(1) Total output power must not exceed 25W at convection cooling and 40W at 20CFM air flow condition.
(2) Peak output current lasting less than 30 seconds with duty cycle less than 10%. During peak loading, peak
total power must not exceed 40W.
(3) Ripple & noise is measured at 20MHz bandwidth limit by use a 10 inch twisted wire terminated with a 10µf
capacitor in parallel 0.1µf ceramic capacitor.
