ALSTOM AL129A Power Supply Module In-Stock

The AL129A (often listed as AL129A CD101152) is a critical Power Supply Module

primarily used in industrial automation and control systems.

It was originally manufactured by Alstom (and later GE following their acquisition

of Alstom’s power business).

It is a "chopper converter" style power module specifically designed for the Alspa

CE2000 and CE3000 series controllers, which are commonly found in power plants,

gas turbines, and HVDC (High Voltage Direct Current) transmission systems.

Common Applications Power Generation: Providing stable power to controllers for

gas, steam, and hydroelectric turbines.

Grid Infrastructure: Used in substation automation and HVDC systems to ensure

reliable protection and control equipment operation.

Industrial Automation: Integrated into complex control systems requiring high-efficiency

power conversion and "isolated" outputs to protect sensitive electronic components.

Status and Availability Since the Alspa CE2000/3000 series is an older platform,

the AL129A is frequently categorized as a "legacy" or "discontinued" part.

You will most commonly find it through specialized industrial surplus suppliers or

as a refurbished unit with a test certificate (often under the Alstom code U0100050).
