RUZIZAO DC Power Supply Variable, 30V 10A Adjustable Switching Regulated with Encoder Adjustment Knob, Lab Bench Output Button 5V/2A USB Interface Battery Charge/Repair/Test

Upgraded Precision Encoder Knob: Just "set" the voltage and current, instead of "adjusting" , you can press the voltage and current encoder knobs to select the number of digits to be adjusted, and then rotate the knobs to set the value between 0 and 9. The encoder switches replace the traditional potentiometer switches that are difficult to adjust, making your job easier, more accurate and more efficient. Output Switch Control: You can set the current directly without "short circuit"! Sometimes we need to switch between different voltage or current outputs, but often we forget to unplug the previous instrument, causing it to burn out, a situation that often occurs in maintenance. The output on/off key is designed to solve this problem, press the output on/off key to adjust the required voltage and current, which makes this DC power more secure and energy efficient. High Precision, C.C/C.V Mode Auto Switching: This bench power supply is a professional power regulator with 0.01V and 0.001A high accuracy, low ripple laboratory power supply. The backlit 4-digit LED display is easy to read even in low light conditions. Constant voltage and constant current modes can be switched automatically. 5V/2A USB Port, Smart Fan: The adjustable power supply comes with a 5V/2A USB fast charging port for charging mobile phones, tablets or other devices. When the operating temperature of the lab power supply exceeds 122 °F/50 °C, the fan will turn on intelligently to dissipate the heat effectively and prolong the service life of the device. Friendly design: Front power on/off button and shock-absorbing rubber feet at the bottom for more comfortable and stable use. Safe and Reliable: The DC power supply is CE and FCC certified with multiple protection functions - earth wire, over-voltage, over-current, over-temperature, and short-circuit protection. Ensures the safety of the operator and all connected electrical equipment.
