ABB SPS02 – Industrial Power Supply Module
Product Overview
The ABB SPS02 is an industrial switching power supply module designed for distributed control systems (DCS) and programmable logic controller (PLC) environments-. Part of ABB’s SPS power supply series, the SPS02 converts 100-240V AC input into stable 24V DC or 48V DC output (depending on variant), providing isolated power for control modules, communication interfaces, sensors, and actuators-2. The module is widely deployed in ABB Symphony Plus and Symphony Harmony (Network 90) systems, as well as AC 800M and 800xA control architectures-1-. Built with a rugged metal chassis and fanless convection cooling, the ABB SPS02 is engineered for continuous 24/7 operation in demanding industrial settings including chemical plants, power stations, and manufacturing facilities-6. It supports parallel configuration for N+1 redundancy, making it a suitable choice for mission-critical applications where power continuity is essential-6.

Key Features and Benefits — ABB SPS02
- Wide input voltage compatibility — The ABB SPS02 accepts 100-240V AC input without manual switching, simplifying global deployment across different regional power grids-2-6.
- Stable, low-noise DC output — With ±1% output accuracy and ≤50mVp-p ripple and noise, the SPS02 delivers clean power for sensitive control equipment such as PLC CPUs, high-precision sensors, and analog I/O modules-2.
- Robust protection circuitry — Multi-layer safeguards against overload, overvoltage, short-circuit, and thermal events protect both the power supply and connected equipment from damage-6.
- Redundancy-ready architecture — Multiple SPS02 units can be configured in parallel with external diode modules to create N+1 redundant power architectures for mission-critical applications-6.
- Fanless convection cooling — The SPS02 uses passive cooling with no moving parts, eliminating fan failure as a failure point and reducing maintenance requirements. Adequate clearance (minimum 50mm above and below) is recommended for optimal thermal performance-6.
- Diagnostic LED indicators — Front-panel status lights provide instant visual confirmation of output voltage status and fault conditions, enabling rapid troubleshooting-6.
- Hot-swap support — The module supports live replacement without system shutdown, minimizing downtime in continuous process control applications-1.

Installation and Maintenance — ABB SPS02
Mounting: Secure the SPS02 onto a standard 35mm DIN rail. Ensure the module clicks firmly into place and that the rail is properly grounded to the cabinet earth.
Wiring: Connect the AC input to the designated terminals (L, N, and earth). Observe correct polarity for DC output connections. Use appropriately rated cables for 5A continuous current. Shielded cables are recommended for output wiring to minimize EMI.
Grounding: The cabinet frame must connect directly to the plant earth ground. Clean, tight ground connections prevent electrical noise from affecting output stability.
Parallel operation: For redundant configurations, connect multiple SPS02 units through external diode modules. Ensure load sharing is properly configured to prevent uneven current distribution.
Thermal management: Maintain minimum 50mm clearance above and below the module for convection cooling-6. Avoid installing the SPS02 directly above heat-generating equipment.
Periodic checks: Inspect terminal connections for tightness every six months. Verify that LED indicators show normal operation (green = power on, red = fault). Clean dust accumulation from ventilation openings to maintain thermal performance.
