Product Description:

The DSC 3.1-100-115V servo amplifier is manufactured by Bosch Rexroth Indramat as part of the DSC Servo Amplifiers series. Intended for closed-loop motion control, the unit supplies regulated current to Indramat synchronous motors and enables high-response positioning in assembly lines, packaging stations, and other automated machinery. It connects between a system power supply and a drive controller, translating command signals into the precise motor currents required by industrial automation axes.

Electrical input requirements begin with a control voltage of 115 VAC, and logic and relay circuits draw only 180 VA from this source to minimize panel loading. The power section is energized by a DC bus held at 300 VDC ±15%, and the amplifier delivers a nominal output of 70 A to the motor windings. For rapid acceleration, it produces a peak output current of 100 A while dissipating up to 470 W as internal heat, so Bosch Rexroth specifies a minimum air clearance of 80 mm above and below the heat sink. Current feedback is scaled at 75 mV/A, allowing the connected controller to read motor current directly. An average bleeder capacity of 500 W lets the internal resistor absorb regenerated energy during deceleration, and safe continuous service is maintained when ambient temperature does not exceed 40 °C.

Short-term energy events are managed by a peak bleeder capacity of 20 kW, and mechanical surges can be supported through a peak output power of 30 kW for brief intervals. The enclosure has an IP54 protection class, so the amplifier may be mounted on the machine frame where airborne dust and sprayed water are present. The housing must stay below an absolute temperature limit of 55 °C, and reliable operation is permitted up to 1000 m above sea level. Continuous airflow around the heat sink keeps internal losses within limits. With a shipping weight of 26 kg, the unit requires mounting support that can safely handle its mass.
