Introduction to the AMG Systems 12V 24W DIN-rail Power Supply (AMGPSU-I12-P24)
The AMG Systems AMGPSU-I12-P24 is a compact DIN-rail power supply engineered to deliver reliable 12 VDC power at up to 24 W (2 A). Targeted at CCTV, networked security devices and small industrial installations, this module combines a small footprint with wide input capability, built-in protections and a design intended for rugged environments. While AMG lists the AMGPSU-I12-P24 as obsolete, the closely matched AMGPSU-I12-P24A is the active variant — installers should confirm which variant and datasheet to reference when specifying or purchasing.

Detailed specifications and benefits
Understanding the electrical, mechanical and compliance specifications helps determine whether this supply fits a particular project. Below are the key specification groups and the practical benefits they deliver.
- Output voltage:12 VDC nominal. The original AMGPSU-I12-P24 provides 12 VDC with an adjustable range; the A variant extends adjustment to 11–14 V to better accommodate different load requirements.
- Output current / power:2 A and 24 W — suitable for small camera clusters, access control panels, PoE splitters and similar low-power devices.
- Voltage adjustment:Original units offer approximately 10.8–13.8 V adjustment; the A variant is specified at 11–14 V, allowing installers to compensate for cable drop or to meet input requirements of sensitive equipment.
- Input range:85–264 VAC (universal) and 120–370 VDC for dual-use installations. The A variant tightens the listed AC start range to ≈90–264 VAC in some AMG documentation. Wide input range adds flexibility for global deployments and DC-fed systems.
- Efficiency:Greater than 90% efficiency reduces wasted energy and heat build-up inside cabinets, improving reliability and lowering cooling needs.
- Isolation & surge handling:I/O isolation rated at 4,000 VAC and surge withstand capability of 300 VAC for 5 seconds — important for protecting connected electronics in electrically noisy or surge-prone environments.
- Operating temperature:Original: −40°C to +70°C; A variant: −25°C to +70°C. The broad upper range supports hot outdoor enclosures and heated cabinets; verify the lower bound for extreme cold locations.
- Storage temperature:−40°C to +85°C.
- IP rating:IP20 — intended for indoor cabinet or enclosed outdoor housings rather than exposed outdoor mounting.
- Mounting:DIN-rail for easy integration into standard control cabinets and pole-mounted enclosures.
- Dimensions:Approx. 35 × 58 × 90–93 mm — very compact, freeing space in dense assemblies.
- MTBF:300,000 h (original) / 900,000 h (A variant) — the improved MTBF on the A model suggests longer expected service life under rated conditions.
- Certifications:Listed to UL62368-1 and EN/BS EN62368 series EMC/safety standards per AMG documentation — a key consideration for commercial and industrial projects.
- Protections:Short-circuit, over-current and over-voltage protections protect both the supply and downstream devices, reducing risk during commissioning and fault conditions.
- Warranty:AMG offers a 3-year support warranty, giving systems integrators and end users confidence in product support.
Overall, the combination of adjustable output, robust protections, compact form factor and efficient operation makes this supply particularly attractive where space is constrained and reliability is important.
Use cases and scenarios where this power supply excels
The AMG 12 VDC 24 W DIN-rail PSU is well suited to a variety of low-power, space-conscious applications. Typical scenarios include:
- CCTV and security systems:Powering individual cameras, junction boxes, IR illuminators or small clusters of cameras where local 12 V rails are preferred over PoE for legacy or specialized devices.
- Networked security devices:Small NVR accessory modules, alarm panels, access control readers and communication modules that require regulated 12 VDC.
- Control cabinets and automation racks:Providing auxiliary 12 V rail in industrial control cabinets for sensors, relays and gateways.
- Field/remote deployments:Installations with mixed AC and DC sources, or where a wide input range simplifies inventory and supports DC bus architectures.
- Space-constrained installs:Dense cabinets, pole-mounted junction enclosures and service vehicles where a compact DIN-rail mounted supply reduces footprint while maintaining protective features.
In practice, integrators often choose a supply like the AMGPSU-I12-P24 when they need a reliable, small-form regulated 12 V source that can withstand industrial temperature ranges and provide meaningful protection for connected devices.
How it compares with similar products on the market
DIN-rail power supplies are a broad category and several manufacturers produce units that target the same applications. Key comparison points to consider:
- Power class and size:The 24 W / 2 A power class sits between the very small 5–15 W modules and larger 30–60 W industrial supplies. Compared with bulkier higher-power units, the AMG 24 W model offers a much smaller footprint while still delivering sufficient power for many cameras and accessories.
- Input flexibility:The wide AC/DC input range rivals many industrial-grade supplies and can reduce the need for multiple SKUs across regions or for DC-fed systems.
- Efficiency:Efficiency >90% is competitive in this class — higher efficiency lowers thermal stress and can obviate extra ventilation in dense cabinets.
- Protections:Short-circuit, over-current and over-voltage protections are commonly expected in this segment. The AMG unit’s combination of protections and I/O isolation rating (4,000 VAC) is favorable compared with some low-cost consumer-style supplies that omit industrial-grade isolation or surge handling.
- Environmental specs:The wide operating temperature (particularly the original −40°C lower bound) can be an advantage for very cold climates, while some competing models trade that range for cost savings. The A variant’s adjusted lower limit (−25°C) still suits most deployments but is worth verifying against site requirements.
- Warranty and support:A 3-year support warranty is competitive; some commodity supplies offer 1–2 year warranties, while higher-end industrial brands may offer comparable or longer coverage.
In short, compared to entry-level supplies the AMG offers stronger environmental, protection and efficiency characteristics; compared to high-end industrial supplies it competes on size and price while offering the essentials most integrators need for CCTV and small automation tasks.
Customer feedback and typical reviews
There are no official public testimonials included with the product brief, but typical feedback themes from installers and integrators using similarly specified AMG DIN-rail supplies include:
- "Reliable and compact — fits neatly into small junction boxes and handles camera power without getting hot."
- "Good value for money — the price point and 3-year support make it attractive for large projects."
- "Adjustable output is handy for compensating voltage drop on long camera runs."
- "We appreciate the wide input range and surge tolerance for installations on sites with noisy power."
These representative comments reflect typical advantages noted by field technicians: compactness, adjustability, robust protections and sensible warranty support. For specific project references, integrators should request case studies or contact AMG for validated customer lists.
Conclusion: Why choose the AMGPSU-I12-P24?
The AMG Systems AMGPSU-I12-P24 (and its active AMGPSU-I12-P24A variant) offers a compelling balance of compact size, industrial features and useful protections for CCTV, network devices and general 12 VDC applications. Its wide input range and high efficiency make it versatile across global mains standards and DC-fed systems, while the DIN-rail form factor simplifies installation in cabinets and enclosures. The adjustable output and robust isolation/surge specifications reduce integration headaches with sensitive downstream equipment.
For integrators and system designers seeking a small, reliable 12 V supply with sensible protections and a competitive price point (suggested retail ~ $69.99), this AMG module is a practical choice. Be mindful that AMG lists the I12-P24 as obsolete and documents the I12-P24A as the active variant — always confirm the correct variant and datasheet with AMG or your supplier to match the exact adjustment range, operating temperature and MTBF to your deployment needs.
In summary, the AMGPSU-I12-P24 family is well-suited for projects where space is limited, reliability is required and a regulated 12 V rail is needed to power cameras, access control, sensors and similar devices. Its combination of efficiency, protections and warranty support make it a sound selection for commercial and light industrial installations.
