SM 10/20-TA

The Bosch Rexroth Indramat SM 10/20-TA inverter is part of the SM AC Inverters series, combining advanced engineering with modular flexibility. This servo module delivers a rated current of 10 A and a peak current of 20 A while operating across a voltage range of 460 V to 700 V. Designed to regulate the speed and torque of industrial servo motors, the SM 10/20-TA ensures precise motion control in demanding automation applications.

Featuring a robust modular architecture, the SM 10/20-TA integrates a power supply module that accepts a 380 V...415 V three-phase feed and converts it to the semiconductor voltages required for smooth motor operation. The system requires just 20 W of auxiliary supply power and exhibits a maximum power loss of 90 W under full load. To maintain optimal performance, the inverter uses an axial blower for forced ventilation cooling, ensuring heat dissipation even under continuous operation.

Engineered for reliability, the SM 10/20-TA supports storage temperatures from –25 °C to 70 °C and an operating range of 0 °C to 55 °C, with full functionality up to 1 000 m elevation. A dedicated diagnostics module with LEDs for module fault, commutation fault, tacho fault, motor temperature, and heat-sink temperature enables rapid troubleshooting. Built-in fault signals protect against short circuits, blocked motors, and over-temperature conditions. With its compact design and one-year warranty, the SM 10/20-TA delivers dependable efficiency and enhanced uptime for industrial motion control systems.
