• Series 6RA70 SIMOREG DC MASTER converters are characterized by their compact, spacesaving
  construction. Their compact design makes them particularly easy to service and maintain
  since individual components are readily accessible. The electronics box contains the basic
  electronic circuitry as well as any supplementary boards.
• All SIMOREG DC MASTER units are equipped with a PMU simple operator panel mounted in the
  converter door. The panel consists of a five-digit, seven-segment display, three LEDs as status
  indicators and three parameterization keys. The PMU also features connector X300 with a USS
  interface in accordance with the RS232 or RS485 standard.
• The panel provides all the facilities for making adjustments or settings and displaying measured
  values required to start up the converter.
• The OP1S optional converter operator panel can be mounted either in the converter door or
  externally, e.g. in the cubicle door. For this purpose, it can be connected up by means of a 5 m long
  cable. Cables of up to 200 m in length can be used if a separate 5 V supply is available. The OP1S
  is connected to the SIMOREG via connector X300. The OP1S can be installed as an economic
  alternative to control cubicle measuring instruments which display physical measured quantities.
• The OP1S features an LCD with 4 x 16 characters for displaying parameter names in plaintext.
  German, English, French, Spanish and Italian can be selected as the display languages.
• The OP1S can store parameter sets for easy downloading to other devices.
  The converter can also be parameterized on a standard PC with appropriate software connected to
  the serial interface on the basic unit. This PC interface is used during start-up, for maintenance
  during shutdown and for diagnosis in operation. Furthermore, converter software upgrades can be
  loaded via this interface for storage in a Flash memory.
• On single-quadrant converters, the armature is supplied via a fully controlled three-phase bridge
  B6C and, on four-quadrant devices, via two fully controlled three-phase bridges in circulatingcurrent-
  free, inverse-parallel connection (B6)A(B6)C.
• The field is supplied via a single-phase, branch-pair half-controlled 2-pulse bridge connection
  B2HZ.
• The frequencies of the armature and field supply voltages may be different (in a range from 45 to
  65 Hz). Operation in the extended frequency range between 23 Hz and 110 Hz is available on
  request. The armature circuit supply phase sequence is insignificant.
• For converters with 15A to 850A (1200A at 400V supply voltage) rated DC current, the power
  section for armature and field is constructed of isolated thyristor modules. The heat sink is thus
  electrically isolated. On devices with a higher rated DC current, the power section for the armature
  circuit is constructed of disk thyristors and heat sinks (thyristor assemblies) at voltage potential. The
  housing and terminal covers on power connections provide protection against accidental contact for
  operators working in the vicinity. All connecting terminals are accessible from the front.
