【Accurate 4-digit LED display】KUAIQU DC Benchtop Power Supplies have a resolution of 0.1V and 0.01A and 0.1W, which you can easily adjust in the range of 0-120V and 0-3A. The 4-digit backlit LCD display provides more accurate and clearly visible readings of voltage and current values, even under low voltage conditions. 【ON/OFF Switch Control】Sometimes we need to switch between different voltage or current outputs in our experiments or work, but we often forget to turn off the outputs, resulting in load damage. Adjustable DC power supply ON/OFF key is designed to solve this problem, just press the added ON/OFF key, you can easily turn on or off the output. The required voltage and current can be adjusted without actual output power, which makes this desktop DC power supply safer and more energy efficient. In addition, you don't need to remove the load or turn off the power each time, making the variable DC power supply easier and more efficient to use! 【Reliability and Safety】Safety is our priority, all lab power supplies are CE & FCC certified.
