| Note | Note 1 : Please add the new requirement when the power supply will be used for high humidity condition. Note 2: Ripple & noise test: Ripple & noise bandwidth is set to 20MHz, use a 0. 10uF ceramic capacitor in parallel with a 10.0uF electrolytic capacitor at output connector for ripple & noise measurements. Note 3:Efficiency:Terminal output voltage multiplied by the output current, and then divided by the AC input voltage, divided by the AC input current, divided by the power factor: efficiency=terminal output voltage X output current / (the AC input voltage X AC input current X power factor). Note 4: The power delay time measured is when AC power on to 90% of specified output voltage observed on the channel. Note 5: The hold-up time measured is when AC power off to 90% of specified output voltage observed on the channel. Note 6: The rise time measured is when the output voltage rise from 10% to 90% of specified output Vout observed on the channel wave form. | |
