| Note： ① For product models with output voltages of ±5VDC and ±9VDC, under 0%-5% load conditions, the maximum output voltage accuracy is ±5%; ②When tested under the working conditions of 0%-5% load, the index of the load adjustment rate is ±5%; ③0%-5% load ripple & noise less than or equal to 5% Vo. Ripple and noise test method Twisted pair test method, you can add capacitive load at the output to reduce light load ripple. | ||||||||
Note:
1、The above is only a list of typical products. If you need products beyond the list, please contact our sales. 2、The maximum capacitive load indicates the maximum capacitive load that + VO or - vo can be connected to,If the value is exceeded, the product will not start normally..
