[Upgraded High-precision encoder knob]Just "set" Voltage and Current instead of "adjust". You can the Voltage and Current encoder knob to select the Digit you want to adjust, then rotate the knob to set the value from 0-9. Each Digit can be set easily by the accurate encoder knob. The encoder switch replaces the potentiometer switch, making your work easier, more accurate and efficient. [Precise 3-digit LED Display]The DC bench power supply has a resolution of 0.1V and 0.01A, and you can easily adjust it in the range of 0-30V and 0-5A. The 3-digit back-lit LED display provides more accurate and clearly visible readings for the voltage and current value, even in conditions of low voltage. [Small and Diverse Applications]Worried about the bulky power supply? This compact and sophisticated DC power supply weighs much less than a laptop at just 1.54 pounds, saving more space on your workbench. And you can use it in scenarios such as laboratory, repair, electrolysis, burn-in test, electroplating, brush plating, electronic DIY, etc. [Safe and Reliable to Use] The built-in fan low arc noise & low ripple,The power supply is and compact. Productive work since the power supply comes multiple protection of Over-voltage, over-current, over-power, over-temperature, short-circuit powerful protection function.
