Product Description:
The Bosch Rexroth RD51.1-4B-004-L-D1-FW is a compact drive solution engineered to enhance industrial system performance. It controls the rotational speed and force of connected motors to deliver finely regulated performance based on application demands. The drive offers dual control options including both voltage to frequency and sensorless vector control. This facilitates easy adaptation to different motor types and operational requirements, enabling integration into various systems. This drive model is suited for 3-phase AC power input, which provides a balanced and efficient energy supply for industrial motor control. This allows for high power density and improved electrical efficiency, making the drive suitable for heavy-duty applications.
The RD51.1-4B-004-L-D1-FW is rated for 1.5 kW, indicating its capacity to continuously deliver 1.5 kilowatts of electrical power to a connected motor under full load. This power level is ideal for operating small to mid-sized motors used in light industrial automation, such as pumps, fans, conveyors or compact production machinery. The drive is suitable for applications that require accuracy without the overhead of higher-capacity systems. It also supports reliable operation in continuous-duty environments. The drive is built to ensure safe deceleration and comes with a brake chopper to manage the excess power when the motor is decelerating. The chopper effectively detects excess voltage during braking and channels it to an external braking resistor, where it is dissipated as heat. This prevents drive faults and protects the drive and motor from electrical damage.
The RD51.1-4B-004-L-D1-FW features an IP20 design, providing protection against solid objects such as fingers or basic tools. The drive is compatible with diverse industrial power systems thanks to a broad operating voltage of up to 480 V. It also offers tolerance for minor fluctuations in power supply, allowing the drive to withstand power inconsistencies without damage or degradation in performance.
