INTRODUCTION:

The series of switching power supplies for measuring instrument have ruled out the inconvenience of bigvolume and heavyweight of a traditional power supply possess.The output voltage and current is controlled by two variable resistors with coarse and fine regulation for morehandy and precise adjustment.

Features:

1.With more extensive range of input voltage at 230V plus mn10% 50Hz(115V plus mn10 % 60 Hz)

2.With high frequency operation can reduce the size of power transformer.

3.With small size, light weight and high density power.

4.Entire efficiency rate higher up to 70%.

5.Zero adjustment for the output of voltage and current.

6.Intelligent temperature-controlled fan, operating above 50℃
