MEAN WELL have introduced a new series of 320W AC/DC low profile enclosed type switching power supply ~ RSP-320 series. By reducing the height of original SP-320 series (50mm→30mm), RSP-320 are 40% smaller in size (only 30mm in height) and 1~9% higher in working efficiency compared to the corresponding models. The -30~+70℃ operating temperature range is even wider than the -20~+65℃range of SP-320 series. If compared to the performance and dimension, RSP-320 series are superior to the SP-320, especially for end users who are concerned about energy-saving, limited space for installation, as well as low cost.

With up-to-date high frequency / high efficiency circuit topology, RSP-320 series is equipped with PFC function and possess up to 90% high efficiency, so it can be cooled by the built-in long life DC fan from -30℃ to +50℃ ambient temperature under full load condition, and even up to +70℃ by suitable derating. In order to fit in with a humid and dusty environment, these new units provide optional conformal coating models (RSP-320-□CC), which have basic anti-moisture and anti-dust ability by the coating material on the PCB. In addition, to fulfill the low profile and low output voltage demands from LED display manufacturers, RSP-320 series also provide 2.5V/3.3V/4V/5V (60A) models for their selection. Other built-in functions include fan speed control, protections for short circuit, overload, over voltage and over temperature. All series comply with UL, CUL, TUV, CB, and CE regulations that can guarantee your safety. Applications include general industrial control systems, mechanical and electrical industry, instruments, LED display, or any systems requiring low profile installations.
