Notes：

①For product models with output voltages of ±5VDC and ±9VDC, under 0% - 5% load conditions, the maximum output voltage accuracy is ±5%;

②When tested under 0%-00% load working conditions, the index of load regulation rate is ±5%;

③0%-5% load ripple & noise le than or equal to 5%Vo. Ripple and noise test method Twisted pair test method, which can add capacitive load at the output to

reduce light load ripple.
