Output Specifications Model DC Output Voltage Load (2) Min. Max. Ripple (1) P-P (max) Regulation Line Load 5% 2% 50V (per port) 0A 0.35A 20KHz 300mVp-p PSM275-909 >20KHz 50mVp-p 2% 5% 12V 0.75A 6.25A Note: (1) Noise is measured with resistor load (not as electronic load). The output is decoupled with 10uF bulk electrolytic and 0.1uF ceramic capacitor. Measurement is made with a high impedance probe connected across the decoupling capacitance. Band width limited to 100mHz. (2) The sum of total powered ports cannot exceed 200W. Phihong reserves the right to make changes without further notice. Please consult Phihong USA and visit www.phihong.com for the most up-to-date specifications.
