High Precision 4-Digit and Power Display: IKococater 60V 5A DC benchtop power supply is a professional power supply regulation device that has a high resolution of 0.01V and 0.001A. You can easily tune it within 0-60V and 0-5A. The backlit 4-digit LED display provides a more accurate readout for the voltage and current value, visible easily even in the low-light conditions..
Set Values by Accurate Encoder Knob: Just "set" Voltage and Current instead of "adjust". You can press the Voltage and Current encoder knob to select the Digit you want to adjust, then rotate the knob to set the value from 0-13. 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..
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 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 benchtop DC power supply more secure and more energy saving..
