RUZIZAO Bench Power Supply 30V 40A 1200W, High Power DC Power Supply Variable Benchtop Lab Power Supplier with Encoderknob, Adjustable Switching Regulated

2024 Upgrade High Precision Encoder Adjustment: The bench power supply high-precision encoder adjustment knob replaces the hard-to-adjust potentiometer switch to accurately adjust the desired voltage and current values, Rotary knob adjusts each digit in the range of 0-9, and the backlit 4-digit led display accurately displays the voltage and current values, Which can be clearly seen even in low-light environments
With OUTPUT Switch Button to Preset Current and Voltage Values/Stabilize Output: Our bench power supply with output switch button can preset the voltage and current, DC power supply can work normally within the preset rated current and voltage values. The preset function of our output button mainly lies in preventing your product or DC power supply from burning out due to the excessive voltage and current of the product when you connect the power supply to achieve a protective function, only when the output is pressed will the power supply output the set voltage and curren
