Siemens SINAMICS DCM DC Converter and Control Module

5. Certification qualifications

In addition to UL/cUL certification, the product also complies with GOST standards and has been certified by Lloyd's Register, Det Norske Veritas, American Bureau of Shipping, and Germanischer Lloyd (ship certification requires radio interference suppression filters and M08 option - coated PCB).

Typical model technical parameters (taking 480V three-phase AC and four quadrant operation as an example)

For the series models with rated armature supply voltage of 480V three-phase AC (± 10%/-20%) and four quadrant operation, the core parameters are shown in the following table (some key models):

Model Rated armature input current (A) Rated DC voltage (V) Rated DC current (A) Rated power (kW) Rated excitation voltage (V) Rated excitation current (A) Cooling air demand (m ³/h) Sound pressure level (dB (A)) Size (W × H × D, mm) Weight (kg)

6RA8091-6FV62-0AA0 996 500 1200 600 480 two-phase AC 40-268 × 785 × 435-

Note: The armature/excitation supply voltage can be set to be lower than the rated value through parameter settings. The minimum input voltage for 400/480/575V rated voltage equipment is 50V, and for higher rated voltage equipment it is 85V. When the supply voltage undervoltage is ≤ 5%, the rated DC output voltage can be maintained.

Selection and ordering data

1. Core dimensions for selection

Selection should be based on armature circuit parameters (supply voltage, rated DC voltage/current), excitation circuit parameters (supply voltage, rated DC current), rated power, matched with corresponding models and matching fuses. Different supply voltages (400V/480V/575V/690V/830V/950V three-phase AC) correspond to different model sequences, for example:

400V three-phase AC: 6RA80xx-6DV62-0AA0 series

480V three-phase AC: 6RA80xx-6FV62-0AA0 series

575/690V three-phase AC: 6RA80xx-6GV62-0AA0 series

2. Rules for matching fuses

Different models require specific types and specifications of armature/excitation circuit fuses, such as:

6RA8013-6FV62-0AA0 (480V three-phase AC, 15A rated DC current): armature fuse 3NE1814-0 (2 pieces), excitation fuse 5SD420

6RA8087-6FV62-0AA0 (480V three-phase AC, 850A rated DC current): armature fuse 3NE3338-8+3NE3334-0B (parallel), excitation fuse 5SD480

High current models (such as 6RA8091-6FV62-0AA01200A rated DC current): Built in armature fuse, no external semiconductor fuse required, excitation fuse 3NE1802-0 (UL certified)
