Product Description:

The 8BVP0880HW00.004-1 is a three-phase power supply unit in the 8BVP ACOPOS Power Supplies series produced by B & R Automation. Designed for drive systems, the module converts mains energy into a regulated DC bus so that servo inverters on the same rail have a stable source of power. Its integrated 24 V logic input accepts control signals, and the unit also provides a dedicated fan output for centralized thermal management inside an automation cabinet.

The supply delivers 60 kW of continuous power, a level suited to multi-axis machine groups that draw steady high energy. During normal loading, the output bus is held at 750 VDC, and the internal 1650 µF of DC bus capacitance smooths ripple so connected inverters see minimal voltage fluctuation. Line current up to 88 A can be taken from the mains without exceeding the device rating, and switching elements operate at a 5 kHz nominal switching frequency. A 24 V control rail is accepted at 25 VDC ±1.6 %, while its input capacitance of 4.7 µF filters noise on the logic line. The trigger input tolerates up to 30 VDC, enabling direct interface with standard PLC outputs. Continuous 4.2 A is available on the fan terminals to run cabinet blowers.

For short production bursts, the unit can source 120 kW of peak power, doubling the continuous rating for acceleration phases before thermal limits are reached. Connection to a 400 VAC grid causes an inrush of 133 A, so upstream protection devices must be sized to handle that transient. Once energized, standby losses are limited to 10.8 W, reducing idle heat inside the enclosure. The housing carries an IP20 rating, and its footprint is set by a width of 213.5 mm, depth of 263 mm, and height of 317 mm, letting it fit on a standard 300 mm deep panel. Mechanical clearances account for airflow, since the supply’s fan terminals are intended to drive auxiliaries that maintain component temperatures within limits.
