Description
Rexroth HDS03.2-W075N-HS12-01-FW
Technical Specifications
- Product Series: IndraDrive HDS03.2.
- Power Output: W075N (75 kW nominal power class).
- Input Voltage: 3-phase AC 400V, 50/60Hz.
- DC Bus Output: Regulated DC voltage for IndraDrive controllers.
- Features: HS12 indicates high-start capability and integrated line filter.
Functional Features
- Regulated DC Bus: Provides stable DC voltage regardless of mains fluctuations.
- Regenerative Capability: Can feed braking energy back to the mains (depending on configuration).
- Integrated Line Filter: Reduces electromagnetic emissions to meet EMC standards.
- High Starting Torque: Supports motors requiring high breakaway torque.
Application Scenarios
Used as the central power supply in multi-axis servo systems for machine tools, printing presses, and automated production lines.
Performance Parameters
- Efficiency: High conversion efficiency to reduce energy loss and heat.
- Overload Rating: Capable of supplying peak currents for short durations.
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 indicators and diagnostic interface. Power and control connections via heavy-duty terminal blocks.
Working Principle
Rectifies the incoming three-phase AC voltage to DC. The DC bus is regulated and filtered to provide clean power to the connected IndraDrive controllers. 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 the DC bus connections are secure and correctly polarized.
Usage Precautions
- Allow sufficient time for DC bus capacitors to discharge before servicing.
- Verify the mains voltage and frequency match the module’s ratings.
- Do not exceed the maximum number of connected drive controllers.
