1. INTRODUCTION
The series of switching power supplies for measuring instrument have ruled out the inconvenience of big
volume 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 more
handy and precise adjustment.
Features:
z With more extensive range of input voltage at 97V~133V (for 115V) and 195V~265V (for 230V).
z With high frequency operation can reduce the size of power transformer.
z
With small size, light weight and high density power.
z Entire efficiency rate higher up to 70%.
z
Auto control the voltage and current mode.
z Zero adjustment for the output of voltage and current.
