SourceLeader DSP-400W3V8/ DSP-400W4V2/ DSP-400W4V6/ DSP-400W5V0 LED Display Switching Power Supply

SourceLeader DSP-400W3V8/ DSP-400W4V2/ DSP-400W4V6/ DSP-400W5V0 LED Display Switching Power Supply Description

The SourceLeader DSP‑400W Series LED Display Switching Power Supply is a high-performance, industrial-grade power solution specifically designed for LED screens of various sizes. Covering four models—DSP‑400W3V8 (3.8V, 304W), DSP‑400W4V2 (4.2V, 336W), DSP‑400W4V6 (4.6V, 368W), and DSP‑400W5V0 (5.0V, 400W)—this series delivers stable, reliable DC power suitable for both indoor and outdoor LED displays. Its universal AC input (100–240V, 50/60Hz) makes it compatible with global voltage standards, while its compact size (235×60×30 mm) allows for flexible installation in various display setups. Designed with high efficiency (up to 90%), high power factor (up to 0.95), and multiple protection features, the DSP‑400W series ensures continuous operation in demanding environments. The natural cooling, fanless design eliminates noise and reduces maintenance, while the built-in LED power indicator provides real-time status monitoring. These features make it ideal for professional LED display applications, such as advertising screens, stadium displays, and conference video walls.
