RUZIZAO DC Regulated Power Voltage Current Output Control Push Encoder 4 Sets of Storage USB Charging Low Multiple Current Voltage High Precision

[Memory Memory, Output Switch] The DC power supply variable device is equipped with 4 sets of buttons M1 - M4 with data memory function, which can store 4 sets of frequently used voltage and current value combinations and can be called up at any time, so there is no need to repeatedly enter them. The output switch controls the output of the DC power supply to prevent damage to the load. Encoder Adjustment Knob, Lock Button: The encoder knob helps you adjust the voltage and current quickly and accurately. Press the knob to determine the number of digits to adjust, and turn the button to adjust the desired voltage/current value. The DC power supply's lockout button also prevents you from accidentally touching other buttons to readjust the voltage/current. 【High Precision, 4-bit Color LCD Display】DC Power Supply 120V 3A features high resolution of 0.01V and 0.01A. Through the 4-digit backlit color LCD display on the lab power supply, you can read the voltage and current values more accurately and clearly. [Multi-Protection, Intelligent Temperature Control Fan] Safety is our number one priority. The programmable DC power supply has a built-in intelligent cooling fan, with low noise and low ripple, and the DC power supply variable device has multiple protection functions such as overvoltage, overcurrent, overheating and short circuit protection. [Wide range of applications] Not only can it be used for testing on the production line, but it can also be used for electrical maintenance work. It is also a necessary equipment as a DC regulated power supply for scientific research and educational activities in laboratories. It is also a good gift choice for DIY electronic enthusiasts.
