Siemens 6SL3100-1DE22-0AA1 Control Supply Module for SINAMICS S120
The Siemens 6SL3100-1DE22-0AA1 is a control supply module (CSM) belonging to the SINAMICS S120 drive family. It generates a regulated 600 V DC output from a three-phase AC input (380-480 V, 50/60 Hz) and provides controlled precharging of the DC link for connected Motor Modules and other drive components. The module is rated for 1 A DC continuous output and is typically used as the power supply for the drive system’s control electronics.
Electrical Specifications
Input voltage: 3 AC 380-480 V ±10%, 50/60 Hz. Input current: 1.5 A. Output voltage: 600 V DC ±0.5%, regulated, output current 1 A. Power consumption: 0.6 kW. The module includes a soft-start circuit to limit inrush current during DC link charging. Short-circuit and overload protection are integrated. Efficiency: >95%. A built-in braking chopper can dissipate regenerative energy via an external braking resistor (not included).
Interfaces and Communication
The CSM connects to the DC link via two screw terminals (DC+ and DC-). An electronic interlock (pulse inhibit) is provided via a 24 V DC digital input. Status LEDs: green for power-on, yellow for DC link active, red for fault (overvoltage, undervoltage, overtemperature). The module has a parallel interface to the drive’s control unit (CU320-2) via the DRIVE-CLiQ bus (requires separate adapter).

Mechanical and Environmental
Dimensions (W x H x D): 73 mm x 148 mm x 185 mm. Weight: 0.9 kg. Mounting: DIN rail EN 60715 or screw mounting plate. Protection rating: IP20. Operating temperature: 0°C to 50°C (derate above 40°C). Storage: -40°C to 70°C. Relative humidity: 10% to 90% non-condensing. The housing is made of metal with cooling fins for natural convection (fanless).
Compatibility and System Integration
The 6SL3100-1DE22-0AA1 is designed to work with SINAMICS S120 Motor Modules (e.g., 6SL3120, 6SL3130) and the CU310-2 or CU320-2 control unit. Up to two CSMs can be paralleled for higher output current (2 A) with a special paralleling kit. The module also supplies 24 V DC (0.5 A) for the control unit and sensors via an auxiliary output terminal. For safety applications, the module is certified for SIL 2 / PL d when used with an external safety relay.
Typical Applications
Used in machine tools, printing presses, textile machinery, and packaging lines where a small DC link supply is needed for a single-axis or two-axis drive system. The CSM is also used as a precharging unit for larger drives to prevent damage to rectifiers. Its compact size allows mounting inside a standard control cabinet alongside other S120 components.
