输出电压可调范围（V）：电源内部设定,外部不可调
Adjustable output voltage range (V):power supply inside the set,external non adjustable
外部信号高电平和悬空有输出
The external signal high level and dangling outputs
在负载跃变频率不超过1KHz的情况下,负载电流以额定输出电流的30%—90%—30%间变动时,测量的输出回路上的超调电压值.动态响应时间：不大于50ms.
In the step load change frequency is less than 1KHz,the load current to the rated output current 30% - 90% - 30% changes,the overshoot voltage output circuit on the measurement of value.Dynamic response time:not more than 50ms.
