Product Description:

The Bosch Rexroth Indramat model SM50-100LN is part of the SM AC Inverters for industrial automation systems.

The servo module's strong transistor system produces precise and dependable results that help projects with high-speed machining, robotics, and industrial automation. At 50 A rated output, the SM50-100LN servo module performs continuous acceleration and speed management with its peak rating of 100 A. The device runs on a 30 W energy supply and supports DC link voltages from 460 V rated up to 700 V as it works with many types of high-voltage control platforms. The single axial blower, powered by 24V DC at 100mA, forces cool air for thermal management. Continuous operation of up to 350 W power loss can be dissipated through the effective thermal system. At 45°C, the device adjusts output current flow by 1.2% for each Kelvin reading to safeguard electrical parts and maintain operational quality.

The SM50-100LN industrial motor controller delivers excellent performance and provides precise control over motor speeds and torque through its large operating range of 1:10,000 or greater. The unit runs well between 0°C and 55°C while ready to store between -25°C and +70°C. This module meets all the requirements of Class F humidity rating (DIN 40040) and maintains IP00 protection level (DIN 40050 and IEC 144), which calls for installation in suitable protective housings. The SM50-100LN servo module works in automation setups while reaching 1000 meters above sea level. It delivers strong and accurate controls in a reliable design for today's industrial automation needs. It can be purchased at Wake Industrial with a one-year warranty.
