6-216.7.3 General Feature6.7.3.1. EfficiencyThe efficiency is higher than 72% while measuring at nominal line and max. load.6.7.3.2. Hold Up TimeThe hold up time is longer than 16ms at 220VAC input and max. load which is measured fromthe end of the last charging plus to when the main output drop to 95% output voltage.6.7.3.3. Overload ProtectionThe power supply will go into latch off mode against short circuit or over load conditions. Torecovery from over voltage protection must by cycle AC line OFF and ON. The +5V over load is15A max.6.7.3.4. Leakage CurrentThe leakage current is less than 3.5mA while measuring at nominal line and max. load.6.7.3.5. HI-POT test3000Vac for 1 sec. 10mA (input to output)6.7.3.6. Insulation resistance>10Mohm 500Vdc (Input to output)6.7.3.7. AC DropAC input drop to 0V in 1/2 cycle duration and drop to 1/2 input in 1 cycle duration when theminimum input and maximum loading conditions that the output will not be influenced. (at220Vac)6.7.3.8. AC noiseA pulse width 1 uS, +- polarity, square wave, 500 volts input phase 0°C, 20°C, 180°C and 270°Cinfluence for AC input shall not effect the output.6.7.4 Environment Specification6.7.4.1.
