Product description

Siemens 6RA2281-6DS22-0 identifies a DC converter in the SIMOREG K series and 6RA24 device family. The microprocessor-based version is a single-quadrant drive with a B6C bridge circuit. Mains connection is three-phase AC. For this 6DS22 version, Siemens specifies 400 V AC rated voltage, 485 V DC rated voltage and 400 A rated DC current. The complete manufacturer/order/identification number identifies the exact current and voltage class. Its type code is D485/400 MRE-GEEF6S22. The Siemens type table assigns 6RA2281-6DS22-0 to this D485/400 version. Rated-operation values are 194 kW rated power and approximately 1,250 W power loss. Maximum field-rectifier DC voltage is 325 V. Permissible ambient temperature with forced ventilation is 0 to 35 °C. Degree of protection is IP00. These values describe electrical ratings, control method and enclosure version of the individual converter. The dimension drawing for device class D 400–600 shows 210 mm width, 625 mm overall height and 275 mm depth. Complete external dimensions are therefore 210 × 625 × 275 mm in width × height × depth order. Approximate device weight in the Siemens manual is ca. 31 kg. Dimensions and weight refer to the individual converter. Order number, type code, 400 V AC, 485 V DC, 400 A, IP00, dimensions and weight are the central technical values of this SIMOREG K version. Further technical values are automatic mains adaptation from 45 to 65 Hz, 194 kW rated power, approximately 1,250 W power loss, maximum 325 V field DC voltage and an ambient range up to 35 °C with forced ventilation.
