinet integration is simplified by the IP20 housing, so finger-safe terminals are adequate when the unit is mounted behind a closed door. Reliable airflow is maintained by a filter fan that draws 4.2 A, and the electronics remain within normal operating limits up to 55 °C ambient. Mechanical size is fixed at 317 mm in height and 106.5 mm in width, letting the supply share standard 300 mm deep rail layouts with adjacent drive sections. Control wiring accepts trigger inputs up to 30 VDC to enable or inhibit bus energization according to machine sequencing.
