NICE-POWER DC Power Supply Variable, Adjustable Switching Regulated Power Supply 30V 10A with Encoder Coarse & Fine Adjustments Knob, Lab Beach Power Supply with Output Button 5V/2A USB Interface

【2023 Upgraded High-Precision Encoder Knob】DC power supply just "set" Voltage and Current instead of "adjust". You can press DC power supply 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 DC power supply encoder switch replaces the potentiometer switch, making your work easier, more accurate and efficient. 【Output Switch Control】The output switch controls the output of the DC power supply and prevents damage to the load. By pressing the DC power supply OUTPUT key, the required voltage and current can be adjusted without the actual output power, which makes this benchtop DC power supply more secure and more energy saving. 【5V/2A USB Interface】The DC power supply is equipped with a 5V/2A USB port. You can charge any USB device with it such as a smartphone which is waiting for repair, or which is used to take photo during your work. 【Power On/Off Button Front-Mounted】The power button is on the front of DC power supply, making it easier to use and needn't turn to the back to turn on/off DC power supply. 【Precise 4-digit LED Display】The DC power supply is a professional DC power supply regulation device that has a high resolution of 0.01V and 0.01A. You can easily tune bench power supply within 0-30V and 0-10A. The backlit 4-digit LED color display provides a more accurate readout for the voltage and current value, visible easily even in the low-light conditions. 【Stable Vertical Design, Lightweight】 The bench power supply adopts stable vertical design, the rubber feet of shock absorber are at the bottom of DC power supply, which is safer and more stable when using. The size of DC power supply is 8.4*3.3*5.5inch and lab power supply weighs only 2.6lb, very light and small, you can easily carry DC power supply in and out of various workplaces. 【Wide Applications】The adjustable power supply features an intelligent temperature-controlled fan and heat sink for excellent heat dissipation and is especially suitable for laboratory, electronic repair DIY, communication equipment maintenance, products line, scientific research and teaching units.
