This DC power supply 48Vdc output is built with the latest power supply technique and the quality components materials to enable high performance. High-frequency AC-to-DC flyback converter with green-mode power-saving operation enables the 48Vdc power supply to achieve 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 IN4802500 48 volt power supply features full protection to maximize the reliability. These features include OLP(Over Load Protection), OVP(Over Voltage Protection), output short-circuit protection. The 48V power supply 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). The 48V 2.5A is safety certified to IEC/UL/EN 60950-1 and carries the CE mark for the Low Voltage and RoHS Directives. The 48V 2.5 amp power supply is also compliant to EN 55022-B and FCC Class B for radiated and conducted emissions and the IEC 61000-4 immunity and IEC 61000-3-2 harmonic current standards.
