The ALSTOMA AL129A is a high-efficiency industrial power supply module designed for critical automation systems requiring stable DC power distribution. As part of ALSTOMA’s Guardian Series, this 24VDC output module delivers 10A continuous current with 94% conversion efficiency, making it ideal for PLC control cabinets and motor drive systems. The AL129A features active power factor correction (PFC >0.98) to meet EN 61000-3-2 standards in manufacturing facilities.
With its integrated DIN rail mounting design, the ALSTOMA AL129A provides surge protection up to 4kV for sensitive instrumentation in oil & gas installations. The module’s wide input voltage range (85-264VAC) ensures reliable operation in regions with unstable grid power. Built-in over-temperature shutdown (threshold: 85°C±5%) protects chemical plant DCS systems from thermal overload.

Key Features and Advantages:
Energy optimization: The AL129A achieves Class VI efficiency with <0.5W no-load consumption, reducing energy costs in 24/7 production lines. Its harmonic current emission (THD <10%) complies with strict data center power quality requirements.
Robust protection: Triple-stage input filtering (X/Y capacitors + common mode choke) suppresses 100kHz-1GHz EMI in welding robot cells. Output current limiting with auto-recovery (2-5 cycles) prevents downtime in packaging machinery.
Smart monitoring: LED status indicators display power good/fault conditions through polycarbonate window. Optional PM-BUS communication enables remote health monitoring via MODBUS RTU in water treatment plants.
Application Areas:
The ALSTOMA AL129A is deployed in:
- Automotive Manufacturing: Welding robot controller power
- Renewable Energy: Solar inverter control circuits
- Food Processing: CIP system valve actuators
- Material Handling: Conveyor motor starters
In semiconductor cleanrooms, its EN 61204-3 compliance ensures ripple voltage <1% for precision measurement devices. The module’s 3000m altitude rating supports operation in hydroelectric power stations. IP20 protection prevents conductive dust ingress in cement plant control panels.
