SMKAN DP20V2A Constant Voltage Constant Current Programmable Control Step-down Supply Power Module

  • The constant voltage and constant current programmable control power supply module is cabinet and delicate, and it put the collection of analog integration and digital control functions in one. Its adjustable output voltage range is 0-20.0V, step by 0.1V. Its adjustable output current range is 0-2.00A, step by 0.01A. Boot voltages can be stored freely and the model has two groups of quick storage voltage. Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required. LCD display on the model has the function digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power and LCD brightness..
  • Adjusting preset voltage:Pressing SET button, page down to U-SET, press the codding potentiometer, then enter toadjustnumeric value. Press codding potentiometer in turn to choose the numeric value you want to adjust. Turn codding potentiometer to adjust the numeric value. If you want toexit adjusting voltage, press shortly SET. In the process of adjusting preset voltage, if you open output voltage mode by pressing the ON/OFF, the output voltage will be refreshing by increasing or decreasing the numeric value.
