Features DC Buck Boost Converter: The constant voltage and constant current programmable control power supply module put the collection of analog integration and digital control functions in one. Function: This module has power-down stored function and can store 10 groups preset value. And it also has the function of extracting quickly two groups stored value. Multifunction: LCD display on the module has the function digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power, etc. Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required. Convenient to Use: On the output state remind area, you can see that output opens or not, the state of constant voltage and constant current, output is normal or not, the key is locked or not, and the current data groups that is being used. On the setting data interface, you can adjust over-voltage value, over-current value, over-power value, data set and LCD brightness. Wide Range of Applications: This module has many advantages, small size, advanced function, good visual effect, high operability, high-precision, being used independently, being inset into the device and been widely applied.
