Description
The Mornsun LI120-20B24R2S 120W AC/DC DIN-Rail Power Supply is a robust, highly efficient power conversion unit engineered to deliver a stable and reliable 24V DC output at 5A. Designed specifically for industrial automation environments and equipment racks, this 120W power supply features a space-saving ultra-slim DIN-rail mounting design (compatible with TS-35/7.5 or 15 rails) that ensures secure placement and minimizes space consumption inside cramped control cabinets.
Equipped with a universal input voltage range of 90-264VAC or 127-370VDC, it flexibly accepts either AC or DC input from the same terminal block. Engineered for high reliability in demanding conditions, the unit features a high I/O isolation test voltage of up to 4000VAC, low ripple and noise, and comprehensive multi-layer output protections against short-circuits, over-current, over-voltage, and over-temperature. Certified according to rigorous international safety standards including UL61010 and UL508, the LI120-20B24R2S provides an exceptional, long-lasting power solution for industrial control panels and automation machinery.
