UL certification brings peace of mind! 24V4A desktop power adapter (5.5x2.5mm connector) for compliant and stable power supply.

　　A small PLC power supply for export to the North American market is stuck at customs because it lacks UL certification. Are you using a standard power supply for precision laboratory instruments, fearing safety issues and rejection? Are cross-border DIY users purchasing power supplies afraid to use them due to the lack of authoritative North American certification? The root cause of these "compliant power supply issues" is that the power supply lacks UL certification. As North America's most stringent safety standard, UL certification is the "pass" for devices entering the North American market and ensuring safety in high-end applications. Standard power supplies simply cannot replace it.

　　Even if traditional desktop power supplies are labeled "safety protection," most are not UL certified. They either have excessive leakage current (>3.5mA), failing to meet the UL 62368-1 requirements for protection against electric shock; or have a flame retardancy rating of only V-2, making them susceptible to fire when exposed to high temperatures. Worse still, some fail abnormal temperature rise testing, causing them to overheat over time, posing a safety risk. The UL-certified 24V4A desktop power adapter (with a 5.5x2.5mm DC connector) completely resolves compliance and safety concerns. UL 62368-1 certification, sufficient power, and a universal connector ensure worry-free access to the North American market and provide more stable power for high-end scenarios.

　　Why does it achieve both compliance and practicality? Four core advantages, enhanced safety.

　　1. UL 62368-1 certified, ensuring smooth access to the North American market.

　　Developed in strict accordance with the UL 62368-1 safety standard for information technology equipment, it has passed 108 rigorous tests: leakage current ≤ 0.75mA (well below the UL standard's upper limit of 3.5mA), providing enhanced protection against electric shock. The housing is made of V-0 flame-retardant material, with no reflammage after 30 seconds at 750°C. After undergoing 124V overvoltage input testing, 4.8A overload testing, and 21-day burn-in testing, all indicators meet UL certification requirements, earning it a UL certificate (certification number available for verification). Whether used in industrial equipment exported to the US and Canada or in local North American laboratories and factories, it can easily pass customs, quarantine, and safety inspections.

　　2. 24V4A Full Power, 96W Output

　　Utilizing a high-frequency switching power supply solution, it boasts a rated 24V DC output and 4A constant current, delivering a full 96W of power. During UL certification testing, it maintained a voltage fluctuation of ≤±0.5V over 10 hours of continuous full-load operation. It is compatible with mainstream North American equipment, including industrial Rockwell Micro800 series PLCs and Danaher sensors, laboratory small spectrometers and chromatograph accessories, and cross-border DIY 3D printer heated beds (North American 110V input). Voltage ripple is ≤50mV, meeting UL's low-interference requirements for powering precision equipment, ensuring zero-error data acquisition.

　　3. 5.5x2.5mm Universal Connector, Directly Compatible with North American Devices

　　Equipped with a UL-certified 5.5x2.5mm DC connector (positive inside, negative outside), it's compatible with over 85% of 24V devices in North America. These include HID controllers, portable medical oximeters (such as the Contec North American version), common DIY table saws (Ryobi models), and even some small North American coffee machines. These can all be plugged in directly without the need for adapters (UL standards prohibit the risks associated with non-certified adapters). The connector features a 3μm gold plating layer and a plug-in/plug-out lifespan of over 5,000 cycles. It has passed UL plug-in durability testing, ensuring stable contact even with long-term use.

　　4. Nine-layer safety protection, UL-rated peace of mind

　　Building on the existing four-layer protection, this product has been upgraded with UL-exclusive protection: new undervoltage protection (automatic power-off when input <85V), surge protection (withstands 1.2/50μs 6kV surges), and electromagnetic compatibility (EMC) protection. It has passed UL electromagnetic radiation testing (radiation value ≤30dBμV/m). The body temperature remains ≤55°C under full load (UL standard ≤70°C), and the non-slip silicone pad on the bottom has passed UL anti-slip coefficient testing (static friction coefficient ≥0.6). It features a wide 100-240V input (compatible with North American 110V power grids) and comes with a 1.8m UL-certified power cord (with a NEMA 5-15 plug) for direct plugging into North American outlets.
