Output Voltage 24V Switching Power Supplies (ALRS24V Series)
The ALRS24V series provides a regulated 24 VDC single output and is stocked in 12 current ratings:
0.65A, 1.1A, 1.5A, 2.5A, 4.2A, 5A, 7.5A, 8.4A, 10A, 12.5A, 15A, and 20A —
corresponding to output power from approximately 16W up to 480W.
All models accept a universal 90–264VAC input and achieve efficiency of over 85%.
24V is the industrial standard for PLCs, sensors, and field actuators. Operating at higher voltage reduces cable current and resistive losses over long wiring runs in factory environments. These units feature complete protection (OVP, OCP, SCP), a 5G anti-vibration rating, and a built-in long-life fan for continuous full-load operation from -10°C to +60°C. They comply with international safety regulations and are widely used in industrial automation and scientific research.

Frequently asked questions
What is a switching power supply and how does it work?
A switching power supply (SMPS) converts AC mains voltage to a regulated DC output by rapidly switching a power transistor at high frequency. This method is far more efficient than linear regulators, generating less heat and enabling a compact enclosed form factor — critical for industrial and automation applications.
What output current ratings are available for the 12V series?
The ALRS12V series offers 14 models with output currents of 1.3A, 2.2A, 3A, 5A, 8.4A, 10A, 12.5A, 15A, 16.7A, 20A, 25A, 30A, 40A, and 50A — spanning output power from ~16W to 600W at 12V. All accept 90–264VAC input and achieve efficiency over 80%.
What output current ratings are available for the 24V series?
The ALRS24V series offers 12 models with output currents of 0.65A, 1.1A, 1.5A, 2.5A, 4.2A, 5A, 7.5A, 8.4A, 10A, 12.5A, 15A, and 20A — spanning output power from ~16W to 480W at 24V. All accept 90–264VAC input and achieve efficiency over 85%.
What is the difference between 12V and 24V switching power supplies?
12V supplies are widely used for LED lighting, consumer electronics, and low-power embedded systems. 24V is the industrial standard for PLCs, sensors, and field actuators — higher voltage reduces cable current and resistive losses over longer runs on the factory floor. ATI's 24V series also achieves slightly higher efficiency (>85% vs >80%).
How do I select the right output current rating?
Add up the total current draw of all connected loads, then select a model rated at least 20–30% above that figure for thermal headroom and longer service life. For example, an 8A system is best served by a 10A model such as the ALRS12V10AT or ALRS24V10AT.
Are ATI switching power supplies suitable for harsh environments?
Yes. All ALRS-series units carry a 5G anti-vibration rating and are rated for continuous full-load operation from -10°C to +60°C with a built-in long-life cooling fan. They comply with international safety regulations for factory cabinets, outdoor enclosures, and mobile equipment.
Can ATI supply custom or OEM configurations?
Yes. Customized models are available with application-specific output voltages, current ratings, footprints, connectors, or certifications. Contact ATI with your specifications to request a custom quotation.
