Hi,

I am reaching out to all experts familiar with Siemens Sinamics for a specialized application. I am in need of a DC power solution that can provide 1000VDC @ 240Amps, with the ability to handle peak currents up to 640Amps. This power solution is intended to feed a specialized non-Siemens inverter designed for a brushless servomotor.

Inverter:
Helix 640Arms 1200V Silicon Carbide

Has anyone attempted an architecture or configuration that aligns with these requirements?

I am currently considering the following Siemens Sinamics part for this purpose:

• Part Number:6SL3330-6TG35-5AA3
• Product Description:SINAMICS S120 SMART Line Module 3AC 500-690V, 50/60 Hz; Output: DC 675-930V, 550A; Rated Power: 450kW; Built-in Equipment, IP00; Internal Air Cooling; Includes Drive-CLiQ cable.

I would greatly appreciate any insights, experiences, or recommendations related to this particular module or any alternatives that might be suitable for this application.

Please feel free to reach out directly or reply to this thread with your thoughts.

Thank you in advance for your valuable assistance.
