Key features

• •【Higher Sensitivity & Precision】This 30V 10A dc power supply has a high resolution of 0.01V and 0.01A.It is designed for laboratories, schools and production lines. Encoder switch is used on LONGWEI 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 "set" Voltage and Current instead of "adjust". Make works accuracy, easy and fast.
• •【High-Quality & Multiple Protections】LONGWEI variable power supply use premium electronic components, provide reliable working status and prolong the product life effectively.The Power Supply comes with over-voltage, over-current, over-power, over-heat, short-circuit, five powerful protection function. In addition, the power supply variable displays voltage, current and power simultaneously and the keyboard can be locked to avoid misoperation.
• •【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 efficient.
• •【4 Groups of Internal Memories】You can set 4 groups of commonly used Voltage and Current combination and easily recall them by press "M1-M4". Use the "ADJUST" knob to set new combinations. Applies for laboratory, school, repair, electrolyzation, electroplate, brush plating, lamp test, aging testing, battery charge, home DIY and other requirements.
• •【With USB & RS485 interface】 Rear USB The Host Computer Software is compatible with WINXP, WIN7, WIN10 system. With RS485 Interface and Support Modbus communication protocol.
