Core Advantages
High Efficiency & Energy Saving: Adopts an advanced synchronous rectifier circuit, which greatly improves power conversion efficiency and reduces energy consumption effectively. The built-in power factor correction circuit ensures a power factor (PF) greater than 0.95, optimizing power utilization and reducing harmonic pollution to the power grid, in line with international energy-saving and environmental protection requirements.
Wide Voltage Input & Strong Adaptability: Supports a wide input voltage range of 90~264V AC, compatible with 50~60Hz input frequency, which can adapt to power grid conditions in most regions around the world. No additional voltage conversion equipment is needed, making it convenient for cross-border applications and outdoor complex power supply environments.
Stable Output & Clear Display Effect: Stably outputs 5.0V DC voltage with a voltage regulation accuracy of ±5%, and the output ripple and noise are ≤300mVp-p (tested at 25℃; ≤300mVp-p after 30 minutes of full-load operation at -25℃). The stable power supply ensures uniform brightness of the LED display screen without flicker, effectively enhancing the visual experience of the display terminal.
Comprehensive Safety Protection Mechanisms: Equipped with multiple safety protection functions including input undervoltage protection, output current limiting protection and output short circuit protection. These protection mechanisms can quickly respond to abnormal working conditions, effectively preventing damage to the power supply and connected LED display equipment, ensuring safe and reliable operation of the entire system.
Wide Environmental Adaptability: Designed to operate stably in a wide temperature range of -30℃~+60℃ (please refer to the environmental temperature and load relationship curve for use), and the storage temperature range covers -40℃~+85℃. It can adapt to a relative humidity of 10%~90% and an atmospheric pressure of 80~106 Kpa, and is suitable for use at an altitude of up to 2000 meters, capable of withstanding harsh environmental conditions such as high temperature, low temperature and high humidity.
Quiet Operation & Long Service Life: Adopts natural cooling (conduction cooling) method, without a cooling fan, which avoids noise pollution caused by fan operation and equipment damage caused by fan dust jamming. The product uses high-quality components and mature circuit design, and undergoes strict quality control before leaving the factory, with a storage period of up to 2 years under specified conditions (re-inspection is required after expiration), ensuring long-term reliable operation.
