Siemens 6SL3912-5EP38-0AA0 Midpoint Diode Power Card

Description

The Siemens 6SL3912-5EP38-0AA0 Midpoint Diode Power Card is an IGBT energy card module designed for paired installation with high-voltage frequency converters. It features three-phase power input, with a rated voltage of 4.16kV and a wide supply voltage range of 1kV to 13kV, making it suitable for matching motors with power ranging from 200kW to 10000kW. The module has a rated current of 550A, uses a voltage-type DC power supply, and adopts VVVF vector control with PWM control for output voltage adjustment, and does not include a built-in filter.

Physically, it has dimensions of 800mm×400mm×300mm and weighs 40kg, with an IP32 protection rating for reliable operation in controlled environments. It operates at ambient temperatures from 0 to 45 degrees Celsius, and can function at altitudes from 0 to 3300 feet, with a service life of 20 years. Communication is achieved via fiber optic connection to digital modulators in control cabinets, and it supports digital input and output types, providing stable, high-performance power conversion for heavy-duty industrial motor applications.
