ALSTOMA AL129A is a high-voltage power supply module (such as a converter, a traction system, or a component of an electric drive unit) for industrial or transit applications, designed for power conversion, motor drive, or DC/AC power distribution, commonly in the following scenarios:

Rail transit: train traction system, auxiliary power supply unit (APU).

Industrial drive: high power motor drive, converter supporting.

Power system: high voltage direct current transmission (HVDC) equipment, grid voltage regulator module.

2. Core Functions (Speculation)

High voltage conversion: support AC/DC or DC/DC conversion, adapt to different grid or load demand.

Energy feedback: In the case of braking or load change, the excess energy is returned to the grid or energy storage unit.

Dynamic voltage regulation: ensure the stable operation of the equipment under voltage fluctuation by quickly adjusting the output.

Module redundancy: Part of the design supports parallel redundancy to improve system reliability (such as critical power equipment).

3. Technical parameters (typical value reference)

Description of project parameters

Input voltage DC 1500V or AC 3 phase 380-3000V (depending on the application scenario)

Output power 100kW-1MW (subject to the actual model)

Efficiency ≥95% (at full load)

Cooling mode Air cooling/liquid cooling (high power models require forced cooling)

Protection grade IP54 (rail transit) or IP20 (cabinet installation)

Communication interface CAN, RS485, Ethernet (optional)

4. Application areas

Rail transit: main power module of traction converter for subway and high-speed rail.

Industrial energy: steel mill drive, mine heavy equipment power supply system.

Renewable energy: wind power converter, photovoltaic inverter core components.

Power infrastructure: high voltage direct current (HVDC) station power unit.
