Located in Yueyang, China, this product offers the Siemens SINAMICS S120 drive series from Siemens, along with the Siemens 6SL3320-1TE35-0AA3 book-shaped power module. When we maintain large production lines, we often encounter situations where the drives give alarms or the motors fail to rotate. In many cases, the problem lies in this power module. It converts the rectified direct current into adjustable-frequency alternating current and directly controls the motor speed.
The Siemens 6SL3320-1TE35-0AA3 has excellent surface coating treatment, effectively preventing corrosion and dust intrusion. The front panel design is very professional. The most prominent feature is the row of thick power connection terminals at the bottom, also known as the copper busbar interface. From the appearance, one can feel their strong current-carrying capacity. Above are the control cable interfaces and status indicator lights, with a reasonable layout. Its color is the standard dark gray-black of Siemens, and the features are very distinct.
The core component of the Siemens 6SL3320-1TE35-0AA3 is a power board that integrates IGBT (Insulated Gate Bipolar Transistor). It adopts advanced packaging technology to ensure uniform heat dissipation when large currents pass through. The internal bus design is scientifically reasonable, which can minimize the line inductance and reduce the impact of peak voltage on the motor. The heat sink is dense and thick, ensuring rapid heat dissipation. The back design can be directly clamped onto the standard installation guide rail, or fixed with screws. The terminal blocks are connected by crimping to ensure the contact area and reliability. The structure design is rigorous.s.
This Siemens 6SL3320-1TE35-OAA3 model performs with an extremely "dominant" quality. Its core capability lies in generating stable and controllable three-phase alternating current. With a rated power of 55kW and a rated current of 110A, this data indicates that it can easily drive large fans, water pumps, or heavy conveyor belt motors. It has a strong overload capacity, capable of outputting 1.5 times or even higher currents within a short period to handle the shock during motor startup, which is more than sufficient. Its response speed is extremely fast, capable of precisely executing the instructions from the control unit to achieve precise speed regulation and torque control. It also integrates a safety torque cutoff function, which plays a crucial protective role in emergency stops, and its performance indicators are extremely robust.
When shipping this type of power module, which has both precise circuits and heavy heat sinks, the most worrying issue during transportation is the vibration causing the internal solder joints to come off, or the violent handling causing the connection terminals to be distorted. When Yueyang Tongtu shipped the goods, they were very meticulous. We would first wrap the module in thick anti-static bags to prevent static electricity and moisture. Then, we would put it in a specially customized reinforced cardboard box, filling the sides with high-density foam pads to suspend and fix the module, especially the protruding interface parts would receive special protection. An external wooden frame or a thick five-layer corrugated cardboard box would also be used. No matter whether you choose sea transportation or air transportation, all these layers of security measures can ensure that it arrives at your hands intact, without even a scratch.
