This ac/dc adapter 15V 5A is built with the latest power supply technologies and the quality components materials to enable high performance. High-frequency AC-to-DC flyback converter with green-mode power-saving operation enables high power density and lowest no-load power consumption, to comply with global efficiency standards including DoE Level VI and EU CoC V5 Tier-2. The IN1505000 ac dc adapter 15V output features full protection to maximize the reliability. These features include OLP(Over Load Protection), OVP(Over Voltage Protection), output short-circuit protection to prevent the circuit from being damaged in abnormal conditions. The 15 volt ac adapter provides good EMI, high PF and low total harmonic distortion (THD) over the universal input voltage. The 15V AC adapter incorporates a pair of U shaped internal heat sinks to achieve efficient natural convection cooling, that enables higher operating temperatures and reliability (see our UL/TUV certification).
