1.     The ripple values are measured at 20MHz of bandwidth by using a 12'' twisted pair-wire termin-ated with 0.1uF & 47uF parallel capacitor under ambient temperature 25°C at rated input voltage and rated load;
2.     The efficiency values are measured under ambient temperature 25°C at rated input voltage and rat-ed load.

Output voltage adjustment range |
Output voltage can be adjusted within above range by V-ADJ. variable resistance inside of the power supply. When output voltage exceeds the range, the power supply will be in failure or get into over voltage protection mode. To avoid the case that the output voltage is higher than rated voltage, output current should be used under rated current |
