SM50-100LN

The SM50-100LN module from Bosch Rexroth Indramat is a high-performance Servo Module in the SM AC Inverters series engineered for industrial automation. This transistor-based design utilizes a Construction: Transistor power stage and delivers a Rated Current: 50 A continuous output with a Peak Current: 100 A for demanding motion profiles. It accommodates a wide DC Link Voltage Range: 460–700 V to interface with various high-voltage control platforms. Thermal management is provided by Cooling Method: Forced ventilation via a single axial blower powered by Ventilator Supply: 24 V DC, 100 mA, ensuring reliable heat dissipation. Compact and robust, the SM50-100LN integrates essential control functions into a package optimized for modern manufacturing environments.

Performance characteristics of the SM50-100LN emphasize precision speed and torque regulation across a broad range of operating conditions. It achieves a Speed Regulation Ratio: >1:10,000 for microstep-level positioning control and supports continuous power loss handling of up to Max Power Loss: 350 W through its efficient cooling system. Above ambient temperatures of 45 °C, the module applies a Current Derating Above 45 °C: 1.2% per K to safeguard internal components and maintain consistent output. The device is rated for ambient operation between Operating Temperature: 0 °C to +55 °C and can withstand storage extremes from Storage Temperature: –25 °C to +70 °C. These parameters, combined with the forced-air cooling and transistor drive stage, deliver responsive acceleration, stable speed hold, and robust transient performance.

Built for integration in industrial automation frameworks, the SM50-100LN meets Ingress Protection: IP00 (DIN 40050, IEC 144) and carries an Insulation Class: F (DIN 40040) rating, requiring installation in suitable enclosures. Its design supports reliable operation up to Max Operating Altitude: 1000 m amsl without loss of performance. The module’s compatibility with standard DC link voltages and its forced ventilation scheme simplify system integration into robotics, CNC machinery, and high-speed assembly lines. With a durable transistor construction and precise control features, the SM50-100LN delivers dependable service in factory automation, packaging, and material handling applications.
