ABB SPS01 – 24V DC Industrial Power Supply Module
Product Overview
The ABB SPS01 is a regulated switching power supply module engineered for mission-critical industrial automation environments. Part of ABB’s Modular Power System IV (MPS IV) platform, this unit converts 100-240V AC input into a stabilized 24V DC output to power PLC racks, DCS controllers, I/O modules, field sensors, and actuators–2.
Designed for high-density control cabinets, the SPS01 maintains consistent voltage regulation under fluctuating load conditions, preventing system resets and protecting sensitive semiconductor components from power surges-2. Its wide auto-ranging input automatically compensates for voltage sags and surges—a common challenge in remote industrial sites with unstable mains power-2.
The module integrates seamlessly into ABB Symphony Plus, AC 800M, and Harmony rack architectures, supporting N+1 or 1+1 redundant configurations to eliminate single points of failure in continuous process control applications–7. With a fanless design and MTBF exceeding 300,000 hours, the SPS01 delivers the long-term reliability that process industries demand-1-6.

ABB SPS01
Key Features and Benefits
Wide Auto-Ranging Input – The module automatically adapts to any AC voltage between 100V and 240V without manual jumpers, simplifying global deployment and ensuring operation during brownout conditions-6.
Fanless Thermal Management – With efficiency exceeding 90%, the SPS01 generates minimal heat and relies on passive convection cooling. Eliminating the fan removes a common failure point, reduces maintenance, and enables silent operation in control rooms-6.
Hardened Protection Circuitry – Integrated over-voltage, over-current, and short-circuit protections react within milliseconds to safeguard not only the power supply itself but also expensive downstream controllers and I/O cards from field-side electrical faults-6.
Redundancy Ready – The unit supports diode-OR output for seamless 1+1 or N+1 redundant configurations without external decoupling modules, ensuring uninterrupted power to critical control systems-1.
Compact DIN Rail Footprint – The space-efficient form factor enables high-density mounting in control cabinets, with a 35mm DIN rail design that simplifies installation and replacement–2.

Installation and Maintenance
The SPS01 mounts directly onto a standard 35mm DIN rail, making it quick to install or replace without special tools-1-5. For output connections up to 3 meters, use 14 AWG (2.5mm²) wire; for longer runs, 12 AWG (4mm²) is recommended to minimize voltage drop-1.
Status LEDs on the front panel provide real-time diagnostics for AC OK, DC OK, and overload conditions-1. When paired with ABB’s BP03 base plates and monitoring modules, the unit supports hot-swappable maintenance-1. For redundant configurations, leave adequate clearance between adjacent modules on the DIN rail—approximately 20mm—to maintain thermal stability-2.
ABB provides comprehensive documentation including installation guides, product manuals, and troubleshooting resources-5. The SPS01 is backed by a 12-month manufacturer warranty covering defects in materials and workmanship-1.
