Description
Hangte Siqi LPU400S5Y6 LED Display Switching Power Supply Description
The LPU400S5Y6 is a 400W fanless SMPS designed for LED display cabinets, delivering a tightly regulated 5V/0–80A output from a wide 90–264Vac input. Typical efficiency is 90% with PF 0.95. It features short-circuit and over-current protection (auto recovery) and is qualified through 100% full-load burn-in. For proper thermal performance, install with firm contact to a metal baseplate; output power derates with ambient temperature.
Product Features:
• 5V single output, up to 80A (400W) for LED display cabinets.
• Universal AC input 90–264Vac, 47–63Hz; ≤6A input current; ≤50A inrush current.
• High efficiency 90% (typical); power factor 0.95; ≤6W no-load power.
• Protections: short-circuit (auto recovery); over-current 90–110A (auto recovery).
• Ripple & noise <200 mVp-p; start-up time 2 s; stable regulation and low temp. coefficient.
• Fanless natural-convection cooling; mount flat to metal plate for heat dissipation; power derates with ambient temperature.
• Safety/EMC designed per GB/EN/IEC standards for information technology equipment and EMC immunity.
