  • 【Highly Accurate Encoder Adjustment】 Just press the voltage or current encoder knob of the DC power supply to switch between each digit, and then turn the knob to set each digit in the range of 0-9, you can directly and accurately set the voltage or current you want. It is more precise and convenient than traditional knobs.
  • 【Output Switch Control】 In the process of using the variable power supply, you can adjust the voltage and current you need by pressing the output button at any time. This design can prevent you from damaging the appliance because you forget to disconnect the output. Effectively improve your experiment efficiency.
  • 【Automatic Power Calculation】 The bench power supply will automatically calculate the power based on the voltage and current, and display the voltage, current and power on the high-definition four-digit digital display. The accuracy is 0.01V, 0.001A. The bright digital display allows you to use the bench power supply in a dim environment.
  • 【Short Circuit Alarm】 When the load equipment fails and short-circuits, the adjustable dc power supply will emit a buzzer alarm. Prevent excessive output current from damaging the load equipment. In addition, it has multiple protections, such as grounding wire, leakage protection, thermal protection, voltage overload, power supply overload, etc.
