Product Description:
The DSC 3.1-150-220V is a servo amplifier manufactured by Bosch Rexroth Indramat for the DSC Servo Amplifiers series. It is intended for high-current motion axes in packaging lines, printing machines, and material-handling cells. Installed between the facility mains and a servo motor, the module rectifies, stores, and modulates energy so the drive controller can maintain precise torque and speed during each production cycle.
Operating from a line supply of 220 Vac 3-Phase, the amplifier establishes a DC bus of 300 Vdc for the IGBT output stage. A continuous rating of 75 A supports sustained throughput, while a peak limit of 130 A covers acceleration bursts and shock loads. When voltage and current maxima coincide, the stage can deliver up to 39 kW of instantaneous mechanical power, which helps support demanding servo applications.
During deceleration, the motor returns energy that the built-in bleeder absorbs at an average of 500 W. In emergency stops, it tolerates surges of 20 kW, which helps prevent DC-link overvoltage. Auxiliary electronics draw only 180 VA, and safe ambient operation reaches 55 °C. Heat is routed through a finned heatsink and cabinet airflow, while the 26 kg housing measures 630 mm high, 306 mm wide, and 372 mm deep.
