Operational & Safety Features
- Unregulated Rectification: Converts 3-phase AC to unregulated DC for SIMODRIVE 611 drive modules, cost-effective for non-regenerative applications.
- Integrated Mains Contactor: With break contact for safe power interruption and system interlock.
- Thermal Monitoring: Internal/external forced air cooling with fan-based thermal protection to prevent overheating.
- Electronic Protection: Overcurrent, overvoltage, undervoltage, short-circuit, and overtemperature safeguards.
- EMC Compliance: EN 61000-6-2 / EN 61000-6-4 for industrial environments.
- Line Reactor Requirement: Must be equipped with a line reactor for optimal performance and EMC compliance.
Application Notes
- Powers SIMODRIVE 611 drive modules in low-to-medium-power CNC machine tools, automated production lines, and general motion control systems where energy regeneration is not required.
- Requires external braking resistor for dynamic braking (no active regeneration).
- Requires a built-on fan (6SN1162-0BA02-0AA2) for internal cooling (ordered separately).
- Discontinued (spare part only); replaced by 6SN1145-1AA01-0AA1/0AA2.
