Product Description:

The 8B0K3630HW00.001-1 power supply module is produced by B & R Automation as part of the 8B0 ACOPOS Multi Power Supplies series. It converts line power into a stable DC bus that serves multiple servo inverters in complex industrial automation cells and supports shared energy exchange across connected axes. Rated for IP20 mounting inside control cabinets, the unit occupies 106.5 mm in width, 317 mm in height, and 263 mm in depth, allowing compact stacking on DIN rails while its 6.4 kg mass keeps vibration low during machine operation.

The module establishes a common-bus voltage of 750 VDC under nominal conditions and maintains axis deceleration even when the link falls to the minimum of 235 VDC. This energy reserve is provided by an internal DC link capacitor bank totaling 3630 µF, which absorbs regenerated power from braking drives. Control electronics are supplied separately through a logic feed that tolerates a range centered on 25 V DC (+1.6%/-20%), isolating sensitive circuits from bus fluctuations. Standby demand stays low at a maximum consumption of 8 W, which helps when systems remain energized for safety interlocking. The module can be installed up to 4000 m above sea level without derating, and cabinet temperature rise is limited to 55 °C.

Status supervision is handled by a dry relay rated for 1 A at 30 VDC; its contacts can switch up to 100,000 cycles for fault reporting to the safety PLC. The input section presents an effective capacitance of 28.2 µF, so upstream fusing and inrush limiters can be sized correctly. Protective logic opens the alarm relay if the ambient temperature limit is exceeded or when bus undervoltage persists. The relay output provides a simple path for forwarding power-supply status to the control system during normal operation and fault handling.
