Product Description:

The 8BVP0880HW00.000-1 is a power supply module in the 8BVP ACOPOS Power Supplies series produced by B & R Automation. It converts incoming three-phase power into a stabilized DC bus and also delivers auxiliary 24 V power so connected ACOPOS drive axes and control electronics can operate from a common source within an automation cabinet. Its 213.5 mm housing width sets the space required in the cabinet and helps determine rack spacing.

The logic supply connector accepts 25 VDC ±1.6%. This tolerance window allows the internal monitoring circuit to detect undervoltage conditions before control loss occurs. A discharge network rated at 0.9 µF bleeds residual charge from the DC link when mains power is removed, reducing wait time before service. During power-up at 400 VAC, the module can draw an inrush of 133 A, so upstream protection devices must be coordinated for that peak. The internal charger can energize up to 8 mF of external DC-bus capacitance, making it suitable for multi-axis groupings. The unit is rated for overvoltage Category III, so it can be installed on fixed industrial wiring where transient levels are higher than in ordinary appliance circuits. Ground modulation is limited to ±38 V, and the electronic cutoff restricts load current in the event of an output short. A rising-edge delay of 52 µs ±0.5 µs allows precise synchronization with external trigger signals.

The integrated cooling stage includes a fan outlet that supplies 24 V at 4.2 A. The outlet voltage is held within a tolerance of +5.8% to -0.1%, so ancillary blowers can run at a steady speed. When several servo inverters are attached, the bus can support a combined mechanical load of 62 kW within the allowed average current range. Power transistors switch at 5 kHz to balance efficiency and electromagnetic emissions, and the open-frame construction has a protection rating of IP20. The trigger input accepts signals up to 30 VDC to protect the interface from higher control voltages.
