Overview
The Siemens 6SL3225-0BE33-7AA0 (PM250) is a robust power module designed for the modular SINAMICS G120 inverter series. Unlike standard modules, the PM250 features regenerative capability, allowing braking energy to be fed back into the supply system instead of being wasted as heat through resistors.
This unit comes with an integrated Class A line filter and is housed in a Frame Size E (FSE) enclosure with IP20 protection. Please note this is a power module only; a Control Unit (CU) and Basic Operator Panel (BOP) are required for full operation.
Key Function & Features
-
Energy Recovery: Efficiently feeds braking energy back into the grid, reducing operational costs.
-
Integrated Filter: Built-in Class A line filter ensures electromagnetic compatibility.
-
Dual Overload Ratings: * High Overload (HO): 37kW (200% for 3s).
-
Light Overload (LO): 45kW (150% for 3s).
-
-
Robust Cooling: Designed for ambient temperatures up to +50°C.
-
Compact Design: Frame Size E (FSE) dimensions of 635 x 275 x 204 mm.
Benefit
-
Cost Savings: Eliminates the need for external braking resistors and cooling systems for those resistors.
-
Space Efficient: The integrated filter and regenerative technology reduce the overall footprint in the control cabinet.
-
Sustainability: Reduced heat dissipation lowers the energy consumption of cabinet cooling systems.
