  • Precise encoder knob: HANGELL DC power supply 0-30V 0-10A is different from the ordinary traditional knob, which is adjusted by precision encoder knob, with high precision and strong stability.

It is more convenient to adjust the required voltage and current.
  • Output switch button: The variable dc power supply is equipped with an output switch button, so you can easily turn on or off the output by pressing the output button. You can check the working status through the indicator light on the display screen. When the output is turned off, the voltage and current data can be adjusted anytime and anywhere, effectively preventing the load equipment from being damaged by forgetting to turn off the output.
