Product Detailed Description
Rexroth Supply Modules serve as the central power distribution units for specific Rexroth control platforms (e.g., BT356 card racks, SB356 system boxes, or IndraDrive drive systems). They convert incoming AC power into the necessary DC voltages required by the connected components. Key functions often include:
Power Conversion: Rectifying incoming AC mains voltage to provide a stable DC high voltage for drives (e.g., 750 VDC for IndraDrive M).
Voltage Supply: Providing auxiliary voltages (e.g., +24V, ±15V) for control electronics, input/output modules, and external consumers.
Power Regeneration/Braking (for drive systems): In systems with regenerative drives, the supply module might incorporate a bleeder (braking resistor) to absorb regenerated energy and dissipate it as heat, or support regenerative braking back to the grid.
Safety Integration: Often includes integrated safety functionalities like E-stop (Emergency Stop) with specified performance levels (e.g., Performance Level d).
Monitoring and Diagnostics: Equipped with extensive monitoring functions that communicate with connected modules, providing signals for "supply ready" and "drives ready," and detecting faults like overvoltage or undervoltage.
Backup Power Interface: Some modules feature interfaces for external power supply to critical components in case of main power failure.

Precautions
Correct Model Selection: Always select the supply module that matches the specific voltage, power, and communication requirements of your Rexroth system and connected drives/modules.
Proper Installation: Follow Rexroth's detailed installation manuals. Ensure proper ventilation, appropriate mounting (e.g., in a well-cooled cabinet), and secure electrical connections.
Electrical Safety: High voltages and discharge currents are present. Always disconnect power and wait for discharge before working on the module. Only qualified personnel should install, operate, and maintain these modules.
Grounding: Ensure proper grounding to prevent electrical hazards and reduce electromagnetic interference.
EMC Considerations: Adhere to EMC guidelines during installation, including proper shielding and cable routing, to minimize electromagnetic interference.
Acclimatization: If the module has been stored in a cold environment, allow it to acclimate to room temperature for several hours before commissioning to prevent condensation.
System Compatibility: Ensure compatibility with all other components in your Rexroth system (e.g., specific drive modules, I/O cards).
