1. INTRODUCTION
This series of switched mode power supplies have removed the inconvenience of big volumes and heavyweight
associated with traditional power supplies.
The output voltage and current are controlled by two variable resistors with coarse and fine regulation for simple and
precise adjustment.
Features:
l Wide input voltage range— 97V~133V (for 115V) and 195V~265V (for 230V).
l With high frequency operation the size of power the transformer is reduced
l With small size, light weight and high power density.
l Entire efficiency rate up to 70%.
l Constant current and constant voltage modes.
l Zero adjustment for the voltage and current output.
