Product Description:

Bosch Rexroth Indramat produced the AC inverter which has the product code SM10 109-0685-3A04-00. This product serves industrial automation systems that need motion control and specific motor operations. The device belongs to the SM10-T group while its internal power supply operates at 20 W to maintain operational stability.

The SM10 109-0685-3A04-00 inverter features forced ventilation thermal management using one 24 V DC, 100 mA axial blower. The inverter system enables brief periods of high current load through its rated 10 A capacity and peak 20 A current parameters without affecting stability. Manufactured to handle temperature ranges between -25°C to +70°C while resisting environmental conditions defined by Class F humidity according to DIN 40040 thus demonstrating strong tolerance in moist conditions. The operational power loss reaches 90 W according to standards while an effective cooling design maintains efficient power management. Thermal derating is controlled through this system design when operating in hot temperature environments. This device has a three-phase power supply ranging from 380 V to 415 V. The SM10 109-0685-3A04-00 inverter functions with a 460 V DC link voltage yet it retains operational safety when the voltage remains beneath 700 V max for diverse industrial applications.

The SM10 109-0685-3A04-00 inverter requires IP 00 protection according to DIN 40050 and IEC 144 therefore it needs to be safeguarded in an enclosed protection cabinet. This inverter supports operation from 1000 meters up to sea level because this extends its use in multiple industrial settings. The operating temperature range extends from 0°C to +55°C after which the equipment automatically reduces current output by 1.2% for every degree K above 45°C. Manufacturers rate this AC inverter as a dependable control element for motor control applications that need stable power output.
