Description:
The ABB 1KHL178016R0001F, also designated as PSM03, is a high-efficiency 24 V DC switch-mode power supply module manufactured by ABB for industrial automation systems. Designed for use with ABB AC 800M controllers, S800 I/O stations, and general control cabinet DC distribution, it converts a wide-range AC input (100–240 V AC) into a tightly regulated 24 V DC output at up to 10 A (240 W), with support for N+1 parallel redundant operation to eliminate single points of failure in critical process applications.
Application Scenarios:
In a continuous pharmaceutical water-treatment skid integrated into a plant-wide System 800xA DCS, the local S800 I/O rack and Profibus DP coupler must remain powered even during brief mains sags or a single power-supply failure. Originally equipped with a standalone non-redundant PSU, the panel suffered an unplanned shutdown when the sole supply failed during a weekend. The maintenance team upgraded to a dual ABB 1KHL178016R0001F PSM03 configuration in N+1 redundant parallel mode. Now, if one unit is taken offline for service or fails, the second seamlessly carries the full 24 V DC load with no interruption to the I/O rack or communication modules. The front-panel DC OK / Fault LEDs give technicians instant visual confirmation of supply health during daily walkthroughs, and the wide-input design accommodates the site’s occasional 208 V AC / 230 V AC swing without adjustment—directly solving the pain point of fragile single-source DC power in validated GMP environments.

Technical Principles and Innovative Values:
- Innovation Point 1: Universal Auto-Ranging AC Input with Active PFC. The ABB 1KHL178016R0001F accepts 100–240 V AC globally without manual voltage selector—ideal for multinational projects and sites with unstable grid conditions. Active Power Factor Correction (PFC) reduces harmonic distortion and improves energy efficiency versus linear supplies.
- Innovation Point 2: N+1 Parallel Redundancy with Dynamic Current Sharing. Unlike basic PSUs that cannot be paralleled safely, the PSM03 is engineered for parallel operation. Two or more units distribute load proportionally, and the system tolerates the removal or failure of one module without dropping the 24 V DC bus—a cornerstone feature for SIL-rated or continuous-process DCS architectures.
- Innovation Point 3: Low-Ripple Regulated Output & Built-In Diagnostics. Output ripple is typically < 50 mV p-p, ensuring clean power for sensitive analog measurement circuits. Integrated LEDs and a dry-contact / logic-ready status output (on some PSM variants) allow the DCS to monitor PSU health remotely, turning a silent failure into an actionable alarm before a process trip occurs.
Application Cases and Industry Value:
Case 1: Oil & Gas Offshore Platform DCS Panel – Middle EastA produced-water injection skid’s local S800 I/O and AC 800M Compact controller were previously fed by a single 24 V DC PSU. After a PSU failure caused a 4-hour shutdown during well-testing, the panel was retrofitted with two ABB 1KHL178016R0001F PSM03 modules in redundant parallel. Over 24 months post-retrofit, one unit was proactively replaced during a shutdown with zero process interruption. The platform reported zero PSU-related trips since the upgrade and appreciated the simplified DIN-rail mounting versus the previous panel-mount unit.Case 2: Food & Beverage Batch Mixer – EuropeA mixer control cabinet required stable 24 V DC for 6 S800 analog input modules, an HMI, and 12 digital outputs driving solenoid banks. The ABB PSM03 was selected for its 10 A capacity and >93% efficiency in a warm (45 °C ambient) wash-down-area cabinet with limited ventilation. The supply ran cool and maintained voltage within ±0.3 V under full load. The plant’s maintenance log showed no PSU-related faults in the first 18 months, and the unit’s compact footprint freed space for a future Ethernet switch.
