Siemens SINAMICS S120 6SL31357TE312AA3 3-Phase Water Cooling Active Line Module, 380 to 480 VAC Input, 600 VDC Output, 200 A Output, 120 kW

The self-commutated infeed/regenerative feedback units (with IGBTs in infeed and regenerative feedback directions) generate a regulated DC link voltage. This means that the connected motor modules are decoupled from the line voltage. Line voltage fluctuations within the permissible supply tolerances have no effect on the motor voltage. If required, the active line modules can also provide reactive power compensation. Active line modules are designed for connection to grounded TN/TT and non-grounded IT supply systems. Liquid cooled active line modules are especially suitable for applications where installation space is restricted and environmental conditions are harsh. Liquid cooling ensures efficient heat dissipation. Active line modules are always operated together with the associated active interface Modules. These include the necessary pre-charging circuit as well as a Clean power Filter.
