Great Wall GW-LED300-5 LED Display Switching Power Supply
$58.00
The Great Wall GW-LED300-5 is a 300W 5V switching power supply for professional LED displays, offering wide AC input, low ripple, full protection features, free-air cooling, and MTBF >30,000 hours.
Great Wall GW-LED300-5 LED Display Switching Power Supply Description
The Great Wall GW-LED300-5 is a 300W switching power supply engineered for professional LED display systems. It accepts a wide AC input range (selectable 88–132VAC or 176–264VAC), delivers a regulated 5V output (adjustable 4.75–5.25V) with up to 60A output current and 300W total power, and provides stable performance with low ripple and high power factor. Designed for reliability, the unit includes comprehensive protections (overload, overvoltage, short-circuit, over-temperature), meets international safety and EMC standards, and survives rigorous burn-in testing. With free-air convection cooling, robust environmental tolerances, and an MTBF exceeding 30,000 hours, the GW-LED300-5 is suitable for LED cabinets, modules, signboards, and industrial 5V LED systems.
