GW Instek SPS Series - Introduction to Switching Power Supplies

1
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:
l With more extensive range of input voltage at 97V~133V (for 115V) and 195V~265V (for 230V).
l With high frequency operation can reduce the size of power transformer.
l With small size, light weight and high density power.
l Entire efficiency rate higher up to 70%.
l Auto control the voltage and current mode.
l Zero adjustment for the output of voltage and current.
