1The product is small in volume, advanced in function, good in effect, strong in maneuverability and high in precision. 2Open or close the output: You can press the ON/OFF button to open or close the output on any interface. 3Lock the button to avoid wrong operation: On any interface, you can keep pressing coding potentiometer for 2 seconds, all buttons are locked. Keep pressing coding potentiometer for 2 seconds to unlock all buttons. You can see the key lock/unlock icon on 4M0-M9 ten data groups: M0 group is the boot default data group. When you extract the data group you need, this data group will cover M0 data group and be automatically stored on M0 data group. 5You can fast extract shortcut storage data group M1 or M2 and extract the specified data group. Description: The constant voltage and constant current programmable control power supply module is cabinet and delicate, and it puts the collection of analog integration and digital control functions in one. Its adjustable output voltage range is 0-20.0V, step by 0.1V. Its adjustable output current range is 0-2.00A, step by 0.01A. Boot voltages can be stored freely and the model has two groups of quick storage voltage. Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required. LCD display on the model has the function of digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power and LCD brightness. Features: 1.
