SourceLeader DSM-200W3V8-2V8 LED Display Switching Power Supply Description

The SourceLeader DSM-200W3V8‑2V8 LED Display Switching Power Supply is a dual‑output industrial power solution engineered for modern LED displays that use common cathode modules, such as indoor ultra‑thin screens, small‑pitch LED displays, COB LED panels, and rental display systems. This power supply provides two independent DC outputs—3.8 V (adjustable toward 4.2 V) and 2.8 V—with a maximum combined power of 170 W, enabling precise matching with display modules that have different voltage requirements for RGB channels. Designed with a universal wide AC input and multiple protection features, this switching power supply delivers reliable, efficient, and safe operation in demanding environments.

Product Features:
• Dual output voltages: 3.8 V (adjustable up to 4.2 V) + 2.8 V DC, specially designed for common cathode LED displays, ensuring stable and precise power delivery.
• Maximum output power: 170 W, suitable for medium-sized LED panels and modular display setups.
• High output current: Up to 30 A (3.8 V) + 20 A (2.8 V), providing sufficient power for large or high-brightness LED modules.
• Universal AC input: 100–240 V (supports 90–264 VAC), compatible with global power standards and flexible installation requirements.
• High energy efficiency: Up to 87%, minimizing heat generation and energy consumption for cost-effective operation.
• High power factor: Up to 0.95, reducing electrical losses and improving overall energy utilization.
• Comprehensive protection: UVP (Under Voltage Protection), OVP (Over Voltage Protection), OCP (Over Current Protection), OTP (Over Temperature Protection), SCP (Short Circuit Protection), ensuring reliable and safe operation in various conditions.
• LED power indicator: Provides clear visual monitoring of operational status at a glance.
• Silent operation: Natural convection cooling (fan-less), offering low-maintenance, quiet operation for indoor or outdoor environments.
• Wide operating temperature: -30 °C to +60 °C, suitable for harsh environmental conditions and outdoor applications.
• Certifications: CCC, CE, UL, RoHS, guaranteeing compliance with international safety and quality standards.
