Project Description

  • PS-305DM Upgrade Version
  • PS-305DM Package

PS series power supply is a kind of continuously adjustable linear DC voltage regulator power supply with high stability, high reliability and low noise. Its output voltage and current can be continuously adjusted. Also it can be both as constant voltage and constant current dc power supply. Its constant voltage and current can be auto-conversion. This low cost and universal power supply can be used in many different areas, from production lines to school use.


1. Automatically switch mA display when current less then 1A 
2. Voltage/current adjust knob with rough and meticulous adjustable
3. Constant voltage and constant current operation
4. Low ripple and noise
5. Affordable and easy to operate
6. Have current limitation protection
7. Upgrade with carry handle, easy to move


1. Educational Laboratories
