Note:①At 0%~5% load, the Max. output voltage accuracy of ±5VDC/±9VDC output converter is ±5%.
②When testing from 0% to100%load working conditions，load regulation index of ±5%；
③0%-5% load ripple&Noise is no more than 5%Vo.Ripple and noise are measured by “parallel cable” method, please see DC-DC Converter Application
