SourceLeader DSM-500W4V2-3V2 LED Display Switching Power Supply Description

The SourceLeader DSM‑500W4V2‑3V2 LED Display Switching Power Supply is a high-performance, reliable, and efficient industrial power solution for LED display systems, delivering dual outputs of 4.2 V and 3.2 V with maximum currents of 65 A and 35 A, providing up to 385 W of total power. It supports a wide AC input range of 100–240 V (90–264 V) with a high power factor up to 0.95 and efficiency up to 88 %, ensuring energy-saving operation and minimal heat generation. Featuring dual-channel common cathode outputs, LED power indicator, natural cooling for silent and low-maintenance operation, and comprehensive protections including UVP, OVP, OCP, OTP, and SCP, it operates reliably in temperatures from -30 °C to +60 °C. Certified with CCC, CE, FCC, and RoHS, it is ideal for outdoor energy-saving display screens, common cathode screens, and negative-pressure output display applications.

Product Features:
• Wide Universal Input: 100–240VAC input supports global power standards and simplifies installation on varied sites.
• Dual Output Design: Provides 4.2V and 3.2V outputs concurrently (0–65A and 0–35A), supporting different LED modules or circuits with flexible power distribution.
• High Power Efficiency: Efficiency of up to 88% reduces energy loss and heat generation during operation, which contributes to lower operating costs and energy consumption.
• Wide Operating Temperature: Engineered for harsh environments with operational capability from –30°C to +60°C.
• All‑Around Protection: Comprehensive protection including under‑voltage (UVP), over‑voltage (OVP), over‑current (OCP), over‑temperature (OTP), and short‑circuit protection (SCP) to safeguard both the power supply and your LED display system.
• Natural Cooling: No active fans, resulting in quieter operation and reduced maintenance needs.
• LED Power Indicator: Built‑in indicator for easy status monitoring.
• Certifications: Meets international standards with CCC, CE, FCC, and RoHS approvals, ensuring safety and environmental compliance.
• Common Cathode Suitability: Optimized for energy‑saving common cathode displays, a technology that can reduce whole screen power consumption by minimizing voltage redundancy and heat losses compared to traditional designs.

Applications:
• Outdoor energy‑saving LED displays
• Common cathode LED screen installations
• Negative pressure output display systems
