Technical Parameters
Core Advantages
1. Proven SINAMICS S120 Platform
The SINAMICS S120 is Siemens' flagship modular drive system for high-performance single-axis and multi-axis motion control. The Basic Line Module is a core component of this ecosystem, providing reliable DC power infeed for drive lineups in machine tools, packaging machinery, printing presses, textile machines, and other demanding applications .
2. High Power Density for Multi-Axis Systems
With a 400 kW rated power at 400 V and 820 A input current, this module delivers substantial power in a compact chassis format. For applications requiring even higher power, up to four identical Basic Line Modules can be connected in parallel on a common supply system .
3. Cost-Effective Infeed Solution
The Basic Line Module is designed for applications where energy does not need to be fed back into the supply system. By eliminating regenerative capability, it provides a cost-effective infeed solution for drive lineups that do not have significant regenerative energy requirements. This makes it ideal for many industrial applications where braking energy is dissipated as heat .
4. Integrated Pre-Charging
The module includes a fully controlled thyristor bridge that handles DC link pre-charging for the Basic Line Module and all connected Motor Modules. The thyristors normally operate with a trigger delay angle of 0°, ensuring smooth and controlled startup .
5. Seamless System Integration
The Basic Line Module connects to the SINAMICS S120 Control Unit via the included DRIVE-CLiQ cable, enabling seamless communication within the drive lineup. Commissioning is performed using Siemens STARTER engineering tool, with the module controlled via standard telegram communication .
6. Line Reactor Ready
For proper operation, a line reactor appropriate to the supply conditions must typically be installed. The line reactor protects the converter from excessive harmonic currents and limits line harmonic distortion to permissible values. In configurations using a transformer with appropriate rating (6-pulse with one BLM, 12-pulse with two BLMs), the line reactor may be optional .
Applications
The 6SL3330-1TE38-2AA3 Basic Line Module is deployed across a wide range of multi-axis drive applications:

Frequently Asked Questions (FAQ)
Q1: What is the Siemens 6SL3330-1TE38-2AA3?
It is a Basic Line Module for the SINAMICS S120 drive system. It converts three-phase AC line power (380–480 V) into a regulated DC link voltage (510–650 V DC) to supply connected Motor Modules in a multi-axis drive configuration .
Q2: What is the power rating of this module?
The rated power is 400 kW at 400 V, with a maximum power of 600 kW. Rated input current is 820 A at 380–480 V AC .
Q3: What does "two-quadrant operation" mean?
Two-quadrant operation means the Basic Line Module can only supply power (infeed) but cannot feed regenerative energy back into the supply system. If regenerative energy is produced (e.g., during motor braking), it must be dissipated as heat using a Braking Module and braking resistor .
Q4: What is the difference between Basic Line Module, Smart Line Module, and Active Line Module?
-
Basic Line Module (BLM): Two-quadrant operation (infeed only), no regenerative feedback
-
Smart Line Module (SLM): Four-quadrant operation with regenerative feedback capability
-
Active Line Module (ALM): Four-quadrant operation with active filtering for lowest harmonic distortion
Q5: What DC link voltage does this module provide?
The DC link output voltage is 510–650 V DC. Under full load, the DC link voltage is typically 1.32 × line voltage; under partial load, 1.35 × line voltage .
Q6: Is a line reactor required?
For most supply conditions, a line reactor should be provided at the connection point. The line reactor protects the converter from excessive harmonic currents and limits line harmonic distortion. However, it may be optional if the infeed is realized via a transformer with appropriate rating (6-pulse with one BLM, 12-pulse with two BLMs) .
Q7: Can this module be connected in parallel for higher power?
Yes. Up to four identical Basic Line Modules can be connected in parallel on a common supply system to increase the total power rating. For parallel connection, line reactors are included in the associated Line Connection Modules .
Q8: What is the protection class and cooling method?
The module has an IP00 protection class and uses internal air cooling. It must be installed in a protected cabinet environment .
Q9: What is the operating temperature range?
The module operates from 0 to +40°C without derating, and up to +55°C with derating .
Q10: What is the net weight?
Approximately 86 kg .
Q11: Is this a genuine Siemens product?
Yes. This is a new and original Siemens product with article number 6SL3330-1TE38-2AA3. The product lifecycle status is PM300: Active Product .
Q12: What is included with the module?
The module includes a DRIVE-CLiQ cable for connection to the Control Unit .
