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).

ABB Spare parts health and functional check (on-site)

Spare parts health and functional check (on-site)

The spare parts critical to commercial operation (noble parts;

ex.: boards, power supply), will be installed directly on the

existing excitation system and the functionality of all parts will

be confirmed. This will require the excitation system and the

machine to be available for testing.

Spare parts health and functional check (at the factory)

Upon request, the health and functional check may be performed in

our factory. The spare parts must be carefully packed and shipped

to ABB. Once they arrive, they will be inspected and tested at our

supplier factory in order verify their correct functionality. We

recommend that spare part boards (PCB) containing electrolytic

capacitors should be tested every four years.

Parts Fingerprint

The Parts Fingerprint provides you with a complimentary

recommended spare parts list or, if a detailed list of the spare

parts is provided, a list of the recommended parts that are

missing can be prepared. This can be done, for example, as part

of a performance review. We will also keep you informed about

critical aging processes of vital components.

ABB Product and part life cycle report (annual)

Product and part life cycle report (annual)

The Product Life Cycle annual report is a summary of the

excitation system parts availability and life cycle status. It will

also detail which new material can replace the obsolete ones and

if a mechanical adaptation is needed.

Control upgrade solution (preferential price)

ABB has designed a front-end control upgrade solution using the

latest excitation technology, the UNITROL 6000. for excitation

systems in the Limited or Obsolete phase. It is an efficient

solution that extends the life of the system and brings it to the

Active phase of the Product Life Cycle.

Performance review (preferential price)

The ABB performance review program is designed to ensure

the proper and safe operation of all your UNITROL excitation

products. We accomplish this by running tests on all critical

protection devices and system settings in various operating

conditions. We then prepare a report based on the findings, and

make recommendations on how to keep unplanned downtime at

a minimum.

GE OMNI MU360 A Safer and Cybersecure Substation

Test Modes

IEC 61850 edition 2.1 provides standard mechanisms for testing

purposes, reducing commissioning complexity and allowing new bay

installations without affecting substation operation.

With the test modes in MU360 users can independently configure

mode and behavior of each logical devices allowing then to operate

as: On, Test, Blocked, Test/Blocked and Off.

A Safer and Cybersecure Substation

Transmitting the instrument transformers´ measurements digitally

through optical fibers eliminates the risk of inadvertent mishandling

of the current and voltage circuits and makes the relay room a safer

work environment, eliminating hazards and reducing the risk of

personnel injury.

To ensure MU360 have all this connectivity in a cybersecure way, it

has been designed according to IEC 62443 and have all capabilities

described by SL2 of this standard, including RBAC, secure boot and

signed firmware.

Reduce the Engineering Effort and Cost

The use of Process Bus with the MU360 drastically reduces the

need for trenches, ducts, glands, cable trays and copper hardwiring,

as the information is exchanged among IEDs using fiber optic cables

and ethernet switches.

Fewer cables to manage also means reduced engineering complexity

as extensive wiring schematics are replaced by standardized

version-controlled configuration files. Future reconfigurations are

automatically documented by the IED configuration tool.

GE OMNI MU360 Reliable, Interoperable and Future Proof

Flexibility

By integrating binary inputs, outputs, and analogue connections into

one box, the MU360 offers a cost-effective solution for a multitude of

bay configurations. Up to two buses and two lines may be monitored

per box with a flexible configuration of up to 224 binary inputs or 140

binary outputs.

Reliable, Interoperable and Future Proof

The MU360 complies with the main standards for digital

substation IEC 61869-9. IEC 61850 edition 2.1 and IEC 61869

13. which guarantees its interoperability and compliance to the

requirements for being the physical to digital interface of modern

digital substations. Furthermore, measurements of each CT/VT

set may be broadcasted in protection and power quality profiles,

allowing multiple Protection, Automation and Control applications

to consume the data without needing extra footprint for acquisition.
