Partial Load Efficiency Of S120 Smart Line Modules; Partial Load Efficiency Of S120 Active Line Modules + Active Interface Modules - Siemens SINAMICS G130 Engineering Manual

1.14.2.3 Partial load efficiency of S120 Smart Line Modules

The chart below shows the partial-load efficiency of air-cooled SINAMICS S120 Smart Line Modules.The calculations
are based on a typical efficiency at full load of 98.5 %. The efficiency is represented as a function of the active output
power ratio P /P supplied to the connected SINAMICS S120 Motor Modules by the SLM or drawn from the
Out Out-100
connected SINAMICS S120 Motor Modules by the SLM and regenerated to the mains supply.

1.14.2.4 Partial load efficiency of S120 Active Line Modules + Active Interface Modules

The chart below shows the partial-load efficiency of air-cooled and liquid-cooled SINAMICS S120 Active Line
Modules including the assigned air-cooled Active Interface Modules. The calculations are based on typical efficiency
values at full load. These are 98.5 % with Active Line Modules and 99 % with the assigned Active Interface Modules,
corresponding to a total efficiency η
