Schneider Electric ABLM1A24012 power supply MODULAR separate 100-240 VAC 24 VDC content_copy

The power supply ABLM1A24012 from Schneider Electric belongs to the Modicon power supply series and is designed as a modular, switched-mode power source for industrial, commercial, and residential applications. It provides a constant output voltage of 24 V DC with a current of 1.25 A, corresponding to a rated power of 30 W. The input voltage is 100–240 V AC at a frequency of 50–60 Hz, with input voltage limits of 90–264 V AC allowing high tolerance to voltage fluctuations. The device is suitable for use in network systems of types TN, TT, and IT and meets the requirements for SELV (safety extra-low voltage) according to IEC 60950-1, IEC 60204-1, and IEC 60364-4-41, ensuring safe power supply for electronic components.

Applications
This power supply is designed for use in enclosures and control systems in industrial and building environments where a reliable and compact power supply is required for controls, sensors, communication modules, or other electronic components. The compact design with dimensions 36 mm (width) × 91 mm (height) × 55.6 mm (depth) enables efficient space utilization. Mounting is possible either on a Top Hat rail (type TH35-15 or TH35-7.5) according to IEC 60715, on a double-profile DIN rail, or via enclosure installation. Input connections are located at the bottom, output connections at the top of the device.

Functions and Features in Detail
The device includes an integrated, non-replaceable fuse rated at 3.15 A. For additional protection, the use of external circuit breakers is recommended, for example, with 4 A or 20 A and curve B or C. Output protection functions include overload and short-circuit protection with automatic reset, as well as over-temperature and over-voltage protection with manual reset. The output voltage is adjustable in the range of 24–28 V, enabling adaptation to specific load requirements. A green LED serves as a status indicator for the output voltage.

Technology Explained Simply
The power supply operates in regulated switching mode, enabling high efficiency and low power loss of 5 W. The efficiency is 87 % at 115 V AC and 230 V AC. Ripple voltage is less than 100 mV, ensuring clean and stable voltage for sensitive electronic loads. Line and load regulation is designed for < 0.5 % with devices connected in series and < 1 % with load variations from 0 to 100 %, guaranteeing high stability of the output voltage. The turn-on time is less than 2 seconds, and the hold-up time is > 20 ms at 115 V AC and > 60 ms at 230 V AC. The device can start loads with a capacitance of up to 3000 µF, ensuring compatibility with capacitive loads such as filters or capacitors.

Compatibility and Accessories
The power supply can be operated in series or parallel configuration, enabling power expansion or redundancy in critical applications. It is compatible with various circuit breakers, for example, models M9F22104 (4 A, C-characteristic) or M9F22120 (20 A, C-characteristic) from Schneider Electric. Other models in the ABLM series, such as ABLM1A24004 or ABLM1A24006, offer alternative output powers and are suitable for modular system expansion.

Mounting and Installation
Mounting is done by clipping onto a top hat rail (TH35-15 or TH35-7.5) or by screw mounting onto a mounting plate. Connections are made via screw terminals designed for cross-sections of 0.5–1.5 mm² (without wire end ferrules) or 0.5–1 mm² (with wire end ferrules). The protection rating IP20 protects against finger contact and solid foreign objects, but not against splashing water or dust. The operating temperature range is from -25 °C to 55 °C without current derating; above 55 °C, current derating occurs at 2.67 % per degree Celsius. The operating altitude is up to 2000 m, with overvoltage category II applying from 2000–5000 m. The device is designed for a service life of 10 years, with an MTBF (mean time between failures) of 2,500,000 hours at 25 °C and full load.

Operational Advantages
The high efficiency, low power loss, and robust construction ensure reliable and low-maintenance power supply. Integrated protection functions increase operational safety, and the modular design enables flexible system expansion. Certifications according to IEC 62368-1, EN/IEC 61010-1, UL 62368-1, and other standards ensure suitability for international markets. Product documentation is accessible via a QR code on the device, simplifying maintenance and fault diagnosis. The Green Premium environmental label provides information on material contents, environmental impacts, and circular economy, supporting sustainability goals.
