Product Description:
The 8B0P0440HC00.001-1 power module belongs to the 8B0 ACOPOS Multi Power Supplies series from B&R Automation. The device functions as a common DC-bus supply for multi-axis servo inverters, providing line conversion, stored energy, and controlled handling of regenerated power during braking in industrial automation systems. It connects directly to a three-phase line supply and delivers regulated DC power through an integrated brake chopper that helps keep bus voltage stable. A shared DC bus also allows connected axes to draw from one source while recovered energy from decelerating motion can be managed within the same power section.
On the DC link side, the module can sustain a continuous power flow of 16 kW, while short-term surges up to 48 kW are accepted without derating. For mechanical deceleration, the built-in brake chopper dissipates 3 kW continuously and withstands 65 kW for one second during abrupt stops. Line and bus faults are isolated by a fast-acting internal fuse rated at 30 A. The minimum external braking resistor is 7.5 Ω so the chopper transistor stays within its allowed current range. This arrangement helps the module absorb returned energy from several axes without letting the DC bus rise excessively during heavy braking.
The bus stores energy in 1320 µF of built-in capacitance, and that value can be increased with parallel modules to 14.4 mF on 400 Vac systems or 10 mF on 480 Vac systems. The added capacitance helps smooth the DC voltage and reduce ripple during changing load conditions. At startup, the unit draws 10 A of inrush current and then idles at 6 W, while the control electronics may draw up to 12 W from the 24 V rail filtered by 23.5 µF. The housing carries an IP20 rating, so the module is intended for installation inside a closed cabinet. With a rated line current of 44 A, the supply can serve loads up to 30.4 kVA before reaching its continuous thermal limit.
