Note:
(1) For product model with output voltage ±5VDC or ±9VDC , the maximum output voltage accuracy is ±5% under 0% - 5% load condition
(2) When tested according to the 0%-00% load working condition, the load adjustment rate is ±5%
(3) 0%-5% load ripple & noise less than or equal to 5% Vo. Ripple and noise test method, Twisted pair test method, can add capacitive load at the output to reduce light load ripple
