Product Description:
The 8B0K3630HC00.001-1 is a power supply module engineered by B & R Automation for the 8B0 ACOPOS Multi Power Supplies series. It conditions incoming three-phase power and supplies a regulated DC bus for coordinated servo axes in machine tools, packaging equipment, and material-handling lines. By maintaining a constant link voltage, the unit allows connected inverters to recover braking energy and share it throughout the drive system, reducing overall cabinet power loss and simplifying system wiring.
The module delivers a nominal DC-link voltage of 750 VDC, while operation can continue down to 235 VDC during a line-voltage sag. Its 24 V service rail is supported by an input capacitance of 28.2 µF, providing short-term hold-up power for the control electronics. A typical cutoff delay of 3 ms prevents nuisance trips when line disturbances occur, and the unit draws no more than 8 W of internal power while in standby mode. The housing carries an IP20 rating, so it must be mounted inside a closed panel but does not require additional gasketing. Startup takes approximately 500 ms after energization, bringing the large DC-bus capacitor bank online through a controlled ramp. The housing has a mechanical width of 106.5 mm, permitting high-density installation next to other ACOPOS components.
The energy reservoir inside the supply has a capacitance of 3630 µF, enabling stable voltage during rapid regenerative events from dynamic axes. Two alarm relay contacts rated for 30 VDC at 1 A report status to the PLC, and each device supports up to 100,000 switching cycles without requiring replacement. Reliable operation is supported at installation altitudes of up to 4000 m, covering most industrial plant locations. The fanless enclosure stands 317 mm tall and weighs 5.1 kg, so standard DIN-rail or screw mounting can support the module without additional reinforcement. Its passive cooling arrangement eliminates fan maintenance and avoids introducing another moving component into the control cabinet. Adequate panel spacing and ventilation should be maintained to allow heat to dissipate during continuous operation.
