【Product Introduction in English】

The S-120-15V series switching power supply is a DC regulated power module specifically engineered for industrial automation, communication systems, and electronic control applications. Utilizing advanced high-frequency conversion technology, this product features compact dimensions, superior energy efficiency, and exceptional operational stability. With a universal AC input range of 100-240V, it automatically adapts to global power grid standards, delivering a regulated 15V DC output. The maximum load current reaches 8A with 120W continuous output power, ensuring reliable power supply for various equipment.

Integrated with multi-level protection mechanisms including over-voltage, over-current, and short-circuit safeguards, this unit significantly enhances system durability. The fully enclosed metal enclosure achieves dual advantages: optimized thermal management maintains stable operation within a broad temperature range of -20℃ to +60℃, while superior electromagnetic compatibility minimizes interference with adjacent devices. Equipped with precision voltage regulation circuitry, the output ripple coefficient remains below 1%, providing clean power for sensitive instrumentation.

This product is ideal for LED display systems, industrial control equipment, security surveillance devices, and medical apparatus. The specially designed terminal block enables tool-free installation, meeting industrial-grade vibration resistance requirements. Rigorous aging tests guarantee a mean time between failures exceeding 50,000 hours, effectively reducing maintenance costs. Two installation options are available: wall-mounting and DIN rail-mounting configurations, both compatible with standard 35mm industrial rails.
