SINAMICS G180 – the converter for drives with explosion-protected motors

  • Entry
  • Associated product(s)
The SINAMICS G180 low-voltage converter is based on the well-proven series of Loher Dynavert T units. Over decades, Loher developed these units specifically for controlling explosion-protected motors. 30 years of motor know-how and drive engineering were incorporated in these units.

When it comes to drives in the oil&gas/chemical industry, it is not only important that motors and converters reliably operate 24 hours a day, 365 days a year, but also that they have the maximum degree of safety with the highest efficiency of the drive comprising motor and converter. Further, the sector strictly complies with standards and compatibility.

Satisfying these properties, SINAMICS G180 is the standard drive for oil&gas and chemical applications:

  • Power range, 2.2 kW – 6600 kW

  • Standard, user-optimized operation

  • Full output voltage

  • Pulse pattern optimized for the motor – optimum motor utilization
    (low losses, noise, temperature rise)

  • Namur interface

  • Du/dt filter as standard when using line motors

  • Pretested and harmonized system (plug and play)

  • As a result of IDS, no certification costs for the drive combinations (motor/converter)

  • ATEX certified PTC thermistor evaluation (SIL1)

As a consequence, for all process-related applications in oil&gas/chemical industry, we recommend the SINAMICS G180 series of units.

The G150; S150; S120 products are still available for all auxiliary processes.

In order to already address customer requirements in the quotation phase, the SINAMICS G180 series should be quoted for all applications in the oil&gas/chemical industry

The drive portfolio is supplemented by the matching and optimized motor series:

  • Loher motors in explosion protected and non-explosion protected versions

  • High power rating: SIMOTICS TN (Trans standard)
