Product Overview
The ABB SA168 3BSE003389R1 is a high-reliability power supply unit (PSU) designed to deliver stable DC power for critical industrial automation systems. As part of ABB’s SA series, this module converts 230V AC input voltage into 24V DC output at 25A continuous current, ensuring consistent power delivery for control panels, PLCs, and distributed control systems (DCS) in manufacturing, energy, and infrastructure applications. Its switch-mode topology offers 92% efficiency, minimizing energy loss and heat generation, while the compact form factor (150 x 100 x 80 mm) optimizes space in crowded control cabinets.
Equipped with overload, overvoltage, and over-temperature protection, the ABB SA168 3BSE003389R1 safeguards connected equipment from voltage spikes and thermal stress. The module’s DIN rail mounting (EN 50022) simplifies installation, and its IP20-rated enclosure prevents dust ingress and accidental contact. Built-in LED indicators provide real-time status feedback for input/output voltage and fault conditions, streamlining diagnostics and maintenance.
Compliant with IEC 61000-6-2 (EMC immunity) and UL 508 standards, the ABB SA168 3BSE003389R1 ensures global interoperability and safety in mission-critical environments. It integrates seamlessly with ABB’s AC800M DCS and PLC-500 systems, enabling centralized monitoring and predictive maintenance via ABB’s Ability™ digital platform.
