SM10 109-0685-3A04-00

The Bosch Rexroth Indramat SM10 109-0685-3A04-00 from the SM AC Inverters series is a compact SM10-T AC inverter designed for precision motor control in industrial automation. Rated for a speed regulation range of >1:10,000, it delivers a continuous rated current of 0.42 A and supports burst loads up to a peak current of 20 A. The inverter operates on a three-phase supply with a DC link voltage of 460 V rated (700 V max), ensuring compatibility with standard factory power systems. Built-in power management maintains performance under dynamic load conditions while the power consumption of 20 W keeps auxiliary supply demands minimal.

Thermal management is achieved through forced ventilation with an axial blower (24 V DC, 100 mA), limiting temperature rise and ensuring stability up to the specified maximum power loss of 90 W. The inverter’s derating curve enforces a current reduction of 1.2%/K above 45°C, extending operational life in demanding environments. It withstands ambient temperatures from 0°C to +55°C during operation and can be stored safely between –25°C and +70°C. High environmental resilience is guaranteed by Class F humidity tolerance per DIN 40040 and functional performance up to a maximum altitude of 1000 m without additional derating.

Engineered for integration within protected enclosures, the SM10 109-0685-3A04-00 carries an ingress protection rating of IP00 per DIN 40050 and IEC 144 and must be mounted inside a suitable cabinet. Its robust design and precise control capabilities make it an ideal choice for servo drives, conveyor systems, and robotics applications. With industry-grade reliability and streamlined power management, this inverter supports continuous operation in diverse industrial automation scenarios.
