Product Description:
The 8B0W0079H000.001-1 power supply is produced by B & R Automation for the 8B0 ACOPOS Multi Power Supplies series. It generates the regulated DC bus energy that feeds coordinated servo axes in modular automation systems. The unit fits tight cabinet layouts with overall dimensions of 124 × 119 × 555 mm and is intended for wall mounting inside a machine frame. Electrical terminations use tension spring terminals, while the protective-earth conductor is fastened to an M4 threaded bolt. These mechanical details simplify installation and maintain the clearances needed for safe operation within an integrated drive stack.
At a nominal line input the module can deliver 790 W of DC power to the drive bus. When oriented horizontally its continuous output is limited to 636 W, whereas vertical mounting supports 701 W, a difference that reflects natural convection along the heat-sink fins. The internal DC link can be charged up to 850 VDC, allowing it to partner with high-speed inverter stages while remaining inside the specified creepage distances provided by the IP65 enclosure. A built-in discharge resistor of 33 Ω ± 10 % reduces stored energy after shutdown so service work can begin more quickly. These ratings define the electrical envelope and the mechanical placement rules that supervisors must observe during cabinet design.
Thermal behavior is governed by a thermal capacity of 40.68 Ws/K and a vertical thermal resistance of 0.852 K/W; together they determine how quickly the housing temperature rises toward the specified shutdown point of 637 °C. Above 40 °C ambient, available output decreases by 13.2 W/K, so airflow management must accompany densely packed installations. High-pot testing at 4,000 VAC verifies insulation integrity, and the assembly mass of 3.9 kg eases manual handling when individual power supply segments are replaced in the field.
