The Mean Well SP-480-48 is an enclosed AC/DC power supply designed for industrial applications. It provides a robust 480W of power with a stable 48V output voltage. The unit accepts a universal AC input range of 88-264VAC and incorporates a built-in active PFC function, ensuring efficient power factor correction.
Key features include adjustable output voltage with a ±10% range, overload protection from 105% to 135%, and over-voltage protection from 115% to 145%. It also includes remote ON/OFF control and remote sense functions for enhanced system integration. The power supply operates within a wide temperature range of -30°C to +70°C (with derating).
With a compact, low-profile design (43mm thickness), it is suitable for chassis mounting. The SP-480-48 meets various safety and EMC standards, including UL60950-1, TUV EN60950-1, CCC GB4943, and EN55022 Class B. Its high power density and reliable performance make it ideal for ITE (Commercial) applications.
The input voltage range is 85-264VAC (or 88-264VAC from manufacturer page) with a DC input range of 124-370VDC.
It provides 48V output at 10A, with a total power of 480W. The output voltage can be adjusted by ±10%.
The operating temperature range is -30 to +70°C, with output derating required above +60°C.
The efficiency is 89% typical.
It includes overload protection at 105-135% of rated output and overvoltage protection at 115-145%.
It is approved to UL60950-1, TUV EN60950-1, and CCC GB4943 safety standards. For EMC, it meets EN55022 class B, EN61000-3-2,3, and EN61000-4-2,3,4,5,6,8,11.
The SP-480-48 is an enclosed AC/DC converter with chassis mount design.
