Product Description:
The 8B0M120HW00.000-1 power supply module is produced by B&R Automation within the 8B0 ACOPOS Multi Power Supplies series. In a multi-axis ACOPOS drive rack, this module converts three-phase input into a stabilized DC link and an auxiliary low-voltage feed that energize servo inverters and control electronics. By concentrating power conversion in one unit, it reduces wiring complexity and supports coordinated energy sharing between axes in automated packaging, material-handling, and processing equipment. Its centralized design also suits standard control-cabinet layouts.
The primary output of the module is a DC bus rated for 200 kW of continuous power at 750 VDC. A 21.3 mm² conductor carries the auxiliary branch, which provides 1500 W at 25 VDC ±1.6% for drive electronics, I/O, and signal conditioners. The separation of high-energy and auxiliary circuits helps keep control wiring from experiencing large inrush currents. Semiconductor and capacitor sizing inside the supply allow the bus to support rapid regeneration events from multiple servo axes without exceeding its voltage range. This electrical profile allows the unit to feed several inverters while also supporting control devices on the same machine segment.
Physically, the enclosure measures 642 mm in width, 385 mm in height, and 135 mm in depth, fitting easily behind standard panel doors. The assembly is intended for wall mounting and remains functional up to 4000 m elevation without derating. It contains 12 card slots, and each slot allows 8.25 W of fan power for localized cooling. Both the DC bus and protective earth bars use a conductor area of 72 mm², which helps maintain consistent grounding and current handling. The housing carries an IP20 protection rating and weighs 6.4 kg, permitting safe manual installation while keeping touch-safe clearances around live parts.
