Please read this manual carefully before operating the power supply.
1. Introduction
The variable DC power supplies covered in this manual are regulated linear DC power supplies designed for laboratory,
school and manufacturing applications. The output voltage and current can both be continuously adjusted from 0 to
maximum rated value by means of the coarse and fine potentiometers. As linear power supplies, they have excellent ripple
and load regulation, and are suitable for general electronic design work. These power supplies can be used as constant voltage
source or constant current source. All of the models come with over-voltage, so you can also use them for electroplating,
anodizing, battery charging, and DC motor testing, etc.
