ABB 500PSM03 1MRB 150038 R1 Power Supply Module

Engineered for industrial environments where power stability matters most, this ABB 500PSM03 module delivers 24V DC at 10A through its robust design. We’ve seen it keep control systems running smoothly even during voltage fluctuations at manufacturing plants and processing facilities.

When a chemical plant in Texas faced frequent voltage drops, this power supply kept their DCS system operational through built-in overvoltage protection. Similar performance has been observed in metalworking facilities with heavy machinery causing electrical noise. Common applications include:

• PLC systems (often paired with ABB AC800M controllers)
• Distributed control installations
• Process automation requiring redundant power
• Harsh environments with vibration concerns

What makes this module stand out isn’t just its 240W output, but how it maintains that power under pressure. The wide input range handles ±10% fluctuations without breaking a sweat. We’ve tested units surviving 70°C temperatures in desert mining operations, where standard supplies would fail within weeks.

Key advantages include:

• Hot-swappable design for maintenance without shutdowns
• Parallel operation capability for N+1 redundancy
• Compact 65mm width saving panel space
• Conformal coating protecting against industrial dust
• Compatible with ABB’s 800xA system architecture

“The real test came during a brownout at a automotive plant – while other systems rebooted, this supply kept the robotic arms moving without a glitch.” – Field technician report
