HRPG-300 Series - 300W High Reliability Enclosed Switching Power Supply with +5Vsb & PFC Function



HRPG-300 are a range of miniature high reliability enclosed power supplies with +5Vsb featuring no load power consumption <0.5W, high efficiency, active PFC function and a miniature 1U rack style profile. Possessing up to 89% of high efficiency, it can be cooled by the built-in long life DC fan from -30°C to +50°C ambient temperature under full load condition. Other features include 300VAC input surge immunity for 5 seconds, remote sense function and short circuit, over load (constant current mode), over voltage and over temperature protections.
