151X1233DB02SA02 General Electric 10kW Wind Turbine DC Pitch Converter, Rev A

Product Description

151X1233DB02SA02 Rev A is a heavy-duty DC pitch converter from GE 151X series for wind turbine pitch control systems. This integrated power conversion assembly consists of BAA control board, CAA power board and converter/diode assembly, with 10kW continuous output and peak power up to 25kW, nominal 100A current rating. It converts DC power and drives pitch servo motors to adjust wind turbine blade angles, maintaining stable wind capture and overspeed protection. It is certified with UL 508C and CSA standards and designed to withstand harsh vibration and temperature conditions inside wind nacelles.
