The Aoyuan AYS198Y-045 is a 4.5V 40A switching power supply designed for LED display cabinets, video walls, and digital signage. It operates from a universal 100–240VAC input range and delivers 180W of stable, efficient power. Its regulated 4.5V DC output helps reduce heat generation, protect sensitive driver ICs, lower power consumption, and extend the service life of LED display panels.

Key Features

· Wide 100-240VAC Input Range: Built to handle varying voltage stabilities worldwide, ensuring seamless operation across different regional electrical grids.

· Low-Heat 4.5V Output: Reduces energy wasted as heat compared to traditional 5V power supplies, keeping sealed LED cabinets running cooler.

· Ultra-Slim Profile: Features a low-profile mechanical footprint that easily slides into the tightly restricted spaces behind modular video panel frameworks.

· Built-in Safety Protections: Keeps your display components safe with built-in safeguards against over-temperature, overload, under-voltage, over-current, and short-circuits.

· Certified Compliance: Fully certified with CE and CCC standards, ensuring safety, reliability, and regulatory compliance for commercial installations.

· Flexible Product Series: Part of a versatile, scalable power series designed to match exact panel voltage requirements for fine-tuned display performance.
