Features: Easier to Set Values: Encoder switch is used on DC power supply 2021 version to replace the potentiometer switch which is widely used but not easy to adjust. On this version you can just â??setâ?? Voltage and Current instead of â??adjustâ??. Make works accurate, easy and fast. 4 Groups of Internal Memories: You can set 4 groups of commonly used Voltage and Current combination and easily recall them by press â??M1-M4â??. Use the â??ADJUSTâ?? knob to set new combinations. Output Switch Control: Sometimes we need to switch between different voltage or current outputs, but we often forget to unplug the previous instrument and cause it to burn out, which often occurs in the maintenance. Output switch is designed to solve this problem. By pressing the On/Off key, the required voltage and current can be adjusted without the actual output power, which makes this bench-top DC power supply more secure and more energy efficient.
