This constant voltage and constant current programmable control power supply module makes analog integration and digital control functions combined in one. It has power-down storage function, which can store 10 groups of preset value and quickly extract two groups of stored value. Compared with traditional power supply module, it is more convenient to quickly extract the voltage or current required. Integrated with the function voltmeter and ammeter, it shows real time voltage and current clearly on the LCD screen. This module features small size, advanced function, good visual effect, strong operability, high accuracy , independent use, embedded use and more. Features: 1. The product is small in volume, advanced in function, good in effect, strong in maneuverability and high in accuracy. 2. Open or close the output: You can press the ON/OFF button to open or close the output on any interface. 3. Lock 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 the right of the screen. 4. M0-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. 5. You can quickly extract shortcut storage data group M1 or M2 and extract the specified data group.
