High‑Efficiency Redundant Power for ABB AC500 PLC Automation Systems
1. Core Product Overview
The ABB 500PSM03/500PSM03A (order code: 1MRB150038R1) is a high‑efficiency 100W industrial power supply module designed for the ABB AC500 PLC series, serving as the core power unit for AC500 CPU, I/O modules and peripheral automation components in critical industrial processes requiring high availability. 500PSM03A is a supply chain variant of the 500PSM03 base model, with identical core performance and compatibility, optimized for global industrial power grids with dual input support for 85-264V AC and 110-300V DC, and delivering regulated 24V DC/4.2A output with ultra‑low ripple (<50mV). It supports seamless 1+1 redundant power configuration, enabling parallel connection of two modules for uninterrupted system operation during single module failure. Built with industrial‑grade ruggedness, it integrates multi‑level electrical protection, IEC‑compliant EMC/surge safeguards and thermal management, operating stably in -20°C to +70°C harsh environments with strong electromagnetic interference and extreme temperatures. Fully compatible with all AC500 series components, it achieves plug‑and‑play installation with FBP bus auto‑recognition, making it an essential component for building stable and fault‑tolerant AC500 automation systems.

2. Power Performance & Electrical Specs
The 500PSM03/500PSM03A 1MRB150038R1 features a dual‑input design supporting both 85-264V AC (50/60Hz) and 110-300V DC, adapting to global industrial power grids and DC power systems without voltage adjustment, and tolerating ±20% input voltage fluctuations to ensure stable power supply in sites with unstable mains power. It outputs regulated 24V DC with a rated current of 4.2A (100W power capacity), capable of powering a full AC500 system including 1 CPU module and up to 30 I/O modules, with ultra‑low output ripple (<50mV) and voltage accuracy (±1%) to protect sensitive PLC electronic components. The module has a high conversion efficiency of up to 92%, reducing power loss and heat generation. It supports 1+1 redundant power configuration—two 500PSM03/500PSM03A modules can be connected in parallel with built‑in ORing diodes to realize seamless power switchover (<5ms) in case of single module failure, ensuring uninterrupted operation of critical industrial processes.

3. Protection Features & Industrial Ruggedness
The 500PSM03/500PSM03A 1MRB150038R1 is built with a multi‑level integrated protection system to ensure the safety of the module and connected AC500 components. It includes overvoltage protection (28V DC output cutoff), overcurrent protection (auto‑current limiting), short‑circuit protection (auto‑shutdown with recovery) and thermal overload protection (temperature‑based power cut)—all protection functions are self‑recovering after fault elimination, no manual reset needed. The module complies with IEC 61000‑4 EMC/surge protection standards, with built‑in surge suppressors and EMC filters to resist electromagnetic interference from industrial equipment (frequency converters, high‑voltage motors) and power grid surges. Designed for industrial environments, it has anti‑vibration (5-50Hz, IEC 60068) and anti‑shock performance, and an IP20 front panel protection rating to prevent dust and accidental contact, operating stably in -20°C to +70°C extreme temperature ranges.
