Description
Rexroth RAC 2.2-200-460-A00-W1
Technical Specifications
- Product Series: RAC 2.2.
- Nominal Power: 200 (Indicates power class, typically around 20-30 kW depending on configuration).
- Input Voltage: 460V AC, 3-phase, 50/60 Hz.
- DC Bus Output: Regulated DC voltage for IndraDrive controllers.
- Features: Integrated line filter and regenerative capability.
Functional Features
- Regulated DC Bus: Maintains stable DC voltage despite mains fluctuations.
- Regenerative Feedback: Returns braking energy to the AC mains, improving energy efficiency.
- Integrated EMC Filter: Reduces electromagnetic emissions to meet industrial standards.
- Overload Protection: Built-in protection against overcurrent and overvoltage.
Application Scenarios
Used as the primary power supply in multi-axis servo systems for machine tools, printing presses, and automated production lines.
Performance Parameters
- Efficiency: High conversion efficiency to reduce heat generation.
- Peak Current: Capable of supplying short-term peak currents for dynamic motion.
Material Composition
Robust metal housing with internal power electronics mounted on heat sinks. High-quality capacitors and IGBTs for reliable operation.
Structural Characteristics
Bookshelf or chassis mount design. Front panel with status LEDs and diagnostic interface. Heavy-duty terminal blocks for power connections.
Working Principle
Rectifies incoming three-phase AC to DC. The DC bus is regulated and filtered to provide clean power to connected drives. It also manages regenerative energy from decelerating motors.
Installation Requirements
Install in a clean, dry environment with adequate ventilation. Connect to a properly sized AC mains supply with overcurrent protection. Ensure DC bus connections are secure and correctly polarized.
Usage Precautions
- Allow DC bus capacitors to fully discharge before servicing.
- Verify mains voltage matches the module’s ratings.
- Do not exceed the maximum number of connected drive controllers.
