When we use low-dropout switching power switching converter to reduce positive input voltage, we usually need an extra low - power negative output voltage.
在采用降压开关功率开关转换器降低正输入电压的同时，通常还需要一个额外的低功率负输出电压。
Before connecting this unit, please make sure that the input and output terminal, and the positive and negative polarities of output terminal are on the right position respectively.
使用时请注意区分输入端与输出端，以及输出端的正负极性，核对无误后才能通电；
The input ends of positive phase and negative phase of the first time-delay unit are respectively connected with the output ends of positive phase and negative phase of the last time-delay unit.
