The Aoyuan AYS220Y-042 is a 189W switching power supply built for LED display cabinets, video walls, and digital signage. It runs on a universal 100–240VAC input and provides a regulated 4.2V DC output at up to 45A, which lowers power consumption, minimizes heat generation, protects sensitive driver ICs, and extends the lifespan of LED panels.

Key Features

· Universal Voltage Input: Works with varying global voltage stability across a wide 100–240VAC range for deployment worldwide.

· Low-Heat Operation: Delivers a 4.2V output that cuts down thermal dissipation inside sealed LED enclosures.

· Quadruple Safety Protections: Features built-in circuits that safeguard components against overload, over-voltage, over-temperature, and short circuits.

· Dual Certification: Carries official CE and CCC safety marks to meet strict commercial installation standards.

· Application Flexibility: Belongs to a uniform hardware family offering multiple voltage options to match specific pixel configurations.
