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 in put volt age at 230V±10% 50Hz(115 V±10 % 60 Hz) 
2,With high frequency operat ion can reduce the size of power transform er.
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.
